Leaks and rumors so far have suggested that Samsung is making a camera beast in the Galaxy S23 Ultra. It could be the smartphone camera to beat this year. A fresh rumor has further hinted that the new Samsung flagship will take smartphone photography up a notch. Tipster Ice Universe says the Galaxy S23 Ultra can capture so good low-light photos as it it has “night vision.”

We don’t yet have a camera sample to look at. But any notable improvement over the Galaxy S22 Ultra should be enough to make the new Samsung flagship a low-light photography champion. The current Ultra can already capture excellent night photos, better than most smartphones out there. But newer devices like the Vivo X90 Pro+ appear to have edged it a little. The Korean firm may retake the crown next month, at least if we are to go by the latest rumor.

The Galaxy S23 Ultra isn’t just about low-light camera performance, of course. It will equip a 200MP primary rear camera, so daylight photos will also capture a lot more detail than most competing phones. We have already seen a few samples from the upcoming phone, and it’s looking quite promising so far. Quality improvement over the Galaxy S22 Ultra is phenomenal, even with an in-development camera software under the hood.

Moreover, there are also hints of Samsung equipping the new flagship with sensor-shift camera stabilization technology. This should help make videos more stable even if you don’t use a stand or tripod. The zoom cameras (3X and 10X) and the ultrawide lens, meanwhile, are said to mostly remain unchanged. The Galaxy S23 Ultra may feature the same sensors found on its predecessor. However, Samsung may still improve image quality with software and algorithmic improvements. We shall find out soon.

The Galaxy S23 series may soon appear in a major leak

Samsung is rumored to launch the Galaxy S23 series on February 1. If true, we are now less than a month away from the official unveiling of the new Galaxy flagships. Ahead of that, the devices have expectedly become the talk of the tech town. Leaks about the Galaxy S23 trio are now coming thick and fast. And if history is any indication, a major leak shouldn’t be too far away, revealing everything we need to know about the next-gen Samsung flagships, including the release dates and pricing. The company hasn’t been good at plugging leaks in recent years. We will keep you posted.

Twelve Most Wanted Photography Fine Art Prints of 2022

[ad_1]

Another year has come and gone. For many, myself included, 2022 brought on significant change & difficult challenges both as a country and in our personal lives. As we began the transition from a pandemic to endemic, getting back to business as usual in many cases, the wake of the economic wave of damage done continues to affect us all with rising interest rates, inflation and general disruption of just about everything financial.

The beginning of the pandemic brought an astounding increase in business for for me throughout 2021 and the final three months of the year exploded in sales as people were boarded up in their homes, staring at empty walls and longing for the nature and travel they had been all but shut off from by the pandemic. Then, like the flip of a switch, 2022 buried its face in the dirt and gasped for air for the majority of the year.

Too Blessed To Be Stressed

Fortunately, as a e-commerce business, I didn’t have to worry about paying my employees, costly overhead or any of the other expenditures and worries that go along with operating a storefront. Many of my friends, competitors and business associates alike weren’t so lucky, with photography galleries and the print shops who produce the artwork both significantly downsizing and in some cases shutting their doors altogether.

All in all, in 2022, my sales decreased by more than 40%. This, at the same time as the cost of doing business, from materials to shipping, rose across the board. Despite the fact that I had to drink a few less cups of Starbucks this year, I still generated 3x more revenue selling art, working for myself, than any year of my life working for someone else and for that I am extremely grateful.

Slanging Rocks | Open Doors

The number one difference between myself and others in the business of fine art who don’t make it is my unwillingness to sit still. When one door closes, I don’t waste time sitting around pouting, I simply go searching for other doors. Through the pandemic, in an effort to keep my creativity exercised, I began dabbing in abstract macro photography of semi precious stones. That decision in 2021 ballooned into an entirely new business in 2022, making up for all revenue lost from the downturn this past year. I try to keep the two businesses separate for the most part but if you’re interested in geology and some of the most beautiful stone and mineral specimens the world has to offer you can follow my other account on Instagram @abstractrocks.

For each and every one of you who supported my business this year, by purchasing by work, trusting me to guide you in the field or simply by supporting me every day in words both online and in person, I want to personally thank you and let you know that you are greatly appreciated by me and my family.

