Converting a photoshop picture to another format

[samygero]

Hello everyone!

I have processed a picture with photoshop and I would like to have it printed on a poster.This picture has different layers I've worked with.

Unfortunately when I convert it to another format jpg, bmp, or even png the colors and the sharpness are a bit degraded or altered, even with the best quality.

Can anybody tel me how I can overcome this inconvenient?

I don't know if it matters but I work on a macbook I bought 1 year ago.

Thx for any answers

flatten it.
try an uncompressed tiff. many image types compress the image which is likely why youre seeing degradation.

whats the resolution?

What color profile are you embedding in the saved image (jpeg, png or whatever)?

So it is quite large image, pixels are 2816x2112,

when I save the image there is an option that says Embed Color Profile : sRGB IEC61966 - 2.1, and I choose off courde maximal quality.

In bitmap no such option is possible.

The resolution of this picture is huge because I want to be able to print it on a poster without detail loss.

Simple solution: Don't use bitmap.

For best quality use JPEG at highest quality (although you state this did not give you great results) or use TIFF, be warned they can be large files though
