smooth out colours
#10
Necro as this is still a problem and ppl dont seam to understand what im talking about, the problem isnt that the transitions are visible, the problem is that the transitions even tho its going from lighter to darker is not perfect transition and have different shades and completely different colours sometimes in between rather the just going to the next shade, 132435 instead of 12345

(i have no real idea if its shades or colours, since the colour is affected by the shade but its the shading which is the problem, so i just viewed all of this as base colour and the different shades was due to the shading, which might be wrong since in some images the colours repeat even when the tone of the image changes (last 3 pictures), which all makes this confusing in itself)

High contrast (not sure if you can actually use my pictures for self study as they are screenshots)

After studying other pictures across the internet, iv noticed it look more like shading then actual colours, like there is shading ontop of shading ontop of shading, rather then different colours. So when two shadings overlap it gets darker. 

Which is quite obvious at a smaller size of the same picture as above.

I think it looks like this is because there are different shadings from different directions that are mixing. Im not good at explaining bool mathematics but that's basically what it is, one shading is added to the other shading but they also decrees as they go along. 

Like if you have one shade going from the top and one from the left, the top-left most pixel is going to be the darkest, and the bottom-right most pixel the brightest. and now you make the shaders not square, or just towards each other and one of them is shifted, and they start to do unexpected stuff, like creating lightspots since one of the shadings lower in value before the other etc. 

The left of the picture above is a example of 4 shadings overlapping. One is the dark spot on the left which dies out rather quick, one is in the same place but goes a little higher and more vertical, one from the top that covers pretty much everything, and one that starts in the middle of the picture and goes from the top right to the bottom left and dies out very quick, dropping value only 3 times (4 shades). And this is only in this screen cap alone, these could continue across the whole picture mixing with other shaders. Like how smaller functions form a larger one.

What is causing this in the first place i dont know, since iv checked a few formats and from different places, and its all the same.

some images behave differently, as said in the beginning, here is a screen cap of a picture which just go from light blue to darker blue

Here its the same but with high contrast

and with one of the colours selected

There is no reason why there should be this much of the same colour, when it's supposed to change colour.

This might just be because of the algorithm of how you store a image, and might go unnoticed by the masses, but as some one who care about detail its extremely annoying and ruins pretty much every image.
