I came across some foggy landscapes that I shot in last autumn and now took the opportunity to process.
Texturizing soft foggy landscapes is a lesson in texture control. It quickly happens that one overpowers the picture by using powerful blending modes or very grungy & strong textures. So besides the reluctance with PS's adjusters one has to carefully choose the texture.
I found out that it works quite well with textures, that have a fine structure & don't have too much colour. So, you might have to alter the textures colour or reduce it to your liking.
Soft creamy tones are perfect.
What helps keeping the light mood & the atmosphere is using one texture layer in blending mode "normal". This will most likely be the texture that will be setting the tone & structure of your image. Additional texture layers will modify & tone your picture.
I only used textures from my Soft-Grunge-Texture-Bag . They also work quite fine with vintage processing/ monochrome pictures, as you can see in the following pictures.
These where processed in a similar fashion, except that I found them better in only one color.
Thanks for your attention!
