I've been put in charge of putting together a promo poster for a network which culls together gallery photography from various sitcoms. The photos are of varying degree of quality and age, I would like it to look as if it was all shot in the same studio. Was wondering if anyone had any tips or could point to some resources for matching all these photos I have and making them look consistent without overly stylizing them. I'm having a tough time with light sources, grain, and colour in particular.
I know this post is over a week old now but I do have a tip for you to match grain using a couple of effects through PS, this technique will work in both CMYK and RGB modes.
Follow the steps below:
1. Begin by creating a new Layer
2. From the colour picker define a colour C=50, M=50, Y=50, K=50 or if using RGB R = 127, G = 127, B = 127.
3. Now fill the new layer with this colour.
4. Select "Add noise" from the "Noise" Section under filters and apply an amount of 5% (this is just a value for demonstraion, any subtle amount will do, this just works for me usually).
6. Now change the "Layer Blending Mode" of this Layer to "Overlay".
7. You should now see that the original image (underneath this layer) has a fine grain running through it. To alter the appearance of this grain (if you wish) I suggest transforming the layer you just created or by altering its opacity.
