Posterization never causes weird colors like blue/yellow to appear Canada Goose Coats On Sale where they were not.

Whatever is causing the aberration above the lips is canada goose outlet unicorndesigns.ca uk definitely not posterization.

That is an interesting article about lossy compression and i enjoyed reading it, but I don think that is what is going on with canada goose outlet store uk your image.

I don it think chromatic aberration, because it has a random pattern

I not 100% convinced it is random. It looks like it is most appparant along high contrast areas.

Plus, the canada goose outlet black friday screenshot is from the very center of the canada goose black canadian goose jacket friday buy canada goose jacket sale lens

That doesn necessarily matter.

Longitudinal chromatic abberation is just as likely to occur in the center of the lens as anywhere else. Center vs. corner only matters for transverse chromatic abberation.

It likely chroma noise, but why would it appear at canada goose outlet in usa ISO 100?

There is always a certain amount of noise with canada goose uk outlet digital images canada goose coats both because of canada goose uk black friday read noise and technology and the fact that Canada Goose Parka noise is a real canada goose outlet store phenomenon and even if canada goose a camera was perfectly detecting every photo, the particle nature of light means images will look noisy until you collect enough photons. Then you got amp noise, thermal noise, and read noise on top of that before any processing or compression.

Noise would be visible everywhere, not just there. And anyway at ISO 100. There Canada Goose Jackets simply is no noise in that shot. (Color noise reduction is what [happens to] canada goose outlet reviews work for you here, not luminance noise reduction.)

Posterization would goose outlet canada mostly be noticeable cheap Canada Goose in smooth gradients uk canada goose (and it isn canada goose factory outlet and anyway at the raw file bit rate it not obvious that canada goose Canada Goose Outlet outlet uk sale you see any. I did indeed use color noise reduction in post canada goose outlet sale processing. I also got the same results with the moir reduction tool. Do you think the moir happened because I used an insanely sharp lens on crop mode? Or canada goose outlet parka would Canada Goose sale the moir still had happen if I shot in full frame mode, but be less apparent, because it was “zoomed” out?

I assumed posterization, because the compression algorithm on the a7 gives you a lossy sRAW file, not a 14bit canada canada goose clearance sale goose outlet jackets lossless RAW file. It an issue with a lot of a7/a7r photographers. Check out the first two pictures in this link. The first two images have posterization similar to my canada goose black friday sale unwanted effect.
