I'm going to ask most of you to take a trip into the past...since I'm still sort of there. I'm currently shooting a Canon 1Ds (the old 4.2 Mp) version. Got it used through a buddy at Sports Illustrated and absolutely love the camera. The 8.2 and 16.2 Mp upgrades get me all aroused, by I'm a simple guy and can't justify handing over $7,000 for a new body. Not yet anyway.

So I'm currently looking at dropping a little bit of money on a nice Brewer Cantelmo portfolio, and have gone back and forth on size. I had settled on a 9" x 12" format, but in reviewing some old posts was seeing the value in going right to 11" x 14". Only one problem...

Will a 4.2 megapixel camera give you the type of quality that you need at that size? When I edit images I am doing so at image sizes larger than that and they appear to be plenty clear and crisp. My buddy (who sold me the camera) tells me that he's had work off that camera go to 30" x 40" with no noticeable loss in quality. But he's also a sports guy, albeit an outstanding one, and his view of the world is not the same as the collective G1 braintrust.

Your thoughts? Would you stick with the smaller portfolio size now, and look to upgrade when I finally improve the camera, or am I worrying about nothing? As always, I thank you!

Wow, I know that it's practically an archaic camera by most pros' standards, but no one has an opinion?

You will have no problem printing to that size. You can beef up file sizes through numourous methods if you feel the need, I doubt you will need it.

Good luck,

You could pull it off, but your cropping options will be very limited. Also, you wouldn't have to plop down $7,000. The new Rebel XT's are going for about $650, with the same sensor & brain as the 20D, and you could probably find a used one for under $500.

What you actually have, if indeed it's a 4.2mp image, is a 1D (no "S") Mark 1. Owned one for about a year, used it with a Sigma 70-200 2.8 EX lens. Outstanding camera.


To your question...the increased sensor size combined with the larger pixel pitch makes that camera perform better than most 6mp cams. Enlargement CAN be an issue, but at much larger sizes than concern your book. I've seen gorgeous 11x14 double truck images (that's 14x22 btw) produced from both the Canon D30 (the old one, before the 10D) and the Fuji S1 Pro. And both of those cams were 3mp native res.


It's an easy, cheap test. Take one of your best shots from the 1D and crop (actually, a select - copy - paste into new image) a 620x930 section from the 2464x1648 original, save it to disk and have it printed at your local photo lab as a 4x6" print. That'll give you the same ppi count (154) as a 9.5x14 from the original, and therefore the same visual quality. Hold at arm's length and evaluate for sharpness and noise grain. Bear in mind that 11x14 will require cropping from the long end of the image in some manner as that camera is 3:2, and produces an 11x16 proportion. The 1D images tolerate a rather large degree of both up-res and sharpening without image degradation, especially if shot in RAW.


For the double truck, if you choose to do that instead of having them rotate the book, I'd suggest an up-res to 4000 on the long side, and then draw a selection to 2002 wide for both left and right sides, and print each as 11x14.


Bottom line, you get the shot, she'll print up just fine.

I agree with the above.

Also that camera still produces some excellent pics and dont worry about the 4.2 mp. It has good a good sensor. I wont even trade it for a 20D!!

I had some of my rally car pics blown to A1 size in good quality for top advertising companies that is full of crap normally. Must add to it thatr for A1 I used Genuine Fractuals to boost it.

But for your size it is no problem
