Ruby throat hummingbirds of course. Last year I saw some of Tim K images (posted on N&W) of hummers shot at 3200 ISO. In the past I avoided shooting hover hummers higher than 1600 ISO or f-stops below f6.3. My previous attempts the last two years were utter failures because of my lack of confidence straying away from what felt comfortable and/or I just did not have the right combinations.
I am posting five images taken over the last several days. I want to also mention I don't shy away from the darker images when they present themselves. The dynamics of light and dark in combination can coexist in the same image. Rembrandt did it best.
I would appreciate any and all CC.
What causes the blotting/bloching in the bgs of these shots? They are not on the images prior to posting on FM or when printed at 11x14in
Very nicely done Ted. I wonder about the circular and splotchy patterns that are most pronounced in the first two and some of the last few. My concern about shooting at high iso is much less about what they look like shared on a computer but blown up to any significant size. But certainly, the advancement in high iso and noise reduction software that is non destructive makes those concerns much less founded.

Interestingly enough Eric, the blotches, circular patters are not present when printed at 11x14.

Huh? That's quite interesting indeed...funny that it would show up on the computer version but not printed. But knowing that may be the case, I might be much more likely to try to "up the ISO' on my shots as well....thanks for sharing that bit of information which is much more than a little helpful!

Ted I believe what we see are just tone brakes, resulting in a series of colored bands rather than a smooth, continuous gradient. It is also known also as posterization, or banding. It only happens on smooth areas with no detail.
They are very annoying and distracting. One of the causes is stretching the histogram too much in PP.
Apart from that your images look fine

I don't think this is banding. You're seeing jpg artifacts.
I usually look at the pictures on FM using a retina display iPad. It's easy to pull and pinch the pictures so they instantly blown up. This has the advantage of quickly seeing the artifacts and other things like its easy to see pictures that are oversharpened and those where people leave the noise in the bird but take it out of the background. Such pictures are very evident.
All your pictures in this thread show the artifacts with #2 showing it the least, probably because its lighter. I started to check your long thread with 25 hummers and stopped after checking about half of them. They all display the artifacts.
You're not seeing them in prints because you're probably keeping the full resolution of the picture. Depending upon what your printing them on and the dpi, a 11 x 14 might be at full resolution for a full frame picture with no upscaling with 15 mp.
When you save the jpg for the web, just increase the size of the compression. In other words, make the file bigger. I believe that is the problem. You are compressing the .jpgs too much.
It is #1 that is #1 for me sir, lovely!
Sometimes the resultant BG I have found will do that if you have 'missing information' showing in your histogram, areas in the histogram will have blank areas showing.

Ted- The Peanut Gallery thinks these are swell pictures, and some are sweller than others.
The first shot is the swellest of them all. That's partly because The Peanut Gallery likes pictures to be sharply focused.
The rest of the reason is that it's just a real purty picture .
