Also bear in mind costs if you want to frame your print. Frames off the shelf conform to the standard sizes 8"x6", 10"x8", 12"x10". Of course if this print is a one off then you won't mind paying the extra for framing it yourself or getting someone to frame it for you.
I, rarely shoot to the standard, I crop 90+% of the time, but I do produce some wallpapers which have to conform to screen sizes.
Every picture you take is a recorded moment of your life, it is unique, it is seen through your eyes and your eyes alone, it is composed with your mind, heart and soul and is worth sharing.
