The Canon EOS R3’s Megapixel Count Revealed By EXIF Data

The Canon EOS R3's resolution revealed by EXIF data

For months, Canon has teased the upcoming EOS R3 and its groundbreaking features, but – as with the release of the EOS R5 and R6 last summer – the company has remained silent regarding resolution. 

Speculation and rumors have abounded, at times suggesting a 30-megapixel sensor like the Canon EOS R or even a 45-megapixel sensor to match the EOS R5. But thanks to Canon Rumors, we now have what appears to be a definitive answer:

The Canon EOS R3 will be 24 megapixels.

This specification is backed by significant evidence coming out of the Tokyo Olympics, where the Canon EOS R3 has made an appearance. First, Canon Rumors reported “multiple mentions, likely from people in and around the Tokyo games, that the resolution is ‘closer to’ or ‘around’ 24 MP.” This 24 MP rumor was followed by an EXIF data report showing 6000px by 4000px (i.e., 24 MP) dimensions on EOS R3 Olympic files.

Yes, it falls short of the lofty resolutions suggested above and will slot in behind several of Canon’s top mirrorless cameras, but 24 MP is certainly respectable and hardly unprecedented. After all, the EOS R3’s closest DSLR sibling is the Canon 1D X Mark III, Canon’s flagship DSLR, which features a “mere” 20 MP. And “fast processing, low megapixels” has long been the name of the game for sports-focused models, where high-resolution sensors threaten continuous shooting speeds, camera buffer depths, and more.

A 24 MP sensor also assures superior noise performance over higher-resolution models like the EOS R5; the lower megapixel count (and consequently larger pixel size) combined with Canon’s new backside illuminated sensor technology should be a sight to behold.

At present, here’s what you can expect from the EOS R3:

  • A fully-articulating touchscreen
  • 30 frames-per-second shooting (using the electronic shutter)
  • In-body image stabilization
  • 4K video
  • Eye Control AF
  • Top-notch weather sealing
  • Dual card slots

While pricing information is yet to be released, don’t be surprised if the EOS R3 surpasses even the Canon 1D X Mark III, which debuted at a whopping $ 6500 USD.

Fortunately, you won’t have long to wait; Canon Rumors promises an official announcement in September, and I’d wager that the camera itself will ship before 2021 is out, if not significantly sooner.

Now over to you:

What do you think of a 24 MP EOS R3 sensor? Is the resolution disappointingly low? Is it just right? Too high? Share your thoughts in the comments below!

PhotoStatistica is a macOS app for visualizing the EXIF data of your photos

09 Jun

Looking at the metadata for a single image can be helpful, but sometimes you need to get a more macro-level view of your work. Enter PhotoStatistica, a new macOS app that parses through the EXIF data of your photos and breaks it down into infographics and statistical analyses.

The app is developed by Bristol Bay Code Factory and is designed to offer a more visual representation of how you shoot. This information can be used to not only improve your photography and better know what settings you might need to gravitate towards (or avoid), but to also guide you in purchasing future gear. If you find out you tend to shoot around 135mm with your long-range kit lens, it might be worth picking up a 135mm prime; if you tend to shoot at high ISO ratings, maybe you should prioritize low-light capabilities with your next camera or pick up an F1.8 or F1.4 lens.

PhotoStatistica supports JPEGs, TIFFs, DNGs and most proprietary Raw formats. It can sort through nested directories and seek out images or directly look through Capture One Pro libraries or Apple’s Photos app libraries. Once PhotoStatistica sorts through the EXIF data of the images you’ve selected, you can use the options at the top of the app to visualize the results using bar, pie and pivot charts. You can even export all of the data in CSV format for save the current EXIF set for analyzing at a later date.

PhotoStatistica is currently available to purchase in the macOS App Store for $ 2.99 / £2.99 / €3.49.

Leaked EXIF information suggests Leica is working on a 41MP Monochrom M10 camera

02 Nov

Leica Rumors has shared a screenshot of EXIF data from what it claims to be a Leica M10 Monochrom model. The leak suggests past rumors about a 41MP sensor may have been correct; the EXIF data shows a 40.89MP resolution at 7864 x 5200, as well as a 50mm focal length and 12500 ISO.

The new EXIF data leak follows a report that Leica Rumors published in late August that claims the camera will feature the same body as the Leica M10 model and that it will launch with a limited edition ‘celebrity’ variant. The speculation about an official launch in September didn’t pan out, however; the model remains unconfirmed and it’s unclear when Leica may release it.

Improve Your Photography by Learning How To Use Exif Data

03 Dec

The post Improve Your Photography by Learning How To Use Exif Data appeared first on Digital Photography School. It was authored by Kevin Landwer-Johan.

Whenever a photo is taken with a digital camera, data relating to that photo gets stored with the image in what’s known as the Exchange image file format (Exif).

Knowing how to use that Exif data can help you gain insight into the camera settings of both your own and other people’s photos. Seeing what settings worked well together in a great photo (or didn’t work well in a bad one) can help you improve your photography skills.

