I have traditionally processed my images using the default black background in Lightroom or Capture 1.
I initially responded to the strong and clean look of the black surround and even use a black base for this site.
Contrasting any image against black can do that. It can make colour pop and increase depth, sometimes even intimacy, but the result can tend to be quite darkly editied images, especially when used by others in other circumstances.
I decided to switch to a ehite editing background recently and it had an immediate effect.
My images look more defined on the page, helping with cropping and composition checks (they look much like an image on a book page), and my perception of image brilliance and density has also improved. I am happier to take an image to near white, making them look “happier“, which makes sense for images of school children.
An example of an image that just jumps out on white.
It also helps with pre-visualising for printing.
Another odd thing, probably not related, is that I often miss typos when writing my blog posts on white, but spot them the second I see them on the black publish page. Probably more Freudian than that.
