are you suffering from a bug that when you take the picture it's perfect clear, but when you tap to see it, the system puts like a green hue on it?
I updated to amber and now I'm suffering from this =/
Hi Andre!
It is not a bug. I'm sure you mean thing that happens when you view photo from that small preview image top left corner. It momentarily shows image how camera sensor saw it before software added post processing in to it. If photos would be saved like it appeared on your screen before you take shot, those would look completely bad. What you see momentarily is RAW image snapshot straight from sensor without any post processing. This phenomenon is best seen when you are shooting in very low light and then look in to that preview image and you see how photo is momentarily filled with noise before post processing cleans it out. You see that same noise from screen before shot and that image in your screen is actually RAW image your camera sees before any post processing.
Screens pixel density is over 300ppi and it hides all noise from those RAW images and making them look sharper but those would contain very much noise in them. Post processing ads colour corrections and noise reduction which makes photos look different compared what you see from screen before shot. If you go straight to camera roll, you see processed images without that shift in colours.
Image doesn't look like in real life from your screen before shot by the way. Try this out comparing colours from what you see from screen before shot and look how it is in reality. Then take shot and look how colours are after processing. Yes, those are correct after that most of a time.
Sensors in phones camera are very small and that means more noise and therefore more post processing, which leads to poorer image quality. Sensors in actual cameras are very big compared to phones and those big sensors leads to low noise, accurate colours and less processing needed which means high image quality.
Shift between preview image and processed image depends completely how good lightning conditions shot is taken. In good sunlight there is quite little need for software to correct it. In those conditions you see almost no shift between preview and processed image, since very little processing is applied. Low light conditions needs lots of noise reduction and colour correction, meaning noticeable shift between preview and processed image.
Hope this helped :smile:
