Bending problem

Hi, how you solve the bending problem? Please do not talk about noise and all the post stuff. I mean really, like you approach an image and work without bending?

I'm retouching a car and I'm repainting the doors and after 5-6 gradients there is bending everywhere. I hate this thing because some times it happens and some times not.

Re: Bending problem

It looks like you may need to work in 16bit.

Re: Bending problem

You can still get banding in 16 bit but it is significantly less of a problem than in 8bit.

Re: Bending problem

The broader the color space the bigger chance that banding may occur so working in 8 bit ProPhoto would be a bad idea.

Also if you're using Photoshop, make sure you zoom in 100%, or flatten the layers, the non 100% previews may show banding even though there is none.

I've also found that adding a bit of noise helps to create smoother looking gradients.

Here's a nice short article about bit depth and color spaces:
