Bit of a weird question.

At work we use these basic PNS cameras, they've been fine until recently. A lot of the local publications that we publish in have updated their software to high def or something - I don't know the nitty gritty, just from what I gather - anyway, now our images aren't up to scratch with what they need, and are printing out grainy and no good.

Does anyone know how to change the resolution in these cameras? I thought I knew how to do it, but it's proving difficult. :confused3

I've changed and played around with the pic quality/size option, but it doesn't look like it's doing anything when I check the resolution of the resulting image...

Any help would be greatly appreciated, because for some reason the boss seems to think I'm the one to fix it, :confused:

You said you've adjusted the size of the image with the quality... that is the resolution. I'm guessing maybe you mean DPI? Cameras are usually 72 DPI (or PPI) and you can't change that. It's irrelevant anyway. What matters is the actual pixel dimensions of the image. DPI is just a translation from pixels to inches.

There was a whole thread about this not too long ago on here, wasn't there?

If your images are grainy it could be digital noise. Usually low resolution comes out pixelated and blocky.

I think DPI is what I'm referring to, like I said, I'm just going off information that's been passed on to me by the people who are having the problems. I'm really just the middle man... :confused3

My camera shows up a DPI of 96, but apparently the publishing companies need them to be a minimum of 250...

So how do we change that if it can't be done on the cameras?

First you need to make sure you've got the pixels there to have a 250 DPI image at whatever size you want to print.

inches x DPI = pixels

So take your desired print size and multiply it by the required 250 and that will tell you the minimum pixel dimensions you need your image to be.

You can change the DPI in many photo editing programs. Are they wanting things sized exactly for print? Because that takes a little bit more than just changing the DPI.. though not much more. Otherwise, just make sure you've got the minimum pixel dimensions at least and it should be good to go.
