PostPosted: Wed Feb 27, 2008 9:45 pm 
Hi! I'm an apprentice photographer and from some time I've asked to myself... How can I take picture like my little compact with my Dslr. Don't know if you understand what i mean, the dslr make blur on the background and the compact take every subject on a picture.
Thx for responding and good picture shot

The issue you are talking about is called "depth of field" (or DoF). I recommend you read this article first so you know what it is and how it works.

Basically, if you want your pictures to look similar to those of a compact camera, you would want to have a high f number (f 22 should be fine). However, a high f number will reduce the size of the aperture, hence then quantity of light coming in - be sure to adjust the shutter speed and iso accordingly.

Hi Peace-Warrior,

I recently discovered a nice online Depth of Field calculator (here) which includes a huge range of compact cameras in its database, as well as DSLRs, so that should allow you to work out the equivalent settings for your compact.
