I like photography. I usually share my precious photographs on social media websites like Facebook or instagram. I am interested in making a big real poster for the wall. Would anyone help me to find it out how this is possible?
Well, if you are not technically sound then you can use any web based apps available.
Rasterbator is great, but it's not exactly for your ordinary poster, is it...
maybe you need printer tiling function
Epson Stylus Color 660
RonyaSoft Poster Printer
Using Tiling in InDesign CD5
Print posters and banners
Technically, it's quite simple - you need a wide-format printer. Many graphics shops will have them, as will specialist poster printers and sign-printing shops (although the latter may not offer the quality you're after). Have a look in your town for such shops and check with them, or seach for such service online (for example, I've just googled "large photo print" and found a few in my country).
