I think your artistic decisions in this image are fine, and it is a worthy effort, but I also think that is exactly why Shutterstock rejected your image: they don't buy art. I would suggest that Shutterstock is interested in images that can be utilized commercially, where the subject is critical to conveying whatever the client wishes. Should the client wish ...

Doing an edge detection, this is where your image is sharp: If I draw a rectangle around it, it is 475x514 pixels, or 244kpx² out of 4600kpx². That's just 5%! Even for a picture with blurred background, my expectation would be more like 30%. An acceptable image (just considering sharpness) could be For the above picture, I still see a lot of room for ...

At least as of a few years ago, there was no "algorithm". The only automated reason for a rejection, when I was there, was submitting an identical image to one already on the system. Everything else was done by trained humans. I don't believe it's changed terribly much in the intervening years. This isn't a saleable image by Shutterstock standards, ...

Looking at the EXIF data in the posted photograph, i.e. extra information also stored in the image file, such as camera and lens model, and camera settings, I can see this setting: Exposure Bias Value: -5 I assume that "Exposure Bias" is what is also called "Exposure Compensation". I.e. you tell the camera, that this should be darker or brighter than ...

Several possibilities: In the examples shown, it could be a problem with the subject. The center of the picture is a rather fuzzy plumage for the dove and sharp lines for the white-eye. Your 55-250mm is not so sharp at the long end. Decent lens, but not built/checked to stringent specs like a L series. Only way to tell is to try another lens. Your camera's ...

I'd change the CR2016 anyway* - they're only about a buck even at full retail price - & see if it improves. Also give the contacts a quick spray with contact cleaner or 90% isopropyl & allow to dry fully. If it doesn't improve, then you're probably in for more costly repairs. *It's almost impossible at consumer-level to measure a voltage under ...

The lens hood you bought is for the EF 18-135mm f/3.5-5.6 IS USM, but the standard kit lens supplied with a Canon EOS 7D Mark II should be an EF 18-135mm f/3.5-6.3 IS STM. Though the names are very similar, they are two different lens designs which share the same focal length and aperture ranges. If I am not mistaken you will need the EW-73B, check also ...

whether lens could be repaired without loosing big amount of money? Whatever the damage, repairing the 18-55 almost certainly isn't worth it. People upgrading sell them for not very much, just get a new one.

Bird photography is challenging, because birds are fast-moving subjects. Action points for you (based on my personal experience): Make the shutter speed as fast as possible Because of that, you will be tempted to shot with a maximum aperture. Don't take pictures on wide-open aperture, however. Close it a bit (for 1 stop at least). Lenses are softer wide-...

The black obstruction looks like a detached aperture blade. This is a seriously damaged lens. Repairing it would at least require it to be dismantled and the aperture blades replaced. Possibly there is even more damage. As the lens seems to be on the cheaper side, it seems to be more economic to replace it - maybe with a used one from one on the various ...

Your camera does not have the option to disable Exif. I know of no camera that has the ability to enable and disable the saving of metadata. Some old cameras from the 1990s do not save Exif metadata. Some phone camera apps also do not save Exif metadata. This is usually considered a bug.

The maximum file size on FAT32 is 4GB-1. I'm not familiar with the original 7D (I have a 7D II), but unless the firmware is programmed to record to multiple files, switching to a new file automatically when you hit the 4GB-1 limit, that's going to be your limit. Perhaps recording in one of the lower resolutions will allow you to go longer time-wise, but the ...

Others have already pointed out it is pretty much impossible to do in-camera unless the camera is a smartphone or really old and already does not record EXIF it at all. Now for a solution that's workable and might not be such a hassle. I presume you own a computer and do not just go to your customers, SD card/flash disk/camera at hand. If so, there are very ...

Since the adapter moves the lenses further from the sensor, I’d imagine that the coverage of the lens would be larger, and that the adapter or body alters focus to compensate. Is this thinking correct? No, because the adapter doesn't move the lenses further from the sensor in an RF mount camera than the lens is when attached directly to an EF mount camera. ...

I am sure the product specification page has not been updated since the launch and which is why it is mentioning the camera bodies available at around that time. There is no reason for the rf-ef adapter to not work since they communicate via the same protocol/mount. If that would have been different for each camera (not consistent across all cameras with the ...

