Studio photography more often than not rhymes with flash photography. Product and still life photographers can sometimes have tens of lights set up for a particular shoot. Keeping all of them at the same colour temperature can be a challenge, and it most certainly is if you mix different models, different brands and different types of lights. That’s when a kit of colour correction filters comes in handy.

Those square of translucent plastic sheets are meant to be put on top of you flash head or at the end of a modifier. They can warm up the light (using a CTO filter) or cool it down (with a CTB filter). I found that the colour temperature of small speedlites is cooler than that of bigger and proper studio strobes. Putting a ¼ CTO filter on the speedlite’s head will warm it up so that it gets to the same level as the strobes. Some kits come with several square sheets of different colours. What I did with mine is that I stuck a thin Velcro strip at the top and bottom of a properly sized sheet. I then wrap the flash head with the complementary end of the Velcro. That way, I can easily stick filters on top of the flash. These filters can also be used to stylize a shot by placing, for example, a red, green, or even magenta squares in front of your strobes. The resulting effect can sometimes add interest to an otherwise boring image. This Rosco kit is perfect because it contains lots of material with which you can easily work.

These colour correction filters are one tool that I definitely recommend every studio photographer to have. Correcting for the different colour temperature of different light sources is not something some enjoyable to do in post and can literally take a few seconds to do in-camera.
