I am slowly bringing to life an old & sturdy Durst 606 developper. It came with a recessed lensboard but I have seen flat lensboards that fit that same enlarger head.
Can someone please tell me what difference in results should I expect when using a recessed versus flat lensboard? And if I use the recessed one (the one I already have) can I use it with any lens as long as the thread mount is compatible?
I must add that I've never used an enlarger before, I apologize if the question is too basic...
Thank you in advance