Better lens and as cheaply as possible don't go together. The cheapest possible lens is always the one you already have. If you really want to buy something to improve your landscape photography, buy a good tripod with a solid head and a way to release your shutter remotely. Or take a course in landscape photography. These will do far more to improve your ...

When I look closely, I can see scratches on your front element. There is an old trick to deal with scratches on the front element to prevent lens flare. Just take some black paint, or black marker, and fill in the scratch with black, then wipe off the excess. The tiny black line will not be visible in the final image. Less light will be reflected by the ...

I seem have found the culprit, my single coated 67mm Hama UV filter. I put it on as some point between these two pictures and didn't think it could be the cause because I have never had issues with filters before with any lens. Here are before and after pictures with and without the filter, both at 400mm f/6.3 1/400 ISO250 on my 70D. And 100% crop ...

I could see their point if it was a human rejection - just wanted a bit more of it to be sharp. There's really only a couple of the buds close to being properly sharp. I could see them wanting at least half of the one stalk, at minimum. I'm not seeing any noticeable noise, but the bokeh looks 'edgy'. Perhaps a little chromatic aberration in the bokeh too. It ...

The EF-S to RF adapter is only possible because of the very short Flange focal distance of 20mm of the RF mount compared to the 44mm of the EF and EF-S mounts. The adapter places the EF-S mount lens at it’s native 44mm distance from the sensor, so the image is no larger, and there will still be severe vignetting with most crop lenses. Canon RF mount cameras ...

Under Linux you can simply install gphoto2 and v4l2loopback-dkms (package name might vary). Then simply run: sudo modprobe v4l2loopback exclusive_caps=1 card_label="GPhoto2 Webcam" Find out which webcam device it uses, in my case it was /dev/video2 and run: gphoto2 --stdout --capture-movie | ffmpeg -i - -vcodec rawvideo -pix_fmt yuv420p -threads 0 -f ...

2020 brought us (among other things) the EOS webcam utility.

When that product specification page was written, the EOS R was the only RF mount camera available. The RP, R5, and R6 hadn't been introduced yet. The same EF→RF adapters that work with EF lenses for the EOS R and EOS RP will also work with the newer R5 and R6. In the EOS R5 Specifications document the following two entries are listed as Compatible Lenses: ...

The correct answer totally depends upon the specific lens and also upon the manner in which you desire to use it. When using a lens on a tripod, some lenses require you to turn IS off, some do it automatically for you, and others actually have IS modes specifically created for tripod use. The last category includes Canon's latest Super Telephoto series that ...

As you have found out, filters can cause issues. Every time light hits a reflective/transparent surface some light is refracted through the surface and some light is reflected off of the surface. The coatings on lenses and filters are meant to suppress those reflections. Single-coated is better than uncoated, and multi-coated is better than single. The light ...

Here are a few suggestions that will help you for future submissions. Image Caption / Image Title The correct description plays a huge role in the image being accepted or not. An image such as this, needs a caption such as the following, or something to this effect “A single in focus strand of purple lavender against a sea of blurry and out of focus purple ...

This is a coupled rangefinder camera, so the lens attached to it will be rather integrated into the camera mechanics - no chance to hack that camera into anything that can usefully work with fully interchangeable lenses. Wide angle converters or teleconverters that can be adapted to the filter thread would potentially work, as long as they do not shift focus ...

The image appears, first, to be underexposed; that could be a camera problem (low battery or poor battery connection, failing meter system, failing shutter control circuitry) or due to sensitivity loss from poorly stored and/or expired film. On top of that, there are the light areas in the upper corners of the print (which would be the lower corners of the ...

When using an EF-S lens on any of the current EOS R series of cameras, only the center 22.5 x 15 millimeters or so will be used to contribute to the image. This is because EF-S lenses only project an image circle large enough for a sensor with a diagonal of around 27mm. That's a linear reduction by a factor of 1.6 from the dimensions of a 36 x 24 millimeter ...

I own the Canon Pro 1000. Short answer: Don't buy the printer for this scenario. Use a printing service instead. The Canon is designed to be frequently used. It uses pigmented ink which don't take long periods of not being used too well. It even shakes the cartridges before each print run. If the printer is kept plugged in, it will clean itself from time to ...
