Is it okay to enter older images if they haven't been submitted previously or should the image be from 2015?
Is there a suitable category for images of fungi, lichen and such (I'm thinking Plant Macros (Closeups))?
Also I wonder what is considered significant digital alteration:
Are focus stacked images okay?
The digital version of dodge and burn?
Various HDR techniques as in taking different exposures and combining them by hand or software to capture the full dynamic range of the scene?
Small localized color changes/corrections as in for instance compensating for different color temperatures of foreground(subject) and background such as what can happen when for instance shooting with flash.
