Blur the Gackground ??

[siron]

I like shots when the subject is focused yet have a VERY blur background... HOw do you actually adjust the settings? While taking such shots...is it for days better?? And do you use the flash for such shots??


Thanks!!

Reduce the f-value as indicated on your cam dsiplay, to the smallest possible given your DC or lens(for film-based cam users); in short the smaller the value, the blurrer is the background!

The further the subject away from the background increase the blurness too

To add to what adam said, besides setting the widest aperture, also don't forget to use the longest telephoto zoom and move your subject as close to the camera and as far away from the background as possible.

Hi,

Note: It is VERY HARD to get a good blur background if you are using a consumer digital camera (e.g. G1/2, F707, 99x, etc). This is because the inherent depth of field of such cameras is very high due to the small sensor and relatively 'wide' lenses used. So you can only maximize the effect by using the telephoto end of the zoom and as big an aperture as you can get.

Sorry but can you tell me what do you mean by using the telephoto end of the zoom ? Is it zoom to the fullest??

Yup, zoom in all the way so the objects appear the largest.

like this??

taken with F707

F3.5 (should have use F2 instead)
ISO 100 (should use high or low ar?)
EV -2
no flash
macro mode (heard that macro mode can increase DOF)

For the above, i have to admit that i use PS auto level to increase the DOF a bit and to make the object look like poped out of the screen (similar effect of using slide?)

paiseh huh can you elaborate what you meant by using auto-levels to increase DOF? Me a bit puzzled.

 

[eadwine]

from what i know...u use higher iso when its low light and brighter lights u use lower iso.....
am i right?

to my knowledge, auto-levels will only adjust the levels in the image. The difference in DOF may be just an optical illusion.

One way to make DOF more shallow using photoshop is masking then gaussian blur.
