AP - blend brushes as concentrical circles?

[resunoiz]

when making brushes "points" or similar with a blend brush, the blend seems like concentrical circles, is not smooth and linear. see the sample. same brush, same dimension in photoshop is way too smooth, you can't see passages from a hue to another.

 

there's a way to correct/attenuat that behaviour?

Have you tried to changing your Document's Colour Mode to RGB (16 bit) in Document > Colour Format?

[resunoiz]

yes, this is a 16 bit one.

the jpg comrpession made it lossy, but was in that format.

Thanks for confirming. Do you have Preferences > Performance > Dither Gradients enabled?

[resunoiz]

yes, I have

 PNG generally works better than JPEG for screenshots, especially where text is displayed, and the file size is often quite small. Cropping the image will also help to reduce the file size significantly.

The only thing that can be done is to add a Add Noise Live Adjustment Layer to the layer with the banding. Make sure you have Monochromatic selected and use the Noise slider to remove banding.
