I am going to create some hand painted HDRI's to use in my 3D scene to light my models.
I am going to use Photoshop in 32bit to paint and save out as EXR.
Before I begin, I am looking for the best workflow to do this.
The photographic HDRI's I have all range from brightness value of 0.00-15.00.
So I am looking to paint within these values.
THE QUESTION: Is it possible to make selections based on a range of pixel brightness values?
Is the best workflow for this, to start bottom layers dark and each layer progressivly get brighter as I get closer to light source?
Sorry if this is confusing, I looked around and I dont see many people doing this.
