I've supplied a client with digital files 9.67M in size for editorial PR use in magazines etc. The client wants to use the pics for A3 size posters. I understand there is a formula that exists that takes into consideration size of print, dpi etc that you can use to get the file size you need. Is this correct and does anyone know what that formula is and how it works?
Dear Bob, >From 9 mb files um, What camera was it shot on ????. If the jpegs were saved at level 12 maximum quality then there should be no disernable quality loss, if they were going to a1 then yes go back to raw. You could just upsize them using bicubic smoother in say 15% steps 4 times and that will get you a 30mb. However I rekon at a3, you arn't going to see the difference. I think it woul dbe important in this instance to resize the image in photoshop keeping the files the same, then save as tiff for the repro guys. I find sometimes, that leaving the small fle sizes the rips do a bad job, where as if you resize in p shop even though its seeing pixel dimensions it seems to do a better job. May be talking rubbish of course. Don't know the technical ins and outs on rips and how they see files. It would be good to know what the original was shot on. cheers Ian Reynolds =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
