| I've read the wonderful tutorial, but I'm still uncertain how to go about shortening the DOF with the digital when shooting in broad daylight. I'd like the subject only in sharp focus. Adjustments made so far help, but not enough. Maybe it's having a weak camera. Here at work I shoot with an Epson Photo PC 150Z while lobbying for a Canon G2. Any suggestions? |

i don't know much about the camera you are using... if it has aperture priority mode, use that and set the F number low.. like 2.0 or 2.1 or something small...
if you don't have this level of control, try using the zoom at maximum zoom range... this sometimes helps :) |

| Thanks, john. I'll try the zoom trick and re-read the manual on this baby. It's an older camera and not real intuitive. I've been manipulating backgrounds in PShop, but would prefer to get the shot out of the camera! 'Preciate your help. |

If you are using photoshop, a neat trick is to cut your subject out and then apply a gausian blur to the remaining part of the image, then paste your subject back in... or some similar procedure with layers..

make your aperature as big as you can, if you have control over this.
however the prob in broad daylight is going to be you'll get to much light. so you have to speed up the shutter a LOT.
if you're shutter won't go fast enough to hit the biggest aper in daylight, you can get a neutral density filter, which is essentially a piece of gray glass that cuts down the light hitting your sensor. I have to do this when i want shallow DOF in bright light, because my max shutter is only 1/640 s.
If your camera won't take filters you can tape or hold an ND filter over the lens if you want to be macgyver about it.. otherwise you may be out of luck... |

A filter will NOT change your depth of field. :)

this can work, pretty well, although it can also look kind of fakey, esp if there's a little fringe of good focus right around the perimeter of your subject.
here's an example of where i used that technique to blur the bg:

no, i said a filter will cut the light hitting your camera so you can use a wider aperature in brighter light situations :)

Why''s there a little spot of blur at the pavement/brick line in the lower right?

Hehe. I thought it was some new 'spot blur' artistic element that I was missing out on...:-)

| Yes, PShop's gausian blur has been getting a workout! I find it also helps to silhouette the subject and lighten or dark the background a bit to make the subject pop. I am trying to eliminate, or reduce, reliance on Photoshop and get a better image out of this "toy" camera I've been handed. (Can you tell I don't care for it much!) Or maybe the poor results are ... (big gulp) entirely my fault. |

The DOF has an intimate relation with the aperture you set the lens to. The lower the number, the more light it captures and the less DOF you get. Also try using the zoom all the way in, even un close objects. If you have to get back a little, do it. This is the best way to get what you want, although I must say that with digital the effect is less dramatic than with a SLR.
I imagine you have problems because you pictures get too bright because of the wide aperture? try using a lower ISO (50) or sub exposing if that is possible with your acmera.
Hope that helped.
