Originally posted by Lowell Goudge If you take your time, and actually learn the jpeg settings, and adjust your settings for the situation, I.e. contrast, hue, WB, highlight and shadow detail protection.... RAW offers very little advantage because you are already so close that there is no need for further adjustments.
While I agree with the fact that the RAW advantage ends-up being a subjective one in the end. I'd posit the following simple experiment:
Take a picture inside a house with a window in broad daylight and adjust your JPG settings so as to properly expose both the room and the window.
The simple fact of the matter is that most current in-camera processing engines do not take full advantage of a sensors capabilities. Which is pretty strange to say the least considering the advancements that have been made over the past few years, Having said that, this phenomenon(of untapped performance) seems far more prevalent today than ever when we consider the recent developments in sensor performance and so in some ways, I think the advantages of RAW processing has gained considerable ground toward this issue.
With that in mind, there are other benefits to shooting RAW than just dynamic range:
- Demosaicing
- Lossless compression
- Noise and grain quality
- Sharpening performance
- Color depth
Granted, some of these may seem like they fall in the pixel peeping category for some people, however, as a long time RAW shooter, I can testify that the advantages of RAW reach far beyond that of rescuing photo's. For example; I've found that though the OOC images from a K-5 can be deemed adequate in many situations, that achieving that 3D could only be accomplished with RAW.
Having said all that, there is another seldom spoken aspect to shooting RAW that seems overlooked by many people. And that is where we find ourselves processing JPG images when all is said and done. Which is rather redundant if/when you think of it as we find ourselves doing the same amount of work without any of the benefits.
And so in many ways, I think there is much to consider in terms of feature and benefits between both approaches.
PS. here is a simple case study carried out with a K-5 I did about a year ago which touched on the issue of post processing a JPG vs a RAW file. granted, I could have used spot metering to expose for the highlights, but... that would have meant pulling-up shadows at the expense of IQ as a result. And so in this particular case, the RAW advantage became obvious:
K-5, 200mm f/4, OOC JPG W/adjustements K-5, 200mm f/4, OOC RAW, ACR 6.2
