Just got back an 8x12 enlargement from a slide. The print looks like it was lightened somewhere in the process and also the colors aren't as rich as the original slide. I'm aware how prints from film are "adjusted" when developed, however I'm curious if that occurs when enlarging from slide? Or is it that an image gets "lighter" when enlarged. I am new to enlargements (small, small budget) so forgive the n00bness of the question!
