The wedding pics I received from my photographer in jpg format are only 72dpi. It was taken on a Canon EOS 30D camera. The assistant's photos are 300 dpi though (taken with a different brand camera). I want to print a picture at 16x20, but the photographer said they don't recommend anything over 8x10 (which for a wedding picture seems small). Will the 72dpi make the picture pixelated if I print it larger, and if so is there something that may be able to be done in converting these from RAW to jpg to have them be 300 dpi?

It's not the dpi that matters, but how large the photo is. What are the dimensions (in pixels)? This will determine how large you can go with a print.

Just for your information, the native resolution of most pictures when viewed on a pc is 72dpi.

The pixels are 3504x2336. Another pic I wanted (which is 300 dpi) is 1929x2702.
The other reason I ask about dpi is that I was looking into some flushmount albums who recommended a minimum of 150 dpi for any pictures in the album. But, just as you stated, I've read other things that dpi isn't the primary concern. Do you have any guidelines on pixel size? Thanks!

I hope this helps, this is the pixel level difference, even though the other camera has 300 dpi (I'm assuming a Nikon), and the Canon has 72 dpi. Each camera can have a little play in size. You can up size the Nikon, and you can down size the Canon without a quality degradation.

That dpi number you see is an arbitrary number, merely put in to fill a compulsary field in the Exif information attached to each image. It could have been any number.
What matters is the real dpi which is obtained by dividing the pixel dimensions by the size of a print to be made. The 30D image (2336x3504) yields a 16x24 print at 146 dpi (if you want a 16x20 print, 4 inches will be cropped off the long side - be sure to tell the lab exactly how you want it cropped.) 146 dpi is essentially the same as your 150 minimum.

And just to confuse you further,, your 72 dpi image is 8 megapixel and your 300 dpi one is 5 megapixel.

are these the final photos? Are you sure these are not proofs? I make my proofs 72DPI as well so they cant be reproduced with any kind of quality. If these are final photos you need to go back and request your photos be 300DPI.

Perhaps you should also read https://photography-on-the.net …/showthread.php​?p=3740438 as your understanding seems lacking

I wonder if he has a lot of people deciding not to buy after they receive the proofs.

I purchased the digital "finished" files as part of the contract. I actually had to have them reproduce them as the original file sizes were pretty small (leading me to believe they had been compressed too much in the conversion from RAW) and there were some issues that had to be corrected. I was going to purchase some prints through them but I want something larger than 8x10 and they say they don't order them bigger than that (which just seems odd to me). So.. I think I'll have to live with what I have and do the best that I can. Thanks for alll the info - the post at
https://photography-on-the.net/forum/....php?​p=3740438 is great info!

Limiting a 30D 8mp image to 8x10 is odd. I regularly print A3+ images from (admittedly) uncropped frames and I am very happy with the quality. It comes as a surprise that some professionals seem to misunderstand this stuff. I am a sailing instructor by profession and its like a YMI not understanding the Collision Regulations, or the theory behind why a sailing boat gets drive from the wind.

800x533 pixels @ 72 or 300 ppi will still be 800x533 pixels...
