Which pp set up is best, K200D

I apologize for asking this but I am so confused by all the different permutations for processing raw files. I had a copy of Adobe Lightroom 1.4 (education copy) which I lost in a recent house move, but I never used it, far less understood it. I can pick up a copy of ver 2.0 for £75 but I wonder what users on this forum would recommend. Is the bundled K200D software fine for someone like me who does mostly jpeg but might want now and again to shoot raw, and if I see a big difference move might over to shooting raw all the time.
Is one of the free convertors like raw therapee as good as anything ?
As of present I use Picasa 3 for jpegs and am quite happy with it.
Link is to my flickr page where everything is jpeg and done in Picasa, would I benefit from raw ?

Hi Donald,
Use whatever works best for you
If you're getting results out of JPG, then carry on
Picasa 3 is great for basic fixes.

Here's a quick run down of stuff I've used:
1. Bundled Pentax software - based on the Silkpix engine. Very good image quality. Limited control over RAW (but more than Picasa)

2. Capture One 4 - nice UI. Good image quality. Was bundled free with Sandisk III cards last year...

3. Silkypix DS 3 - best image quality, especially for high ISO images. Incredible control over colour. Probably best to wait a while for version 4 (which is due soon!) before buying. BUT there is a free version which gives a bit more control than the Pentax software

4. Lightroom - I quite like the GUI for Lightroom (v1). Control over exposure is excellent. But the IQ for high ISO meant I ditched it (again )


The best thing with RAW is you can use Picasa, the bundled Pentax software, or Silkypix free - if you find you've hit a "ceiling", then you can purchase something later and reprocess any wanted RAW files again

HTH!

raw therapee works for me

I use the bundled Pentax software. Not the most intuitive I've ever come across but once I got used to it I find I rather like it.
