| Youre the expert, Ill give it a go.
When testing new papers, maybe a series of prints 20 to a page (5*4)
First one in the row -20 units next one -10 then normal then +10 then +20
It could be any of the RGB colours, maybe a different colour along each row
Or it could sharpening, adjusting one of the variables only in each row, eg keeping radius the same but altering blur
Or it could be brightness
Or contrast or white balance
I would look on it as a learning tool, used less the more experienced I become, until I come across a problem image then use it again to find the best solution.
_ A bit of background when I did analogue photography I obtained a Licentiateship to The Royal Photographic Society of GB. However now I am digital, although my photographic skills are Ok, my darkroom (pixel) technique is awful. |