Typically I create these end of the year top ten lists showcasing the most popular work of mine from the past year based strictly on sales. This year I decided to mix it up a bit and share a hybrid list of both my best selling and my personal favorite images created over the past twelve months. I hope you enjoy seeing them as much as I enjoyed capturing them. Here’s to 2023 and all of the opportunity it brings! Without further ado, I present to you in no particular order….

How To Take Incredible Astrophotography Pictures With Your iPhone

[ad_1]

With everything set up and the right lighting conditions, you’re ready to take your astroshot. Your iPhone should automatically switch to Night mode when it detects low light. Tap the RAW icon on the top right to switch to the correct format. Lock the focus on infinity, preferably a star.

By default, iOS auto-selects the capture time. When handheld, it’s limited to one second. However, with the release of the 14, the iPhone can detect when it’s motionless on a tripod and extend the exposure time to 10 to 30 seconds (via Apple).

You can tap the caret icon on top of the camera app to adjust the exposure settings. Slide the capture time to the max. Press the shutter button remotely with your Apple Watch or Airpods (via Apple). Wait for the timer to finish the count (it’ll be displayed in the top-left corner).

If you’re using a third-party camera app, note that it’s limited to 1-second exposures which generate a stack of images exposed for a second. It cannot actually take longer exposures. So, all things considered, the default iOS camera should deliver the best results (via MacRumors). You can further enhance them with editing. Import the shots into your computer or edit them on your phone using the Adobe Lightroom app. The Apple ProRAW format allows you to reduce grain and blur without algorithm magic organically (via Apple).

Level Up Your Wedding Photography Business

[ad_1]

Here are some tips and tricks that help make a wedding photography business successful.

Having worked as a professional wedding photographer for over 10 years now and a keen amateur since way before that, I’m always excited to share what works for me when photographing a couple’s big day. I have (I’ll admit) in the past suffered from GAS, or gear acquisition syndrome, and rather than this being a generally unpleasant odor following me around, it means I’ve bought a lot of unnecessary kit, tried tricks and techniques that didn’t work or were, frankly just more hassle than the problem they were meant to solve.

Prior to the Big Day

  1. Create a gallery for the couple online prior to the day to upload the images into. Then, using your computer, create a QR code that links to your online client photo gallery on your website. I use Zenfolio for my website and client proofing galleries at present and creating the empty gallery before the big day. Finally, printing out the QR code and putting it into a plastic stand is normally the last thing I do after packing and checking all my gear is charged and ready. While there are many free QR code generators out there. Why not try QR Code Monkey as they are great, free and allow customization of the QR code prior to creation and download. This way, on the wedding day, the guests can scan the QR code and bookmark the URL on my website where the gallery resides, which normally results in more print sales from guests and family and less of the “where can I see the pictures of us?” questions. It looks something like this.
  2. Create an online discount code for your shop customized for the happy couple. If they think that you’re creating a specific code for them, they are more likely to share the code with guests and spend money with you.
  3. Hire or at least offer a second photographer for the happy couple. Nothing feels worse than delivering photos of a beautiful bride getting ready with hardly any of the groom, best men, groomsmen and father/s of the respective couple. As photographers, we can’t be in two places at once, and it’s as important to cover the groom getting ready as it is the bride. Remember, because you’ll have lots of extra photos to edit, you should consider adding an extra fee to what you charge your couple for your second photographer to cover the extra work.
  4. Send the happy couple a written guide to what time they should expect things to happen on a typical wedding day and get them to confirm with you what time those events are happening on their day. If you don’t mention that it’s okay for the speeches to happen before the meal and they surprise you with it on the day, it becomes a problem that you’ll have to adapt to. If you don’t know the answer, don’t guess, ask for clarification. A good option is to create a brochure in Adobe InDesign (you can see a copy of my brochure here). Featuring articles, tips, and advice, including a timeline guide for couples as well as images and links to other great suppliers is a good way to catch their attention.
  5. Get the couple to send you a Pinterest board with things they like. Nothing better than seeing pictures that have taken their interest, colors they like, and ideas they have for their wedding. It’s going to make you look more professional if you can offer advice and give examples of things that may have worked for other couples, as well as taking their ideas and running with them.

