Question about enlarging photo's (Page 2): As above go to another outfit and insist that they be printed. My guess is that you will not have a problem having them printed. That idiot...

I tried to get them printed at Costco, and it would not accept them when I tried to select them the lady told me it would not print them because they were not good enough quality and would come out grainy. I did enlarge some before from my Rebel t2i with no problem, so I was surprised. I do need to check my settings I have not done that yet. Still learning Thanks for all your help.

As above go to another outfit and insist that they be printed. My guess is that you will not have a problem having them printed. That idiot at Costco shouldd not have refused your request. You might not like the result but you are the customer, insist. Might not be a bad Idea to go back to costco and complain to management about the discourteous service.

The first thing I do is run my RAW shot through Photoshop for size and make them 11x7+ or so, with 300 pixels not "72". Then work with lightening or darkening, then sharpness. (but not too much.) I then print an 8x10 on my printer and if the smallest part looks good enough to blow up I'll send it to Costco. The largest blow up would be 16x20 for an 18 mpxl camera, like the T3i. If I get a "warning" from Costco about grain I go smaller till the warning doesn't come up.

I put a few photo's on a flash drive I took with my new canon 6d using a sigma 150/500 lens to be printed, I used picasa to change them a little and cropped them. I wanted 8"x10" prints and it would not print them because they told me they would come out grainy the photos were not good enough.
My question was it because I did not shoot them in raw, or did I crop them to much ? I am just learning a little bit about getting off of auto I was using manual setting.

Your resolution is too low for cropping and enlarging! You need at least 360 (vs 72) and if you shoot raw, you will get even higher resolution.

In the early days of digital development, Kodak determined that the minimum level of detail to print is about 240 to 250 pixels per inch of SOURCE MATERIAL (scanned or photographed) reproduced at 8x10 or 8x12.

So, an 8x10 requires about 2000 x 2500 original, captured-in-camera pixels for photographic quality reproduction, defined as the level of detail that makes the pixels invisible to the unaided eye at a viewing distance of the diagonal of the print (about 13 inches or so). This is equivalent to a 5MP image.

Amateur labs may let you fudge this a little, but they generally know that you will BLAME THEM if your prints look crappy, so they have software or guidelines to reject your files if you want prints at larger than the file dimensions you send.

Once you enlarge beyond about 8x10 or 8x12, the need for resolution diminishes somewhat. The same file that makes a great 8x10 will probably make a great 16x20, IF the subject matter will be viewed from the 26 inch diagonal of the 16x20 print. If it's a landscape or a group of people, no You'll need the full 250 pixels per inch of original, in-camera detail for that sort of subject matter.

Remember, when you crop, you are throwing away a lot of the detail in the original file. Then you are enlarging the remaining pixels. If you enlarge so there is less than 240 pixels of original file detail per printed inch, on an 8x10 or smaller, the results will be less than optimal. By 120 to 125 ppi, they'll stink.

Maybe you shrunk the files when you exported them. Check the settings on your export. Also, if at the long end of that lens it takes real good technique and likely a tripod to avoid camera movement blur.

Did you mean 11"x 7" or 11" X 17"? If he resizes the file to 7", he'll have a tough time getting a 'good' 8" print?

the last picture you posted (bird on a branch in the middle of the frame) has a lot of jpg artifacts..so please post original.

next time tell them you want grainy pics for artistic effect lol

What comes out of my camera is an image that is, for example, 59" wide x 35" high x 72 ppi. When I resize in Photoshop to what I can actually print as soon as I make it 11" wide height will be 7.3. I then decide how big the ppi will be. the size is built in unless I uncheck "Constrain Proportions".

see if you can change the resolution to 350 that might help

Thank you for your help, I don't use photoshop right now only picasa and my canon program. Once I learn more about getting the right settings on my camera I will get into post processing just started reading, Understanding Exposure.

If you sent these to the printer at 72 dpi that is ONE reason why they rejected them. Save for print at 300 dpi.

For a quality print do not use a resolution of 72. Change that to a resolution of 250 or higher.

Also remember that each time you save a jpeg file, it will lose more quality.

At places like Costco, try saving it as an SRGB file.

Hi shoot in RAW. post edit the raw in Light Room. Save the original Raw's, then crop and export @ 300 resolution as a JPEG to another folder that you will send to Costco. From seeing your shot, I would try to get closer to the subject and fill the frame with the bird. Always save the original Raw shot as a raw or Tiff file. Good luck.

You might try on-one's "Perfect Resize" to salvage your existing photos. In the future, shoot RAW only, and save the originals of your best shots before PP.
