Resolution question

[Ockie]

Sorry to bring up a question that has probably been asked before, but I can't seem to find it, and yes, I did read the printing and enlargement FAQ, but I'm still not sure, so here goes:

I passed on to the second "round" of some online photo contest and now they need a high-resolution file for printing (they want to print it at around 100cm / 1,389 inches(?) on the long side), they told me they'd need a fitting resolution on 300dpi for that.

I have shot the photo I'm talking about in RAW mode (on a 400D/XTi), and still have the RAW file, which is the one I'm sending as it has no edits besides those that could be done in the converter.

Now, how should I send the file so that it would be in optimal size & quality for printing in the size they told me?

You can open the image and go to image/resize and then change resolution to 300ppi. I doubt they want the raw file though. They probably want a tiff or jpeg.

They indeed want a JPEG / TIFF file... since they want it on a CD I'll just send both...
Thanks for the fast reply eddarr

Sounds like a great way for them to get your image for free. I bet they assume copyright or the right to sell it? They really don't need 40"/100cm @ 300ppi unless they're printing massive enlargements for the judges or selling it to a stock photo site.

A tiff has more info than a JPG and 100CMs is 39.4 inches. The best way to bump up the image and keep great IQ is to use a program like Genuine Fractals. If you just bump it up in photoshop it will degrade the final image.

I thought of that, but it seems like a quite decent contest... organized by a pretty big bank over here, so I'm going to risk it...
besides, I wonder if this image (http://ockie.deviantart.com/art/Contrast-56122927) is interesting for stock sites :)


They do indeed claim copyright for, quoting here, "uso, difusión, distribución, exhibición, comunicación pública, divulgación y reproducción de las obras" which would be (more less and resumed) the right to use, exchange, and show in public, nothing about the rights to sell :)

Oops my typo re sizes. Also I don't personally bother with GF, I just use photoshop and i'm happy with the results. I had a photo of myself taken with a 5D and printed life size, upsized in PS, it looks pretty good.

Good point, they'd need a model release to sell it anyway.

Hmm,

39.37*26.25in*300ppi = 93*10^6 bytes (ie, 88 or 93 megabytes, depending on how you measure them).

Why on earth would they need a file that size? AFAIK no-one who knows anything about digital printing would require an image that size to be printed at 300ppi.

200ppi would be closer to normal for a print that size, and even that would come to 41.33*10^6 bytes (ie, 39.4 or 41.33 megabytes, depending on how you measure them).

Methinks they need a reality check.