On the Big Day

  1. Always arrive early. On time is late. Use the extra time to scout locations if it’s the first time you’ve been to the venue. Introduce yourself to the key people, and make sure you meet the wedding coordinator and anyone else who may be of help to you during the day.
  2. Find a safe place to store your equipment. You don’t want to be having to go back and forth to your vehicle to grab things all the time. It needs to be available for your second shooter too.
  3. Get the detail shots done first. Flowers, shoes, dress, something old, something new, something borrowed, something blue. Silver sixpence shots are great and thick double-sided sticky tape to stick it to the bottom of the shoe should be good enough to hold it on for the day. Also a good option is to bring blu-tac. You can get the rings to stand up on their edge if you put a tiny piece of it on the bottom of the rings. This always makes for a great shot. While the bride, groom, and guests are getting ready, it’ll show you are in control of the situation, and subsequently, they will put more faith in you knowing what you’re doing.

  1. Remember to ask permission, but moving stuff in the getting ready room if it’s in the way is a good idea. Better yet, ask the venue if they have a spare room you can use for bridal portraits. The venue just wants to make their rooms look good, and if they can give you access to a clean room for a half-hour, they most likely will. Declutter before you shutter is the rule.
  2. Get the Instagram handles for all the suppliers on the day if you’ve never worked with them before. When you’re writing your blog, tagging them means a much wider reach, and they’ll have great images of their products taken by you that they will want to share (make sure you put a watermark on the image you’re giving them to use as people often forget to credit you).

Essential Things in my Kit Bag

  1. Arsenal 2: I love this bit of kit. It’s so good for automating focus stacking and HDR images, as well as panoramas. It really helps you when you have little time to help get amazing shots.
  2. Godox AD200: small, portable, and versatile. These are awesome for off-camera shots. Make sure you buy the X Pro Trigger too. It’s awesome and easy to have multiple flashes set up very quickly with different power settings. Also, the Godox S2 Speedlight Bracket works well for attaching Bowens style softboxes to light stands. This kit is all reasonably priced for what it is and small enough to pack down into a decent-sized bag, and with multiple head attachments available, it really is a great choice.
  3. Blu Tac:  A must-have for holding shoes in place or standing rings up and sticking to the end of the flowers pin so the groom doesn’t get stuck with it.
  4. Holdfast Moneymaker: I’ve used a lot of straps, and they don’t seem to last, or they aren’t as good as I’d hoped. This is the one camera strap holster system that stays with me at every wedding. It’s not only customizable but very strong, and it looks really cool. 
  5. Buy yourself a set of walkie-talkies. Give one to your second shooter and another to the wedding coordinator or venue’s point of contact. It’s much easier if everyone knows where they are meant to be, and you can keep the bride and groom apart more easily prior to them seeing each other.

Post-wedding Planning

  1. Send the couple the first 50 images out within 24 hours. The advantage of this is they can share them on social media straight away, as many guests will share their smartphone images on social media. I’ve lost count of how many times people will wait until I’ve set up a shot on the day, then try to take the image with their mobile phone over my shoulder and post it the day after.
  2. Taking pictures of every attending guest couple on the day means that you’ll have images for people to purchase as soon as they are edited and uploaded. Some people might not get a chance to get pictures together, and getting dressed up for a wedding is a perfect opportunity for a great image. Get your second photographer to make sure they photograph all the couples attending the wedding.
  3. Get your pictures backed up as soon as you get in. Charge your batteries and put your cards to one side until you deliver your images to your client so that you’re ready for the next shoot.
  4. Set yourself a time limit to edit per day. I’d recommend to edit a max of 45 minutes and then take a break. I find a fresh pair of eyes every day means more quality work gets done. 
  5. For photo culling, why not give Aftershoot a try? It uses AI recognition and your uploads to find all the photos that are in focus and compositionally good and in your style. It then grades them, and you can update the metadata and reload it into Adobe Lightroom. It saves me hours and hours of going through images and culling them prior to the final edits.

