Impossible to tell, since most pictures on the internet is run through some sort of Stupifying Filter (a Photoshop addon?).
People constantly post heavily compressed jpgs or portions of jpgs and go OMGWTFPROOF!!!
Well here's some news for them: ITS IMPOSSIBLE TO DO PROPER PHOTOANALYSIS ON A JPG!!!
What we want:
- RAW format (or TIFF)
- 100% crop (obviously to cut down RAW size, but a link to the original would be nice too)
And that's it, two little points. Ever seen it posted? I havent.
As an example:
Lets say you take the *perfect* shot of a UFO at point blank range, but the sun is behind it and when you look at the JPG, its all black. Well pooh.
It aint ever gonna be anything but black even with manipulation, cause JPG compression has decided its black, period. The information is lost forever.
With a RAW, you could try to recover that information and hopefully get detail out of the "black" zone, because RAW takes your picture at a much
higher dynamic range and totally without compression.
