Photography Question

Can I enlarge to 16X20 w/ a Rebel XT


Hi, I shoot family portraits w/ a Cannon Rebel XT. I would like to print some 16X20's. Do I have to do some resizing in photoshop to get good quality prints or use some sort of software? Or can I just send them off to the lab and get good quality? Thank, Susan Robertson

  You're probably pushing it a bit, according to a chart I found in George Schaub's new book on Digital B& Printing. His chart says:

Print Size File Size Camera MP Count
16X20 72 MB 24 MP
11X14 42 MB 14 and up
8X10 18 MB 6 MP
5X7 12 MB 4 MP

The XT has an 8 MP chip, so you'll need to enlarge your file carefully. This shouldn't be done in one swell-foop, rather in incrememnts - til you get the largst file size you feel comfortable with. It'll cost you, but experiment as you go.

Note - even the biggest Canon SLR woill only give about 12 or is it 16 MB. So it something well worth trying. And, you'll probably be successful.

You might try a smaller print mounted on 16X20 matboard. Remember, that's a big print.

  Yes. You can. You can make absolutely stunning 20x30's or larger with 8MP.

Send the full file to the lab. Oversharpen a little. Let them res it up. It will be perfect.

  Again, leave it alone and let the lab res it up. They can do it better. Just get the image the way you want it, over sharpen, and hand them the full res image.

  Keep in mind that when you print pictures to place on your wall you have a viewing distance of at least a few feet. That means you can get away with a little bit because no one will be able to see the tiny details that may be lost. I read about this in a view threads here at better photo so I tried it out and printed my family portait as a 16x20. I shoot a Canon Rebel 300D (6.3 megapixel) and it came out beautifully. I used bicubic smoother in Photoshop as Howie suggests and it looks perfect.

My only problem with the whole experience is that I took the file to a lab I had never been to before and they tried to color correct it using brightness/contrast adjustments in PS. The lady acted like she knew what she was doing and like she was superior to me but the truth is that she didn't really know much at all. If she doesn't know how to color correct then maybe she wouldn't have known how to resize properly. I'm just pointing out that if you don't trust your lab 100 percent then you should resize it yourself.

  Again, a professional lab can resize better than anyone can do it on their PC. Let the lab do it, unless, it's not a pro lab. Then, do it yourself.

  Thanks everybody! I can't wait to try this. I just started using mpix.com as my lab. Does anyone have a great lab they recommend? Thanks, Susan
