I was the Cinematographer (Director of Photography) of the "This is Jazz" video clip. One thought on the general visual feeling/filter was the cross processing.

Cross processing (sometimes abbreviated to Xpro) is the procedure of deliberately processing photographic film in a chemical solution intended for a different type of film. The effect was discovered independently by many different photographers often by mistake in the days of C-22 and E-4.

But we are on the digital era. How to achieve a cross processing effect in Photoshop?

sample photo

photoshop Curves have already a preset but I don't like the result. I assume that you know "how to" and "what is" Curves.

so we start our manual way

add a fill color layer (Menu Layer > New Fill Layer > Solid Color). I chose a green color. You can experiment. Opacity to 8% - 10%.

add a Curves adjustment layer

add contrast to Red and Green channel

the opposite to Blue channel

switch to RGB and click the "hand" at the left top corner. Add contrast or lighten your photo with the eyedropper. You can make that by tweaking the RGB line.

this is the final photo Curves

and our Cross Processing Effect

If you understand nothing of the above, you can still buy the Nik Color Efex
