I just bought a digital camera. Low end, the cheapest I could get, so I can take pictures for my job. Anyway, my employer’s specifications are that I need to upload them to photos at 72 dpi. I called tech support on the camera (hp) and all I got out of it was that there’s a function to e-mail the pictures and I can select the dpi through that (apparently).
Unfortunately, what I have to do is go to the website, click on upload, and select the pictures off my computer, so I can’t use an e-mail interface like hp told me.
The pictures are automatically taken at 200 dpi…I tried taking them at different qualities (good, better, best, camera settings), but they’re all 200 dpi when I look in photostudio.
What’s the best way (and preferably free) to change the dpi. That is, is there somewhere I can download a program, not pay for something, or am I just missing a function in my picture editing program?
I haven’t dealt with image size manipulation much, but I’ve noticed these last few years that printers and scanners often have DPI specs that are asymetrical.
For instance, my HP printer does 2400 x 1200 DPI and my scanner does 4800 x 2400.
Cameras do not take pictures in dpi. They take pictures of given pixel sizes: e.g., 640x480, 800x600, etc. Since monitors vary in size, dpi also doesn’t make any sense when talking about video display. dpi only makes sense where an inch is an actual fixed size on a piece of paper. E.g., in the context of printers and scanners. But keep in mind that 800x600 and and 640x480 pictures can both be printed at 72 dpi. The size of the images on the paper will be different. (In fact, the 800x600 won’t fit on 8.5x11" paper.)
In other words, saying “A picture has to be 72 dpi.” means the speaker is an idiot and doesn’t know the basics of digital images. I’m serious. This is Dilbert-world-speak.
I’m wondering though, it’s asking for a number x a number for dpi, not just a straight number.
