You may also want to try this codec pack: FastPictureViewer Codec Pack for Windows 7, Vista and XP.
that way Windows Explorer and Photo gallery will also support viewing RAW files.

I just took a look at the site and it seems it is not free anymore(9.99$). I was lucky to get the free version some time ago. Oh, well :(

K20D and color please?

I don't think there is something wrong here. You have to remember that at 180mm and f8.0 the DOF is still shallow. Check Depth of Field Table! I do not know hoe far was the subject, but for example if subject distance is ~5m, then DOF @ f=8 will be only around 20cm!

Post-Processing Ethics

I think I am a minority here. I chose to shoot JPEG. Tried RAW+ (camera records both RAW and JPEG) for some time. Did not find any advantages in RAW over JPEG (quite contrary) for my shooting style.
My suggestion, try RAW+ for some time. Then decide if you really need RAW overhead.

A theoretical question. What if in case of APS-C sensor, we move the sensor closer to the lens, so that the whole frame is "filled" (see edited illustration in attachment)? Seems to me, everything should be the same as in case of FF sensor, or shouldn't it?

"Raw to Jpeg" color different in Camera output and Pentax software output

From my short experience and experiments with RAW, Pentax supplied software seems to have a closest match to camera JPEGs. It seems to me that an absolute match to camera processed images is not possible to mimic. I am also disappointed by this fact. Have tried shooting RAW+ and then compared camera JPEGs to post-processed from RAW and there has always been a difference. In most cases I could choose from RAW processed JPEG, but there a times when I will notice that camera JPEG is actually better (finer detail, color gradients).

Unfortunately, pro-RAW people will never tell you that :). It is always about compromise whether you are shooting RAW or JPEG.

DCU4 for K20D owner

I actually made an ISO image and them mounted it as a virtual CD-DRIVE. All worked. During installation there was a message to put an original installation CD (supposedly the one that comes with newer cameras), I just clicked "OK" and installation went on just fine.

How much is really required?

My suggestion is to try LightZone. It is very capable, though maybe the whole approach to editing is a bit different, but once you get it, I think you'll like it. I am currently still in trial period. Currently I am considering buying it (only $100, compared to competitor products). One more thing I like about it very much is a lack of some sort of "collection" functionality. So, you do not risk having your collections incompatible with new release of application.

I was wondering if it is possible to get a DIGITAL CAMERA UTILITY 4 for me as an owner of K20D camera? I have had a bad experience with PPL/PPB 3 and was hoping to get my hands on DCU4. But apparently only the owners of newer camera models have the privilege of using DCU4.

Favorite exposure modes?

Since I purchased my K20D I have been shooting mostly P and Av modes. Recently I am shooting more and more M with spot metering, which is slower, but seems to be giving me more control over exposure and I have noticed, that my exposures are better. When shooting in dynamic environment, will choose P.
Also, lately I have been looking into TAv.

This sound like a good read. Though, I don't think I can get my hand on this magazine any time soon.

There are two conclusions I have come to reading comments to this thread.

1) My frustration with shooting RAW most probably is due to lacking knowledge and skills with PP software (which in turn is caused by lack of time). Basically, my inability to come up with own presets which later-on could be applied to multiple images and decrease time for PP.

2) I am frustrated that PP (I am not talking here about PP that happens automatically in-camera after shutter release) has such an important role in photography, or more precisely on the end result. I will try to deal with that. This is my problem. :)

3) I am still willing to do 99% of the end picture in-camera, e.g. correctly choose WB, exposere, framing etc. and not rely on RAW to correct mistakes that should not be there in the first place.

Apparently you are right on this. But as a hobbyist I simply don't have that much time to kill sitting at my computer and fiddling with each and every image I shot over the weekend. i understand that there are peapole who earn for living with photography, and they have a luxury to kill whole 8 hours just PP their images. This is all OK. But me, I simply have 2 days over weekend and evenings after work. And not all of that time I can dedicate to my hobby. In the end, what is left is very little and I prefer to spend that time actually doing photography instead of sitting at computer ... again :).

OK, just a little example from life here. Suppose you are a RAW shooter. You get home with a memory card full of images. Some of those images are really special and might need that special PP touch. No problem here, you just do that PP magic on those images. BUT, you still have the rest 90-80% shots that need to be processed from RAW to something ... well not RAW. As I have learned and people in the thread have mentioned, default setting in RAW converters will not get you far. So, you do that PP magic you did on those really special keepers on the rest. Going through each and every image and carefully tweaking settings. You could say, well there is a great feature where you can copy/paste your PP "recipe" from one to multiple images. But in most cases this will hold true only four couple of images, because others - they are bit different and requite different tweaks.
Guess what, it is Monday morning 4am you are done with PP, go to bed because at 8:00am you are off to work. :)

Hi All,

You might say that I am new to photography, just some ~2 years of more or less hobbyist shooting. Only a year with my first DSLR which happen to be Pentax K20D. During this time I have been reading lots of posts on internet about how good is "shooting RAW" and how it can save lots and lots of problems in post processing. I have been trying to adopt this myself e.g. shooting RAW. Here are some of my humble thoughts about the subject (be warned though, this is totally biased and from hobbyist point of view).

Generally speaking I am disappointed in shooting RAW and here is why:

1. None of the PP software delivered results I was hoping to see. I tried Lightroom 2 and 3 betas, RawTherapy, Capture One 5 (PRO), DxO. What I was hoping to see was something substantially better than what my camera delivers in JPEG. In most cases I was disappointed either by demosaic algorithm (Lightroom actually does it very well) or by loss in details or by tonal color transitions (out of camera these are usually smooth, compared to harsh transitions in JPEGs exported from RAW in PP).

2. Sure you can save otherwise seemingly lost shot by correcting exposure or white balance, but result will not be great. You should have made the shot right in the first place by choosing correct settings. Save yourself time and just discard the lost shot. Learn from mistakes and do it right next time! Relying on RAW PP will not teach you anything.

3. I do not understand how my little camera can process RAW file to JPEG in less time and deliver better results than my Dual core PC with latest RAW PP software. I mean, to make RAW -> JPEG conversion in camera it takes what - 2-3 seconds, in Lightroom 5-10 seconds, in Capture One 10-15 seconds. What is wrong here?!

4. The only case where I would shoot RAW is high ISO images. Lightroom does a really nice job producing pleasant looking results. But at the cost of lost details. This is compromise anyway. Out of camera images are noisier, but at the same time details are preserved better.

Sorry, that this was a bit lengthy, but I am really frustrated that I have lost so much time trying to shoot RAW and have gained absolutely nothing in terms of image quality. Apparently this is not for me. I really dislike PP.

But I still wonder, how it is possible that tiny little camera does the job better that a modern PC?

I hope this can be helpful to some who are exploring subject of RAW vs JPEG and are reading only how good is shooting RAW. Of-course, I realize that there are people who only can afford shooting RAW (pro photographers?), but for hobbyist ... I would think twice.
