Looking for blue- cool lighting

[Asylum Steve]

First of all, welcome to the site and the forum. For what it's worth, I think your shot looks great as is, but as one who gives much of my work cool tones, I can understand you wanting to get that effect.

Whether you're shooting film or digtital, there are many ways to manipulate the color temperature of your lights and scene. You can filter the light, you can filter the lens. With film you can mismatch the film color balance with the light color balance. You can cross-process the film.

With digital, the choices multiply dramatically. The most obvious is to mismatch the White Balance in the camera to achieve a cool toned image. Or, there's photoshop...

I'll have to disagree a bit with Rere15 and say I see nothing wrong with using photoshop as your color adjustment tool for any image anytime. That's what it's for.

To me, it makes much more sense to concentrate on lighting ratios, tonality, exposure, and subject posing and emotion in your studio session, then worry about precise color balance in post-production.

If you shoot RAW, you can make your WB adjustments in the ps converter and not have to make any more edits. Or you can use any of a dozen color editing tools and filters and create something like what I did here.

I simply added a blue layer above the image, changed the layer blend mode to color, then changed the layer opacity to 50%. It took me less than 30 seconds...
