Strange lines

Radub85
Hello, i just reinstaled windows and photoshop, and now when i try to save a png (that looks ok) into a jpg, the jpg photo has some strange grey lines some wider some thinner. Please does anybody has any advice? Thank you.

Are they straight lines or lines that contour with the gradient change in light? Contoured lines are called BANDING and you can find various tips on Google for removing them. Very frustrating, though.

Since you reinstalled windows I am wondering if it's possible there is an issue with the graphics interface. You can try viewing the image on different computers and seeing if the lines "travel" with the image. If not then you will need to adjust your monitor settings.

Thank you for your answer, yes there are lines that appear where there is gradient...but in the mean time i had found another way...i save the files from adobe bridge and they are ok, if i save them in photosop, paint or any other software...those lines appear.

Hello,

I've also had problems with gradient banding but in my case this effect is accentuated also because of my monitor calibration.
I usually solve this with blur (not to much because is possible you will get some distorted pixels), noise and after that i downsample a little bit the image.
Even if i reduce them i still see the banding on my monitor at home, but if i check the same image on another monitor, they look fine.
