Lately, I've been blogging about how my new camera shoots images with 300 ppi (pixels per inch, a.k.a. dots per inch). However, the truth is that I almost missed this fact.

When I was regularly taking photos with my point-and-shoot, I took it for granted that each image had 72 ppi. This was in part due to my former post-production process; I'd process all of the photos from a shoot via the "Process Multiple Files" option in Photoshop Elements (i.e. resize, sharpen, convert to JPEG max quality). If I was only processing one photo, I'd do these steps individually.

The other day when I took "practice" shots with my DSLR, I was messing around with them in Elements.* I think I was about to resize them when I noticed the extra ppi I gained just by using a different camera.

I was elated, but this boost would have been worth nothing if I didn't stumble upon one fact - when I was processing multiple files, the ppi was set to 72. Ergo, when processing my DSLR's photos, I'd have to set it to 300 to prevent any loss of pixels. Of course, point-and-shoot processing won't change; I'll just need to be extra cognizant about the ppi setting.

*I shortened "Photoshop Elements" to "Elements" so I wouldn't have to keep writing the first term over and over again.
