Hello,Hi David. One way to push it in your favour maybe to process the files in ACR using it's upsizing option and output at that size which at it's largest will give A3+ 50mb @ 8bit 300ppi. At least they appear to have more to play with. I keep seeing the opinion that upsizing in ACR is preferable to Photoshops own upsizing. My understanding of the billboard size required is the same as yours - the resolution needed is less because the viewing distance to the back of a bus etc is greater than an A4 print...unless your a pizza delivery biker!:-)
I'm in the middle of negotiating for a job...
I've sent over examples of files that I've shot on similar jobs using a
Nikon D100. The camera produces files with a resolution of 3,000 x
2,000pixels (17MB Tiffs - 8 bit).
The client is happy with the aesthetics, but has expressed a concern that
the resolution will not be big enough to cover all future (not yet
anticipated) uses. He gave as an example 'back of a bus' or 48 sheet poster.
(The job I'm being commissioned for is a web site and A4 brochure use !). I
feel the technical guy at the agency is playing 'devils advocate' with me -
but I don't blame him for that in the slightest. Nothing like 'covering all
the bases', eh ?
My question is - What's the list opinion on this ? Will 3,000 x 2,000 Nikon
D100 pixels do the job ? I can't ask any printer the question, as the
question I have been asked by the client is theoretical, and there is no
printer in the frame.
I was under the impression that RIPs made a good job of interpolating up for
poster production, and that anyway the dpi was very small on this kind of
production, which I would surmise will work in my favour. Am I correct ?
Regards. Patrick.
