If you use pbase go to your photo, pick the size medium, large or
original, right click the photo,choose properties and you'll see
the link then highlight the link then right click and choose copy
then post a message and right click and choose paste in the message
box with your message.

And if you want the picture to show up here, not just the link to
pbase, add .jpg to the end after you paste.

My aperture doesn't seem to want to go any lower than a 2.8 but
that doesn't seem to work for blurring background shots. What is
the best settings to use to do this to take picture of flowers as
single group and/or single flower? Thanks

It depends on how much bluring your trying to get. Here are some
examples that were shot at F2.8, spot focus and spot metering.

WOW!! HG I love this one...



I didn't know that one was on here. This is the one I would like to get some backgrounds like. This is really amazing.

The problem is really with all digital cameras...the F-stop on a
digital must be multiplied by the focal lengh equivalence of the
camera...ie.

the 2100UZ's actual focal length is 7-70mm which is said to be
equivalent to 38-380mm. The focal length equivalent factor is
7:38; 70:380

or 38/7 = 5.4 usually rounded to 5

soooooooo.... f2.8 is actually 2.8x5 or f14..... WOW...that means
f8 is actually f40!! WOW WOW!...well it doesnt exactly come out
that way, but close... see this article..

NOW!!

To really blur out the background...say like this...with floral
shots or insects..

You have to use the zoom and/or the macro...which means you have to
be within 3-6ft of the subject.

Hope this helps...

the background like the one on the pink flower was exactly what I
want to get sometimes the dark (black background) and the
subbackground blurred. That's a wonderful picture.

I am new in taking photographs. Used a 3020 to shoot the above pic
to achieve a slightly blur image of a not so far object. How is it?
