 ID: 183878 Posts: 1387 | Date: 2007-04-20 08:03 Not a bad little camera. Try to avoid going higher than 400 ISO because it tends
to be noisy, but if you really need it the camera will go to ISO 3200 for dimly
lit scenes.
It does have a (flower symbol) Macro setting and the lens will probably also
have an indicator as to which part of the zoom to use for macro, although I
don't know for sure as I could only read a review.
And it has an AV setting that will increase or decrease the shutter speed
automatically as you set the aperture value higher or lower.
Get a tripod and a cable or remote shutter release and you are ready for basic
macro work.If I haven't been there, I'm still planning on going!

focus on the fourth ring of the shell. See if that works.If I haven't been there, I'm still planning on going!

 ID: 185837 Posts: 336 | Date: 2007-04-20 08:10 Best way to experience depth of field:
Take two pictures of something large fairly close, one at the maximum aperture
and the other at the minimum. Compare the difference. The joy of digital is that
you can do this right away.
A hedge, railings or flower bed are all good examples, just make sure they are
running away from you. Make sure you focus on the same point for the two
pics.
When you zoom into 100% and compare you will really notice the difference.***** Spring approaches and soon the fairies will awaken ***** |

choose the little flower mode i feel that the less it's automatized the
better |

balance in Photoshop to some degree.If I haven't been there, I'm still planning on going!

 ID: 154201 Posts: 187 | Date: 2007-04-23 03:07 DOF is something like the rest of the picture excluding the subject that is
clear in or out of focus. If everything is sharp it might be distracting. If
stuff's that's not in focus that's being blurred out you may have insufficient
details of the surroundings. That's what it is. |

love it, i also have some other film and Digital SLRs too, but I love pentax,
they're the underdogs and I am never disappointed with them.
If you find that too much of your subject is out of focus, you want to widen the
depth of field, and you can do that using the Aperture.
I know this has probably been answered, but I'll throw in my 2 cents since I had
the same issues when I first started out.
a wide open aperture (small f/stop) will make your DOF small, so what you want
to do is stop down on the aperture (raise the f/stop number to something like
22) and then compensate for the decreased amount of light by leaving the shutter
open longer.
If you want to try a close up shot, try one of the good reversing rings for your
lens, a buddy of mine has one and the results aren't bad at all. I use a 200mm
zoom lens with macro mode if i feel like shooting macro, but I need a tripod for
that 
Hope that Helps

 ID: 190301 Posts: 20 | Date: 2007-05-08 12:55 The closer you get, the less DOF you have. This has always been a scuorge to the
photography industry. You can try a wider angle lens, but that's gonna put you
closer to the subject, and make the subject seem further away. It will also
cause more perspective distortion (dognose effect to the NYI grads).
Have fun and keep shooting,

 ID: 190390 Posts: 174 | Date: 2007-05-17 11:17 Higher F stop equals longer depth of field, shorter lens equal longer depth of
field. As your F stop decreases to a smaller number and your lens lenthens an
18mm vs a 400mm the depth of field (the amount in focus gets shorter) |

Aperture.
Your best friends should be Av and Manual mode.
Av mode is great for metering deciding what you want the shutter speed to be and
then increasing it or decreasing it depending on your taste.
Manual is just great because you can do whatever the hell you want
Also here's an example of nice DOF control, her face and the top of her chest
are in focus and then the rest is out of focus, but it keeps attention on the
eyes

 ID: 190050 Posts: 4 | Date: 2007-05-24 04:05 To summarize, DOF depends on 3 factors :
- The aperture : wider equals shorter DOF,
- The focal length : longer makes a shorter DOF (at equivalent aperture),
- The size of the sensor : the bigger the sensor is, the shorter the DOF will be
(at the same aperture).
