Resizing Files I read somewhere that it is possible to enlarge files without losing quality. Many stock agencies don't accept files less than 55mb. When I convert my raw file to TIFF format in 16bit mode I get a 36mb file. Is there a way to satisfy the 55mb requirement of stock agencies?

What is the size of your TIFF image? Is the size the stock agencies are requiring a particular? A raw image of 16mb will produce a final image 8 x 10 at 720dpi of 79.1MB. Hope this is of help.

Stock agencies set that as a criterion in order to weed out everyone who buys a digital camera and wants to be a stock photographer. One can only imagine the millions upon millions of files they would get if anyone could send their files to a stock agency with no type of limitation. Of course, 35meg is enough for stock usage, but the 55meg requirement implicitly says that one needs to spend the money for a 1DS or the new Nikon in order to submit material, and that will automatically knock out any amateurs who do not want to invest that kind of money in a digital camera. I'm a professional and still primarily shoot film for that reason. A transparency scan is 54meg in the mount and about 60 meg when scanned outside of the mount using a desktop scanner in 8 bit mode. But, stock agencies have you there, also. They'll require any scans being submitted to be DRUM scans, which at about $25 a scan will pretty much cut out the amateurs from flooding their mailboxes with CDs. Unfortunately, if you want to be a stock photographer these days, you'll need to spend the $5000+ for the Canon 1DS, the Nikon 2X, or the new Kodak DCS. Or, get into the stock agency the old-fashioned way ... by submitting about 500 top-quality transparencies for review.

Thanks, Doug and Tony, I most appreciate your prompt responses. I shoot with a Canon 10D, raw files are 5-6mb. Judging by Tony's response, I have no chance with this camera. I wonder: Will they be able to tell a quality interpolated file from a TIFF directly converted from raw?

If your camera is 6mp or above and you shoot RAW and convert to TIFF, then you should be able to upsize the photos using Genuine Fractiles and be able to make the "grade" ... hth

Leonid, I shoot with an Olympus E-1, which has a 5 megapixel resolution. I almost always shoot in SHQ Jpeg mode and convert to TIFF for saving print files. My camera produces a 6X8 in. image file at 314dpi. I frequently resample those files to 12X16in @300dpi which produces a 54 MB TIFF file for printing. I use Photoshop Elements 2 for resampling using bicubic resampling. The prints produced by those files are incredibly clean and sharp - as good as anything I've ever printed from 35mm film. So you should have no problem resampling your 10D images to 55 MB with excellent results. I firmly believe that the case for huge megapixel cameras is grossly overstated in most instances. Your Canon is totally capable of producing sellable stock images - as long as the images you capture are good quality.

Unfortunately, Leonid, the stock agencies make the rules, and they want at least 50 MB raw files without interpolation. I agree with you that large MB cameras are overrated, as I use a Fuji S2 and those files are not acceptable. Hence, I shoot film and let the stock agencies do the digitizing to their standards.

Thank you, Greg and Tony, The only thing I don't understand, Tony, 50mb RAW. Did you mean NOT INTERPOLATED? For all I know, even medium format digital cameras don't produce such huge raws. Thanks again, and I wish both of you to be happy and successful.

The only camera on the market that can give that size file is the Canon 1DS. But the new professional Nikon digital, at about 12 megapixel, will also be in the 50MB range.

It's pretty basic. When you start a business, you get the pro tools that will deliver quality service or product to your client. What kind of tools do you want your doctor to use on you? Your accountant, dentist, architect, contractor? So, do you have an interest in doing more than your competitor, or do you just want to barely make it to the edge? Do you want to spend your time on the computer, or out creating hundreds of perfect, computer free, images behind your camera?

First of all, I would like to express my gratitude to everyone who took part in the discussion - it has been such a lively exchange. Just out of curiosity: I understand that 55mb requirement is the first line of defence of stock agencies. How do they defend themselves from tons of transparences, produced by point-and-shoot film cameras? Their owners may entertain the same ambitions as the owners of digital point-and-shoot cameras.

All major stock agencies request an initial submission of 200 - 500 images. They check for quality, consistency, talent, unique point of view. It's unusual that anyone except a professional or professional-quality amateur would have 200 top-level images, consistently producing professional work on a monthly basis.

Good to the point, Tony Sweet. Whatever professional field one pursues ... or let's say it this way, when one steps up to be a performing professional there are no short-cuts. You are the cut above all others. You no longer have the "easy" 40-hour work weeks. You can no longer tend your garden or care for any pets. Your point-n-shoot SLR gear goes out on the next garage sale. My client is my paycheck, I pursue to deliver better than what he requires.