Data About Data

The Exif data is what’s called metadata (data about data). Some data is more significant and useful than the rest. Within it you’ll find the information you probably know already – camera make and model, image dimensions, copyright information, etc. But you’ll also find information about the exposure, whether or not the flash fired, metering mode, distance to subject, and plenty more.

You can view the Exif data on your camera, on your computer, and on photo sharing sites such as Flickr and 500PX.

Here’s a screenshot of the Exif data being displayed in Adobe Photoshop after choosing ‘File Info...’ from the ‘File’ menu.

To view this information in Windows right-click on the image file and select ‘Properties,’ then select the ‘Details’ tab.

If you’re using a Mac, open the image file in Preview, then select ‘Show Inspector’ from the ‘Tools’  menu and select the ‘Exif’ tab.

Note: Adobe programs create a file with the same name as the image but with the extension ‘xmp’. This stands for Extensible Metadata Platform and contains the Exif data for the image.

As you can see, the EXIF data includes all the information about the exposure. My camera was set to manual mode. My shutter speed was 1/320 sec, the aperture was f/2.8, the ISO was 100, and I used my spot meter. It also shows that my flash fired.

In these examples, we’re looking at data from the RAW file. But the data is also stored in other file types such as JPEG and TIFF.

About the only thing it doesn’t tell you is whether a photo has been manipulated during post-processing.

How Is This Information Useful to Beginner Photographers?

When you first start out, and you’re still getting used to your first camera, the Exif data can help you learn. If you took a photo that didn’t turn out the way you thought it would, the data may show you why.

For example, seeing that the shutter speed was 1/4th sec will help you understand why your photo was blurred. To shoot at such a slow speed you need to use a tripod to avoid camera shake.

And seeing an aperture setting of f/16 will help you understand why so much of your image is in focus. You could then look at the Exif data of an image where more of the composition is out of focus to see what its aperture setting was.

Use Exif Data To Make Comparisons

The Exif data can also help you compare images you’ve made. Looking at the lens data can help you understand when it’s best to use that lens. Compare the same aperture setting on two different lenses. It will help you learn more about depth of field.

Comparing the same image shot with two different focal lengths is also a useful exercise. These three photos were taken using different lenses (as shown in the Exif data).

Analyze and Anticipate

Analyzing the Exif data of your photos can help you plan and improve future photo sessions of the same subject or situation. Studying the data on photos from an annual event will give you insights into what you did well and where you can improve.

The Hmong people in Thailand, Laos, Vietnam and other countries (including the US and France,) hold awesome New Year festivals. The celebrations include various sporting competitions such as kart racing, crossbow shooting and top spinning, which can all be challenging to photograph.

So before I go to the festival each year I look back at photos I’ve made previously. The Exif data from these images reminds me of the settings I’ve used in the past. When I arrive I know which lens will give me the best photos for each competition, and what shutter speed I’ll need to capture sharp action in the kart racing.

Analyzing data from photos of subjects you don’t photograph can also be helpful. On websites such as Flickr and 500px the Exif data is often displayed alongside the photos, and so you can use it as a reference. When you’re photographing new subjects, especially ones that require special camera settings, look at the Exif data of other people’s photos. It could save you a lot of time and stress.

Conclusion

Making the most of the tools you have will help you become a better photographer. Next time you wonder why a photo worked (or didn’t work) so well, take a look at the Exif data. You may be surprised what you can learn.

Do you use the Exif in other ways? I’d love to hear about it in the comments.

NameThatLens is a cross-platform tool for adding EXIF info to vintage manual lenses

03 Jul
Erwan Hesry/Unsplash

Do you ever shoot with older lenses that aren’t capable of transmitting metadata to the camera when you shoot? If so, you might want to try out NameThatLens, a cross-platform program that simplifies the process of adding lens information to photo files.

NameThatLens was developed by Georg Fiedler, a photographer who often shoots with classic and vintage manual lenses. ‘Unlike with a modern auto-focus lens, a digital camera has no way of determining what lens was used to take a photo, or indeed what the aperture and focal length were set to,’ says Fiedler in the NameThatLens announcement post, adding ‘it is therefore not possible to record this metadata in the image RAW file or processed JPEG file.’

Fiedler says he came across the LensTagger plugin for Lightroom, but felt limited, because he often uses other post-processing programs such as Darktable. So, he set out to develop his own version—one that would work across Windows, MacOS and Linux computers. The result was NameThatLens.

In Fiedler’s own words, ‘NameThatLens, in its current form, is essentially a GUI for the wonderful ExifTool by Phil Harvey.’ But the goal is to turn it into a standalone program ‘in the near future.’

Currently, you can create author profiles, lens profiles and image parameters. The author profile tab of NameThatLens adds artist and copyright information to the images, the lens profile tab is a collection of the manual lenses you shoot with and the image parameter tab lets you set the aperture, focal length (if it’s a zoom lens) and other details.

As of writing this, the following formats are tested and proven to work with NameThatLens: JPG, ARW, ORF, and RAF, although Fiedler notes that most any image file you throw its way should ‘theoretically’ work.

