After weeks of shooting, finally came up with a series (9) of keepers, of which this is my favorite.
Did some enhancements and it looked reasonably great...until I printed and got better look at last 2 inches of wing on the left. Any idea why that area is so badly pixelated??x? None of the other 9 images suffer from this...
I am sending the .tif of the raw (CR3) before any enhancements.
Specs: Canon R5 with latest firmware. EOS 100-400 IS Series II. M 1/8000, F5.6, AutoISO, electronic shutter, expanded focus area, Sandisk Extreme Pro CFexpress 128G card, shooting distance ~15'.
Anybody seen this isolated pixelation before? cause? correction?
Thanks and I continue to love the forum...

I don't see any pictures. I'm going to guess that if you're trying to post .tif files, they're too large. Either put them somewhere to download and send a link, or reduce them in size so that we can at least see them, even if you have to make jpegs out of them. I think that the latter is better for a discussion where everyone can see what you're talking about at the same time.

Output the files as JPEG and attach and store.

The issue is clear in the wing tip on the image left and somewhat on the other wing too. Are you saying this arrived during the image processing or is present in the initial RAW from the camera? If in the original, please confirm, as we might be seeing 'shutter roll' when shooting shutterless on a mirrorless, especially the horizontal aspect of this phenomena.

Exists in the CR3 raw file still on card.
Someone else just mentioned that so probably the culprit.
Not too knowledgable on this so must catch-up...
Wonder if correctable in post?
Makes me want to reconsider using shutterless (electronic)...maybe not worth the few extra f/s...although really a game changer in getting these lightening fast little guys...
THANKS ALL...

I’ve been capturing hummers for a little bit now and from what I see in your shot, that’s just motion blur. Even at 8000 ss it can still happen.

For me, the blur on the wing tip reminds us how fast these wings move without spoiling the capture of the entire bird. Nice shot.

Nice capture. I tend to agree it's likely a case of motion blur.

I would agree. Although it looks pixelated, I think that's how the digital camera dealt with those fast wings.

Yep, just motion blur.

Those little wings move awfully fast....really really fast. Nice shot.

That's rolling shutter effect. Yes, it's a form of "motion blur", but it's made worse when using the electronic shutter. Use the mechanical shutter and that should solve the problem. Of course, your frame rate will be slowed a bit: "only" 12 frames/sec, instead of the 20 frames/sec that the electronic shutter provides. But, hey, 12 frame/sec is pretty damned fast!

If you want, Google "rolling shutter" for more info about it... how and why it happens, what can be done about it, etc. But basically, until image sensors are global... meaning that the data they capture is all read out at the same time, rather than "rastered" or read line by line from one side to the other... there is potential for rolling shutter issues with any electronic shutter. It can be reduced and minimized by some designs (such as stacked image sensors and sensors with very fast linear readout). Both fast readout sensors and global shutters exist, but they take a TON of processor power and require the camera to have extra wide bandwidth all the way through the image capture flow, from sensor to memory card.

Awesome with this lighting, color, and detail ⭐💚⭐
