300.....
« on: August 07, 2005, 01:14:53 PM »
Hi everyone....

a quick question from a newbee: I only get 72 dpi from my shots even with extra fine large files... I need higher res (300dpi) and I just cannot find how to set the cam... someone can help? Thanks.

You can't, as far as I know.
Not on the camera, anyway. You'll have to do it as  a part of post-camera processing, on a program such as Photoshop.
On Photoshop for example, go to Image--> Image Size--> Once the dialog box opens, under "Document Size", change Resolution to 300 or whatever else from 72.
This will also change your image pixel dimensions.

Thanks, I know that trick in Photoshop, though I do not understand that such an expensive digital camera does not record at 300dpi since a cheaper crappy one does...

All digital cameras capture at 72dpi.  Remember that DPI is a relational thing.  Dots PER inch.  Look at the physical size of a photo at 72dpi, you wouldn't be able to find a printer that went to that size.  A raw 7D image at 72dpi is 106 x 70 cm.  about 3ft x 2ft if you prefer imperial.  

What you need to do is resize the image to be 300dpi.  This would give you a 25.47 x 16.93 cm.  A4 is 29.7 x 21.0, so a nicely boarded pic from a 7D.

This is the case for ALL digital SLRs.  Including the £5000+ Canon 1DsII.

I hope this helps.  You can download images from the Canon 1DsII from the Canon website if you want to see that even the pro dSLRs are the same.

Hi Guys & Gals,

Is it possible to increase the dpi from 72 to 300 using DiMage Master, or will I need to buy some other software?

Cheers,

Zack
