I took some shots today of my co-worker and his son on their dirtbikes and was wondering the following:
1. What would be the largest print that can be printed without loss of quality?
2. Is there a way to 'batch re-size'? I can 'batch edit', but resizing is a different story.
3. What are the typical sizes available for printing at most 'photo outlets'?
The photos were taken with my 7D @ 3008x2000 @ 72 DPI. Also, I have PSP 8.0.
I remember seeing another thread on this a while back, I just cant find it.

| I usually resize my pictures to 1600x1064 or so, and have printed very nice looking 8x10's from that size. You can either use the image resizer powertoy from Microsoft (I personally don't like it because it doesn't have a 'keep aspect ratio' option), or just set up an action in photoshop and use the batch/image processor. |

I use Irfanview to batch resize all the time...it's extremely easy to use, even for someone as non-technical as me. You can download it for free at //www.irfanview.com and once you have installed it, use the Batch Conversion/Rename function from the "File" dropdown menu. You can set it to do some basic editing all at the same time, if you want.
For most photo outlets, you're looking at 4x6, 5x7, or 8x10 as the typical sizes that most folks might want, though you can't really get those from one crop. You might have to try different crops with the different aspect ratios to see what looks best and then let the co-worker choose what sizes he might want.
I have no idea about what size print you can get from your camera, but my 10D's original files are a little smaller than yours and I've printed 16x20 with no problems at all. You should be OK for at least that size, providing that there is little noise in the original.
Hope this helps! :)

Thx for the info you 2. Theres only 1 or 2 he might want printed in a bigger size. The rest..well, we'll see. I uploaded a few of my favorites, if I could get some feedback, I'd be most grateful.

1-Given your 3:2 aspect ratio I'd say 16 X 24 is the largest reasonable uncropped sized print you could make. That is in basic agreement with Laurie. Anything up to 11 X 14 should be fine without extra effort.
Your photos are taken at 3:2 aspect ratio. That is good for uncropped prints at 4 X 6, 8 X 12, 10 X 15, 16 X 24. You do not have to crop off much for 5 X 7. Other standard print sizes like 8 X 10, 11 X 14 and 16 X 20 will require more significant cropping.
I've made display quality prints at 16 X 20 and accounting for camera aspecting differences between our two cameras your starting pixel density for a print at that size is about the same as mine.
But be advised to get a really good print at larger sizes you need to to pay very close attention to the quality of the image and go over it with a fined toothed comb to remove defects. I review mine at 400% size. And then, by some means, upscale it to the larger size and then go over it again to remove remaining defects that crop up after upscaling. That is a time consuming task. I sometimes spent several hours on just one image to do that, but for good quality it is worth the effort.
Photo processors will accept attrociously small pixel densities for printing, but you really don't want to send anything less than 300dpi for the print size you want.
2-Go with Laurie's suggestion.
3-Most big photo outlets will print up to about 20 X 30 and the other sizes mentioned above. Places like Wal-Mart and Costco do not charge lots but they use thin, cheaper papers.