Hopefully, these tips and this information will help you if you’re thinking of starting your own wedding business or are already in business and looking to try some new things. If you have any useful ideas or would like to add to what’s here, please drop me a line. I’d love to hear your thoughts.

Possible naked-eye comet will visit Earth for 1st time since Neanderthals in 2023

[ad_1]



An image of the Comet C/2022 E3 (ZTF) taken by astrophotographer Hisayoshi Sato as seen in a still image from a NASA video.

An image of the Comet C/2022 E3 (ZTF) taken by astrophotographer Hisayoshi Sato as seen in a still image from a NASA video.

At the start of 2023 Earth will be visited by a newly discovered comet that may just be bright enough to be spotted with the naked eye. 

The comet, named C/2022 E3 (ZTF), is currently passing through the inner solar system. It will make its closest approach to the sun, or perihelion, on Jan. 12, and will then whip past Earth making its closest passage of our planet, its perigee, between Feb. 1 and Feb. 2.

If the comet continues to brighten as it currently is, it could be visible in dark skies with the naked eye. This is difficult to predict for comets, but even if C/2022 E3 (ZTF) does fade it should still be visible with binoculars or a telescope for a number of days around its close approach.

According to NASA, observers in the Northern Hemisphere will be able to find the comet in the morning sky, as it moves in the direction of the northwest during January. C/2022 E3 (ZTF) will become visible for observers in the Southern Hemisphere in early February 2023.

Observers should look for C/2022 E3 (ZTF) when the moon is dim in the sky, with the new moon on Jan. 21 offering such an opportunity, weather permitting. According to the website Starlust, the comet will be in the Camelopardalis constellation during its close approach.

If you’re hoping to observe C/2022 E3 (ZTF), our guides for the best telescopes and best binoculars are a great place to start. If you’re looking to snap photos of the night sky, check out our guide on how to photograph the moon, as well our best cameras for astrophotography and best lenses for astrophotography.

According to NASA Jet Propulsion Laboratory (JPL), the comet has a period of around 50,000 years. This means that prior to it coming to within around 100 million miles (160 million kilometers) of the sun on Jan. 12 and 26 million miles (42 million kilometers) of Earth on Feb. 2, the last time it came so close was during the Upper Paleolithic period on Earth.

That means the last humans that could have spotted C/2022 E3 (ZTF) were early homo sapiens alive during the last glacial period or “ice age.” So, too, could some say of the last Neanderthals, as that species became extinct around 10,000 years after the last perihelion of C/2022 E3 (ZTF).

Of course, the Neanderthals and early humans wouldn’t have known what C/2022 E3 (ZTF) was, and the comet was identified much more recently than the last ice age. The comet was spotted by the wide-field survey camera at the Zwicky Transient Facility in early March 2022.

Initially appearing to be an asteroid, C/2022 E3 (ZTF) which was inside the orbit of Jupiter at the time, soon began to brighten as comets do. At the time of its discovery, C/2022 E3 (ZTF) had a magnitude of 17.3, brightening to a magnitude 10 in November, and expected to eventually reach magnitude 6. 

Current images of C/2022 E3 (ZTF) show its coma, a surrounding halo of gas and dust, glowing with a greenish hue and a long but faint cometary tail extending from its main body. 

Editor’s Note: If you snap the comet C/2022 E3 (ZTF), and would like to share it with Space.com’s readers, send your photo(s), comments, and your name and location to [email protected].

    Rare alignment of the moon and 4 planets this week!| Jupiter, Saturn, Mercury and Venus

    [ad_1]

    If you’re looking for an awesome gift that’s free this year, just look to the night sky where the Christmas moon lines up with four bright planets in a celestial holiday treat this week. 

    This Christmas (Dec. 25), the young crescent moon will shine with Jupiter, Saturn, Mercury and Venus and will appear to glide past Saturn and Jupiter over the next few days. All five objects will appear in a diagonal line from the south to southwest.

    New year, new me? Pfft. New year, new camera? Hmm, maybe once the credit card has recovered from the beating it took before Christmas. Okay… new year, new year resolutions? That’s more like it!

    Whether you’re stuck in a rut, trying to break some bad habits, looking for some motivation, or trying to give your images a push to that next level, making a new year resolution about your photography is a great way to hit the ground running in 2023.

