I have Elements 6.
I import my photos directly into the organiser. Then I back them up. Even the duds (you never know when they might come in handy).
I then sort through and decide which ones I want to work on. By opening a RAW file in full edit you automatically come into Camera RAW where you can do the initial tweaks to the photo. Try playing with it yourself and see what you like best. You can change the white balance here as well as lots of other adjustments. Do not touch the saturation slider, but do try the vibrance and clarity sliders. If you have a lot of photos taken at the same time you can do a batch conversion by selecting them and then opening them all in camera raw, and again selecting them all. Whatever you do to the top photo will also be done to the rest. If you find you are always using the same settings you can save these, page 224 in MM tells you how.
You can also crop in camera RAW, and do some initial sharpening if you wish.
In full edit I then do further things like levels, etc and sharpening, though I don't sharpen all my photos. I save them as jpegs since Tiffs are huge and I don't have the room for them. You can try the auto settings first if you like, but generally doing it yourself is better.
Since I have backed up the originals I don't save the converted RAW as a set version with the original.
I'd suggest starting with a photo you are happy with but which isn't a keeper and just play with it to see what everything does to it. Who knows it may turn into a keeper

If the screen tilted live view would be more useful, but with a fixed screen, and the clunky Pentax system it isn't really that useful. It is the one thing which Sony (and Olympus?) have got right, shame about the rest of the camera .
Tethered shooting (using a laptop) is probably more useful, if you want to carry a laptop everywhere. Since I lug enough weight around with just my camera gear a laptop is not about to be added to the list, not even a netbook.

You have a PM.

The CRV3 is also the battery recommended by Pentax for the Ist Ds, with rechargeable AA and other AA batteries as second and third choice. They are great batteries and last for ages. It does seem a shame that Pentax redesigned the battery compartment so you can no longer use them.

Have you loaded the Pentax software which came with the K20D or are you relying on that which came with the K10D?
Every camera has it's own version of RAW even within a manufacturers range, so the PEF files from the K20D are not the same as those from the K10D and you will need to update the software, or use the Pentax software you got with the K20D. As Terry says you will need to update editing software you use to read the PEFs from the K20D. No doubt there is a similar update available for the basic Apple viewing software, though I am not familiar with this - my Vista machine manages just fine with it.
Try downloading Irfanview if all else fails - that can read K20D PEFs.

Welcome to the forum.
I made the leap from the Ist Ds to the K20D, and haven't regretted it for a moment!

At the bottom of the page(right at the bottom, next to the terms of use)is a report problem form. Try using that - they accept suggestions on it as well as problems.

Stefan, it depends on the shot - sometimes I will calculate, sometimes it's pure feeling - so my neutral stand is at work again .

I do prefer dogs to cats though - wasn't there something about liking dogs in the description???

40% left brain, 60% right and I can make her turn both ways so I guess that makes me neutral

Edit: but it doesn't help my spelling
