ok, i really need some help here. up till now, i always ordered my prints through Smugmug (normally smaller sizes with the largest being 24x36) and i have always been super happy. however, i just got an email from someone that wants to buy one of my images but he thinks that 16x24 is too small. i am guessing he wants serious poster size but the problem is that smugmug won't let me print that size for this particular image. the main problem is that i do not have any idea on how to get an image ready for printing as far as upsizing and all that stuff. what i need from one of you expert is a crash course in how to do that so i can be ready to sell such prints if there is a demand. idealy what i would like to do is send the file that i would like to print to one of you and have you upsize it for me and explain to me exactly what you did. i am having a real hard time understanding the whole printing issue so any help would be greatly appreciated..
