Background blur?

[grass]

From what the guide says, all I'll have to do is set the camera to portrait mode and click the button.

This doesn't seem to work. What am I doing wrong here?

Thank you,

You are not going to be able to get the kind of blur you will see with an SLR in my experience anyway. Your best best to use manual or Av mode and set the aperture to f2.0 for full wide or f3.0 for full tele. If that doesn't blur enough then you can try doing it with the Lens Blur filter in Photoshop CS. It does a pretty good job.

Thank you Darryl. I'll give that a try tonight after work.

Grass,

I think you might get good results (not quite like an SLR, because of the much smaller sensor size) by trying the following:

Set the camera to Macro mode, then get *close* and open the lense as wide as possible. VoilÃ* - blurred background!

Example:

Subect three feet away, F4.5 1/250, Macro mode, Zoom (focal length 25)

PS - sticking a teleconverter up front *really* helps too

I think other inmates have also posted this website as a reference: http://209.196.177.41/03/03-03.htm. It talks about the relationship between DOF and aperture.

Perhaps I should have checked to see that both aperture threads were by the same poster. Apologies warman and thanks for the link.

:idea: In order to get a nice background blur you have to get sufficient distance between the subject and the background. If the subject isn't far enough from the background, it won't be blurry enough. That's all it takes.

The best and easiest way to get background blur on a G3 is to use Macro Mode, zoom in close to your subject and make sure there is some distance between your subject and background items.

like I said

Thank you everyone for the replys. I'll give this a try later on, and be sure to post my results.

Sorry about the double post on the same subject.

Quite easy! Just spend some between $ 3,000 on a 10D and the EF-300/4.0 L lens and $ 6,000 (same camera, 300/2.8 L) ... not sure which of these lenses Ian has, but that's what he used to get that photo.

To understand the relationship between DOF and aperture, you also have to know that the sensor size in Digicams is a lot smaller than in DSLR's. For that reason, your f/2.0 is actually a f/8 lens, as far as DOF is concerned -> it is NOT possible to get the same effect from a DSLR on a digicam.

So you have to use the macro mode, which is some kind of workaround and involves using a different focusing in the camera. However, the basics stay the same - take a long focal length (G 5 fully zoomed in) and see that there is a lot of distance between your object and the background.

Or, use the 'Background blur' filter in Photoshop.

Best regards,
Andy

Thanks Andy.

I have yet got to this work. The rain has been pretty bad around my area, so I've been stuck inside. Last night I gave it a try inside with a box of 'Gold fish' (the snack). Not luck! :lol:

:lol: That's a thought, take your pictures under water! Then the background will automatically be blurred. (just a little humor)