Fiedler notes that the program is in Alpha phase, meaning there’s still work to be done and bugs to squash. However, if you’re fine with possibly running into a few snags, you’re free to download it and take it for a spin. Currently, the MacOS and Linux versions are available, with the Windows version set to be ‘released shortly.’

You can find out more information on NameThatLens, complete with installation instructions on Fiedler’s NameThatLens webpage.

App review: Full Frame is a quick, easy JPEG viewer, EXIF editor

28 Jun

Full Frame is a Mac-based image viewer, photo importer and metadata editor that centers around an incredibly clean and intuitive user interface. Released by California-based Inland Sea and available now in the App Store, its potential to speed up one’s workflow caught our attention.

Of course, there are a lot of different photo viewing, ingesting and sorting programs available on market, many of which are geared toward casual users. Full Frame, on the other hand, is targeting more toward high-end users like photo enthusiasts.

In Use

Having spent some time trying out using Full Frame in my own workflow, it seems its closest competitors are Photo Mechanic, a time-honored program with a cult-like following from photojournalists world-wide, as well as Adobe Bridge.

Unlike Adobe Bridge, which I find frustratingly sluggish and cluttered in design, Full Frame comes across as exceptionally lean in terms of speed (except when working with un-supported Raw files) and design. It has much more in common with Photo Mechanic like quick startup and image load times. Of course the spectrum of its functionality is much more limited than that of Adobe Bridge.

I took Full Frame for a spin while sorting images to post to one of my personal sites. Specifically,  I used it to move and rename selects from one drive, to a folder on another.

Once you have Full Frame fired up, users simply select the source folder and destination (assuming you are copying files) in the upper-left of the screen. The above screenshot represents the entire window when the program is open. There is literally nothing to get in your way of viewing images and deciding which to keep and which to trash.

To select an image to copy, simply click on it and a checkmark appears. Alternatively you can select all by hitting ‘Command A’ and uncheck the ones you don’t want. In the upper-left portion of the window you’ll find a slider to zoom in the grid view as well as options to view metadata and delete files from their source.

With your mouse hovering over an image, a small plus sign will appear in the upper left of the photo. Click on it to expand the view. Once in the single image viewer, users can use the slider at the top to zoom the image in and out, to check for critical focus. Unfortunately, when zooming in and out, there is no display of the percentage you are zoomed to, unlike in Photo Mechanic.

One of the best features of Full Frame is the metadata/EXIF viewer. It offers an incredibly detailed list that goes above and beyond what a lot of other programs show, including Photo Mechanic.

Users can also add EXIF info to any imported files from within the preferences panel. One thing I’ve always really liked about Photo Mechanic is how simple it is to add copyright warnings and contact info to my files. In Full Frame, it is just as painless. From within the preference panel users can also assign rules for renaming files on import, which is very handy. 

In many ways, Full frame comes across as a utilitarian program, built to accomplish several specific tasks related to moving and organizing images. However it also doubles as an outstanding way to show off your work to clients, friends or families. The grid view is frankly gorgeous, and once in the single image view, users can simple use the arrow keys to move from image to image. It also starts up very fast, which is a plus.

Things to consider

While I found a lot to like about Full Frame, there are some things to consider before purchasing it: First and foremost, despite the claims of Raw support, I found numerous files, from varying manufacturers, to be unsupported. For instance, Raw files from the Nikon D750 are unsupported, as are those from the Sony a7 II. However, if you have Raw+JPEG files, load times will slow significantly but you can at least view and import your images.

This is really quite unfortunate. Sure, app updates could bring about Raw support but who has time to wait around? On the other hand you could always covert to DNG first, but if the whole point of this program is to speed your workflow, that also makes little sense. Photo Mechanic on the other hand does not have this problem, it can display a JPEG rendering from any Raw file, and loads quickly regardless.

Another beef I have with Full Frame is that there is only one option for sorting/rating images. In Photo Mechanic and Bridge, there are numerous ways to rate and sort images. For instance, when choosing my selects, I first do an initial sweep and check mark all of the ones I like, I then assign color or star ratings until I’ve got the images sorted down to a manageable amount.  At that point I copy the selects to a separate drive to be imported into Lightroom for processing.

The Takeaway

Full Frame is not a program that can do it all, but the things it can do, it does well. If you need a quick, easy way to view JPEGs or edit/view EXIF info, it might be your cup of tea.

Full Frame is an outstanding option for photographers seeking a powerful EXIF viewer/editor or a quick and easy way to import and rename files. Its spotty Raw support is the main thing holding it back. But at $ 30, Full Frame is a major bargain compared to Photo Mechanic, which will set you back $ 150. It is also a much faster way to quickly view and sort JPEG files than Adobe Bridge.

What we like:

  • Intuitive user interface
  • Very clean, simple design
  • Powerful EXIF viewer and editor
  • JPEGs load very quickly
  • Can be used to import, sort, batch rename files
  • Support for video files

What we don’t:

  • Despite claims of Raw support, many Raw files not supported
  • No percentage shown on zoom slider
  • Not as many options for rating photos as competition
