72ppi digital camera image redux

Sorry for posting this again, but the responses to others with this problem didn’t really answer my question.

I have several 5.0 megapixel images and when I open them in Photoshop, they default to 72ppi and something like 36" x 27". To change them to a higher ppi (and thus a smaller document size) I change the resolution while keeping the "resample" box unchecked. So far, I think I’m doing everything correctly – my images become smaller in size.

What I’ve noticed is that when I open these same digital camera images in a different editing program (my computer tends to default to opening them in Microsoft Photo Editor – blech) they come in as 300 ppi and around 6.5" x 8.5" – which is what I really wanted in the first place.

So the question I really have is: is there a way to change the default on Photoshop so the images don’t automatically have that 72ppi/monster document size?

Thanks in advance

Amy

Sid,

I could be wrong, but I don’t believe there’s a way to do what you want…and I don’t think you should want to, (just my opinion). Apparently, this is never(?) the case in your workflow, but if you could change PS to open everything at 300ppi, then a 1" x 1" @72ppi image would open to .24" x .24" @300ppi.

Isn’t it much better that you can rely on Photoshop to always be truthful about how an image was last saved? Microsoft apps are full of consumer-oriented "automation" features that pros would rather not have as they ultimately compromise true control.

The fact that your, (JPEG, I assume), images open in MS Photo Editor by default is simply a file association issue that can be easily changed.

Sorry if my response isn’t entirely helpful.

Remove MS Photo Editor from your system.

That would be a good start.

Whether or not EXIF data is there and being read by an application has something to do with this I think… do older digital cameras even write a resolution into the file header? or is it just so many rows by so many columns of pixels?

Well, it’s not that I necessarily want to do this on my own machine. However, as part of a workshop series, I demonstrate a digital camera and then open the images in Photoshop. I’d just rather not have to try to explain why the images open at 72ppi instead of something else, why they’re so big inches x inches, and how to change it. This is a very basic demonstration and there’s no need for the students to be learning Photoshop at this time. Just saves me answering a bunch of questions. So if there’s a way to change it, that would help me out.

Hi Sid
Seems like the easiest solution would be to set your camera’s image size when taking the photo. For smaller sizes, I set my picture size to 640 X 480 pixels. This equates to an 8 X 6 picture.
