ok so it is better for post processing.. but what if I have NO CLUE what I am doing so I can't fix the pics am I better off not using RAW? Do you need to use camera specific s/w for pp? Like I use Linux... so if my camera comes with windows or mac s/w am i SOL?

There are options for Linux users (Hopefully, JimC will chime in here.) but they are limited. You do have some latitude when working with JPEG files, so you can correct for minor problems with exposure or white balance, but not as much as when working with RAW. If you anticipate having to do a lot of post processing, the tools and options for doing it with RAW files tend to be very different from those for JPEG files, so your experience JPEGs may not transfer when you start working with RAW. If shooting RAW doesn't get in the way of other things you want to do, and you can find suitable tools for working with RAW files, you might want to stick with RAW for a while just to see how it goes.

If you shot in jpeg, you let the camrera do the processing and compression, but you can also do small amount of process on jpeg files if you do not want to get to into post processing.

I have shot both raw and jpeg + raw/jpeg with my A-700 and all the lens.
I rarely see enough difference to merit the extra space that raw consumes and in some cases, the jpeg even looks better than the raw version.
I have reverted to shooting jpeg only and haven't missed any shots due to exposure or color. I have missed focus a few times in sports but hey, I have no clue what I am doing.

Nope (you're not SOL). I rarely use a camera manufacturer's software for anything.

For starters, look at digiKam 1.0.0 in a free option for converting raw files, managing your images, performing a number of image enhancements and much more.


Digital Imaging products for Linux are coming along quite nicely now. For example, I use digiKam for a lot of tasks (managing images, cropping, usm, refocus algorithms, resizing, curves, etc.). It's an easy to use photo management solution with lots of good editing plugins available (make sure to install the latest kipi plugins, too). If you're not familiar with it, see page for more info. If you look under the About menu choice, you'll see links to an overview, feature lists and more.

http://www.digikam.org

Make sure to install showfoto, too . It's got most of the same functionality that's built into digiKam, except that it doesn't have the album related features. I keep both installed in the Linux distros I use.

Krita is also coming along nicely, and it's well integrated into the KDE Office Suite.

http://krita.org/

Another product worth looking at is Lightzone (commercial, but now available for Windows, Mac and Linux operating systems):

http://www.lightcrafts.com/lightzone/

Eric Hyman also offers Bibble for multiple operating systems (Windows, Mac, Linux). Bibble 5 Pro was just released, and it's really slick software.

http://bibblelabs.com/products/bibble5/

Google's Picasa is also available for Linux:

http://picasa.google.com/linux/

Make sure to see Raw Therapee (also available for Windows and Linux). It's free.

http://www.rawtherapee.com/

For imaging editing, make sure to look at Cinepaint, too (it supports 16 bit editing and more, where the Gimp is limited to 8 bits at this time, although work is well underway to support higher bit depth editing in the GIMP).

http://www.cinepaint.org/

You can also run a lot of Windows applications under Wine. I've been pretty surprised at how many applications run fine that way. I even have multiple versions of IE installed in Wine, so I can check to see if a given browser version has problems with a site, without running Windows to find out.

You can also run a copy of Windows in a Virtual Machine under Linux if you absolutely need something that won't run in Linux or Wine. I'd look at the free Sun Virtualbox for that purpose. It's coming along nicely:

Jim,
Thanks for ALL the useful info.. I use digikam, and gimp... I will look at the other progs... good to know that a lot of stuff works under WINE... I gave up a long time ago on wine... when it didn't work so well.. maybe time to relook into it...
Thanks again

Bibble looks pretty good to me.

If it had been this good 18 months ago I might not have joined the Lightroom fold.

Yes. I've been very impressed with Bibble 5 Pro. I especially like that it's cross platform, too (Linux, Mac, Linux), since I run both Windows and Linux on my PCs.

Here's a good example of why RAW is so important. While shooting a wedding, my flash unit started outputting at about 1/2 power. I didn't notice as I wasn't chimping (looking at the LCD to see the quick review of the shot I just took), and I saw the flash firing.

Here was the final JPEG. Luckily I was shooting in RAW+JPEG, so I was able to salvage the shot, and produce this.
Name:  raw_e2.JPG

Not perfect, but much better than the above shot.

BTW, I also use GIMP, however the UFRaw plug-in still isn't supporting the EOS 7D (although they have it listed on their site). So, I installed the included Digital Photo Professional Canon software on my WinXP VM, and used that to convert the RAW. DPP works very well, and I was pleased with the outcome.

I use this setup on a daily basis. Runs flawlessly, and I'm even using an older version of Vbox.
