72dpi wedding prints - quality issues

<p>Hi Everyone<br>

I'm not a professional wedding photographer so I hope you guys dont mind me asking your advice.<br>

I am shooting my friends wedding next month (I've only ever shot 2 before) on my canon 400d. I understand that the canon takes photos in 72dpi, however, I always understood that for optimum print quality photos should be in 300dpi? Is this correct? <br>

Therefore if I shoot this wedding at 72dpi do I need to go into photoshop and change the image resolution to 300dpi in order to get good prints.? Does it really make a differnce or am I going about it the wrong way. What do the Canon users do?<br>

I'd appreciate any help you could offer<br>

Thanks<br>

<p>This gets asked all the time so I won't go into detail (google youre question here). Ignore the 72dpi - all that matters in the total pixel count and your camer is fine. And your prints will be fine.</p>

<p>"do I need to go into photoshop and change the image resolution to 300dpi" - No. DON'T' change the resolution, just the print dimensions to what you need. You'll see the dpi go up.</p>

<p>It doesn't need to be said again, but it does since so many people make this mistake, so I will just say "listen to Sheldon." "DPI" is a header instruction to a printer, not a characteristic of a digital photo file.</p>

<p>Your camera files are in ppi-pixels per inch. Printers use dpi-dots per inch. The two terms are not interchangeable though many people do use them that way. The only thing that matters is the number of pixels in your file. If you sensor is 3000 by 2000 you have a six megapixel image. If you print at 100 dpi it wil be 30 by 20 inches. If you print at 200 dpi it will be 15 by 10 inches.</p>

<p>Thanks for the advice everyone!</p>

<p>If you really want a clear understanding of dpi and resolution. There's a great and enlightening explanation on both at...i believe it's....light landscape or luminous landscape. Not sure on the name...been a while...maybe someone knows the site I'm talking about, but they really give you a complete understanding of resolution....and there's so much more then just dpi.</p>

<p>33.3 x 50 @ 72 dpi is the same as 8x12 @ 300 dpi. Both are approximately 24.7 Mb. This is the more important number. <br>

I work in a digital lab and the first thing we look at prior to printing is the file size. If that file opens up at 5x7 @ 72 dpi, I would tell the customer that it's too small. Can we print it? Yes. Is it going to look good? No. <br>

Here's a tip: on most of the smaller digital photographic printing systems: Fuji, Noritsu, etc., the file needs to be 300 dpi at print size. (4x6 up to 10x15) For the larger outputs: 11x14 up to 48x120 and larger, you need at least 200 dpi at print size. </p>

<p>One more time, camera files are in pixels, not inches, so it doesn't matter whether you call it ppi or dpi, it's irrelevant until you establish a print size. Camera files are in "nothing per inch."</p>
