72 PPI HELP?!

[KmH]

Canon cameras by default set the ppi to 72.
Which is why I asked if you use Canon cameras.

Can I change this?

I don't think so, but I'm a Nikon shooter.
Check the User Manual for your camera.

The property of image in your computer is a resolution (like 6000x4000 pixels).
The PPI (pixels per inch) is not relevant until you actually print the picture - it is the resolution divided by physical size of the picture. And it tells you the picture's puxel density.

Ok, so this obviously matters if my clients will be printing the photos.

No in fact it doesn't matter.

That's the same image at two different PPI values. The PPI value has no effect on the actual image pixel dimensions. It is simply recalculated when you change the print size.

They need to be at 300PPI and no matter what I do, I can't export the photo at 300 PPI... its like PS is changing it!?

The PPI will change at time of printing when the print size is specified. PPI is pixels per inch. Change the number of inches in the print and the number of pixels per inch has to change if you have a fixed number of pixels.

Thanks, great info. I didn´ know about the box and always copied the pixel dimensions width, changed the ppi and then pasted the width back in again to keep the pixel count the same. You never stop learning.

In regard to dpi in general, even graphic designers and some printers don´t know what it really means. I do some graphic works for a client from time to time and his printers always ask me for 300dpi. I then say 300dpi AND...??? They don´ know the answer, but they need to tell you the final print size along with the desired dpi. Otherwise it is similar as if you´d go to the grocery and ask for 300 Salami instead of 300 grams Salami.
I even created a page on my website where I show them the difference - it is in german though, so not worth posting here - but this is an image from the page: both images are 300dpi - you see, it doesn´ tell you anything without knowing the size:

To be on the safe side, always send the full resolution to the printers.

No, both images are 300 PPI not DPI. "P" is for pixel and "D" is for dot. You only have a dot when you have ink on paper. Printers print dots and photos are made up of pixels.

Here's another way to display the point that PPI has no meaning without the size specified. "I" is for inch.

"To be on the safe side, always send the full resolution to the printers." Absolutely! Both of those photos I just posted have a resolution of 212 X 328 pixels.

I had a similar problem with my local lab who insisted they scanned negatives to give a print at 300 ppi. They still think they do but they no longer mention it to me.
