Color vibrance in Photoshop
March 16, 2008 by Daniel | Filed Under Uncategorized | 2 Comments
The Vibrance control in Adobe Camera Raw is really nice. It seems to boost the color of the less saturated parts of the image, giving a nice even colorful image. But it is not accessible directly from Photoshop. Here is a way to emulate the effect by making a saturation mask.
Notice how the bright flowers are unaffected by the saturation boost, while the green background and the rest of the image gets more saturated.
I have also made it into an action which you can download at the end of the page.

Why not to shoot black and white in camera
November 18, 2007 by Daniel | Filed Under Tutorial, Photoshop, Photography | Leave a Comment
Most digital cameras have the option of capturing black and white images directly in the camera. It can be a nice feature to have sometimes. But you can achive much better results by doing the conversion yourself.
Digital camera sensors do not capture b&w images, they capture color images with three channels, each describing the lumniosity of each of the colors red, green and blue. Consequently, there is always a conversion taking place when you make a b&w photo. The three channels must be made into one grayscale channel. If you let the camera do that for you, you give up all control of how it is done, and how much of each channel is used in the mix.
Making a variable ND filter with circular polarizers

I read about the Singh-Ray Vari-ND variable neutral density filter and found it really interesting. But then I looked at the price tag… over $300 is a little too much to spend on a filter for my taste.
So I started thinking. Isn’t it basically two polarizers screwed together?

The Crop Tool 
in Photoshop is more useful than most people know. At the same time as you crop the image you can rotate it and correct the perspective aswell.
