| Hey, guys... I'm new here, and I have a question about using photoshop and retaining proper formatting for developing. I took a couple of pics I shot early on, just after I bought my EOS 300D, and went on down to wal*mart to test out their developing. I had previously edit these photos in Photoshop. Well, a couple of the shots didn't come out, and before I waste any more money making mistakes like that, I was wondering if anyone could give me advice on how to save my images in photoshop, while making sure not to save it in a funky format that the digital lab doesn't work with. My suspicions are that it has to be in RGB, 8 bit color... Please help! |

Not sure if it matters if it is 8 bit or 16. RGB is normally prints and CMYK is normally magazine type stuff. Not sure if it matters if it is RAW or jpg but I usually take jpg.
You should also take note of what size you want printed - 4x6 or 8x10 etc and ideally crop it to that ratio beforehand or else their machine crops off bits. Ideally you want it above 150 dpi for the size you want printed. If you shoot black and white or duotone then sometimes you will see a slight cast to the image from their printing.

For almost all of these photo printers you ideally want your file at 300 dpi at final print size (150 minimum) in 8-bit RGB in JPEG ("Baseline") mode; a very few places will feed their printers TIFF files. Most of these also enlarge the image by 1-2%, so if you have critical parts of the image near the edge, you need to make an allowance for that; here's a couple of postings from this recent thread which have more info and links.

As far as I know, that is just how the Fuji Frontier (which DPCPrints uses) works. From this link, which has some info about these types of printers:
Most labs have their printers set up to increase the size of each image by 1-2%. This expands the image beyond the borders of the paper. The reason is to prevent a white strip from being printed along one or more edges if the paper is not perfectly aligned within the feed path.
...
Cropping can be minimized by adding a thin border around the edges of each image (increasing the canvas size). When printed, the borders are cropped off, preserving more of your original images.
At the very bottom of the above link is a table that shows how big to expand your canvas before uploading the printable file. Notice that you are expanding the canvas, and not resizing the image. So if you have a 300dpi 8x10 (which would ideally be 2400x3000 pixels), expand the canvas (without resizing!) to 2434 x 3036 and you should get very close to your desired print, since the extra canvas space is the part that will now get "scaled away" by the Frontier. |

Thanks again!!! |
Ditto, and thanks to the folks at Dry Creek for putting that together! Note they also have that document available as a downloadable PDF -- I'm going to print out a copy for the tech over at Costco where I had this exact problem a couple of weeks ago. |

| I also save the "final edited image" in Photoshop or TIFF or some other uncompressed format, and then a copy of that as a JPEG for printing. |

I created my prints using TIFF files, only because I know a local digital printer accepts them using automated ATM-type photo print services. The results are great, but I was a little miffed (as most DSLR owners are) that you lose the left and right edges of your shot.

Ah, very helpful, everyone. I appreciate the blazing fast replies, guys! GeneralE, your advice was spot on! I suspected that I may have saved one or more of the pics in question in a progressive jpg format, and that could have been the problem. Sounds like you hit the nail on the head!
I will be spending a lot of time on these forums! Thanks again!!! |

You're welcome ... that is our "job" :)
I don't really know about any of the profiling stuff in that document (EddyG or Gordon would know more), but you can search from the main forums page under "profil" and find lots of threads on the subject.
The sizing information for prints is at the bottom of the web page or on the last couple of pages of the PDF> |