    Here on Digital Camera World, we’ve each been making resolutions regarding our own photography. So here are the seven resolutions we’ve pledged to make starting on January 01…

    If less is more, just think how much MORE would be

    James Artaius

    Editor

    As a portrait photographer, for 90% of my shots I crank the aperture as wide as it will go and let rip. It makes sense with a lens like the Canon RF 85mm f/1.2L, which was put on this earth to take photographs wide open and blur the background into a syrupy smush. But when I’m doing my everyday photography, I need to get out of the habit of shooting everything at f/1.2 or f/1.8 (unless the light demands it, of course). I want to stop being so stingy with depth of field and start being greedy with it instead!

    Actually having my camera on me

    Lauren Scott

    Managing Editor

    As a photographer who now writes more about photography than actually taking any pictures, I’ve become so out of the habit of taking my camera with me unless I’m “at work”. They say the best camera is the one that you have with you, but while my iPhone 12 is a handy camera phone to have in a pinch, it’s no match for the quality of my Canon EOS R6. 

    Given that I mainly use this full-frame mirrorless camera with the cheap, cheerful (and compact) Canon RF 50mm f/1.8 STM lens there’s really no excuse not to take it out with friends, in a new city, or just walking the dog. My new year’s resolution is to rediscover the joy of walkabout photography because, to my mind, that’s where the real creativity happens.

    Likewise, my new year’s resolution is to take a camera with me wherever I go, be that film or digital, just so that I have something to always capture the moment – not just on my phone!

    Digitizing my photo archive

    Chris George

    Content Director

    When I fully switched to shooting digital around 18 years ago, I spent a long time scanning thousands of my then-favorite slides and negatives from my archives. But now, a couple of decades on, I wish I had not sold my film scanners – as I now want to go back and revisit some of the images that did not make the cut last time around. Last time it was more about which would I could use in articles, or sell through image libraries. Now it will be more about reliving memories of people and places.

    Shoot on auto to shoot more

    Gareth Bevan

    Reviews Editor

    Working as a fashion photographer for years I am far too concerned about the settings I am using for my photos to get that creative look that I’m after. This bleeds into my everyday photography; I often spend too much time fussing over setting up my camera for simple shots where creativity really isn’t essential. From now on, I am going to make an effort to embrace the auto – I am going to learn to flick my camera into auto and let the camera take a perfectly serviceable photo and save myself a headache and a lot of time. Auto… who has to know?

    Shoot more medium format film and invest in a light meter! 

    Hannah Rooke

    Staff Writer

    As a mostly digital photographer, I’ve always been able to rely on getting the exposure correct by checking in the camera – not exactly a luxury you have when shooting film. Last year, I was very lucky to pick up a Pentax 6×7 for a very good price but have since only used it once. It feels like such a shame to have such a beautiful camera just sat on my shelf. As the film and developing costs are so expensive, I need to bite the bullet and invest in a light meter – I’ve always thought that they’re complicated to use but, in reality, I just need to get to grips with it so I can start shooting more film confidently and accurately!

    Take more photos

    Beth Nicholls

    Staff Writer

    I take at least three photos a day without even trying using my Samsung smartphone, whether it’s of my dog, a grocery list, or a cloud outside that I thought had an interesting shape. But I very rarely take photos on my camera any more, and it’s a shame. I’m also especially bad at sharing images that I’ve taken and edited on social media or posting to my website. My new year’s resolution is to take and upload more photos, and find my passion for photography again. 

    To buy a camera

    Ben Andrews

    Lab Manager

    Just one proper dedicated camera to call my own. Earlier in the year I sold my trusty Nikon D5500 to help fund another project, leaving my Xaomi Redmi Note 9 Pro phone to cover all my photographic needs. Though good enough for most situations, the phone’s primary wide-angle camera (and the only one of the quad-cam array worth using) is a terrible focal length for portraiture – and with no image stabilization, low light shooting is tricky at best. Even tasks as simple as photographing products to sell on eBay can be a hassle, as the phone’s limited dynamic range and overzealous image smoothing makes it difficult to capture subtle item imperfections. So which new camera to choose…
