Photoshop problem -- grainy photos

[Tom]

Hey guys,

I went to photoshop today and noticed this: http://i.imgur.com/wrnu6B5.jpg

As you can see the blacks are reallllly grainy. I have no idea why.

Here's my settings: http://i.imgur.com/adtm3rt.jpg

Curiously, when I go to save to web, in the previewer the colours go back to normal. Anyone know how to fix this?

Thanks! :)

What is the actual size? this normally happens when you scale too small.

What is the actual size? this normally happens when you scale too small.

It happens to all images with black but in the example it's a 43.35 x 28.9cm image entering a 105x148mm (A6) canvas.

What is your proof color set at? It's usually what decides the color photoshop shows you.

When you go to save it it could look better due to it saving as a diff color profile

I usually just keep mine on "monitor" so my colors look the sa3me outside of photoshop as they do inside. Anything other profile selected they look odd.

This was my first thought and unfortunately that wasn't the case.

The thing is if I open the image normally, it's fine. If I insert it into a canvas, that's when it cries and the blacks cry.

Can you post a photoshop file online so we can download it and check it out?

So I played around with a few settings in Photoshop and managed to fix it. I did a bunch at once so I'm not sure what fixed it exactly. It was a problem with the colour settings though.
