First of all, a random title. I am looking for some help with two things. Firstly i have recently purchased a macro lens and there are a few things i am still confused about. Like what are the best settings regarding aperture size etc. Also is the point of a macro lens to get better pictures when your closer to the subject or when your zoomed in from further away cause i have read different view lately. Secondly is anyone here a user of gimp? Can you use tutorials for photo shop to help you with gimp as they are basically the same and also can you direct me to a website with gimp tutorials regarding photo manipulation? Cheers in advance.
