Hi jtp,
I'm a jpeg shooter. I'm mainly a birder, and camera performance is important to what I like to shoot. I've been shooting Pentax DSLRs for over 5 years, have tried RAW numerous times with 5 different bodies and at least 5 different RAW processors, and haven't found a compelling reason to sacrifice the extra performance I get from shooting jpegs for the marginal increase in IQ that I might gain by shooting RAW
for my purposes. Shooting RAW is always slower, and when I need the speed, I want it available without any extra steps or even thinking about it -- even the RAW button convenient as it is, is too slow. I'm not an ultimate performance junkie (I shoot Pentax, after all
), and I've never posted in any of the fora nagging Pentax for more speed, but I'll take what they give me, and I do tend to push the performance of my Pentax DSLRs to their limits frequently.
I'm an amateur/hobbiest and my target output medium is usually prints, mostly 8x10, but most images can be taken to 16x20 with a little extra attention in PP.
RAW will allow more latitude for exposure, color balance, and noise processing, but jpeg processing is not that far behind when the camera image parameters are set up to my preferences and the exposure is within reason. I'm sure that RAW shooters will disagree here, but most arguments for RAW are based largely on theoretical models and pixel peeping that in actual practice doesn't show up in prints, with the possible exception of extreme enlargements that I don't do.
I also shoot a large volume of images per shoot (probably as much as ten times the average on this forum from the shutter actuation counts posted in the threads I've seen), and the cumulative time spent on just viewing these just to choose the shots I want to process and print from RAW images would be prohibitive for me, and I spend a lot of time on photography.
The argument about the tiny in-camera processor for jpeg doesn't fly for me. The processing engine in the camera has one function -- to process images. It's very efficient at what it does, and this gets better with every generation of cameras. Ask yourself why
all camera mfgs include jpeg processors in their highest end Pro models, and why they would include more sophisticated image tweaking features in the pro models than the entry level ones when these have no effect on RAW images captured. I'm sure that leaving the jpeg processor out would save them considerable money, and would clean up the menu systems dramatically. I don't expect to ever see a RAW only model at any level. Also consider that the jpeg engine in your camera processes RAW to jpeg faster than any desktop computer/RAW processing program I've ever used, and speed specs ( sustained frame rate, write times, and buffer saturation) always are indicated for either jpeg or RAW, and jpeg is always faster.
I'm not advocating jpeg, and I'm not advising against RAW. If there wasn't a significant case for each, this would not be an ongoing controversy. I suggest that you try both and decide which is right for you and what you like to shoot. I always think that this question needs at least a few posts defending jpegs, since there seems to never be a lack of RAW supporters.
For me, jpegs work (and I even shoot mostly at *** instead of **** which is available in my K-7 and K-20, as I haven't
seen any appreciable image degradation or compression artifact difference between the 2 quality settings). As in everything about digital photography, YMMV.
Have fun with your camera, discover incredible stuff it can do, and I'd suggest that you make decisions on procedures based on what you actually can see, not what's theoretically possible -- photography is a visually based thing, not a mathematical model.
