1. Re: Editing JPEGs with the RAW interface
dj_paige Mar 23, 2010 11:40 AM (in response to Deep Woods)I agree with most of what you said ... but I never heard "...you're only suppost to use Levels Hue/Saturation controls once", and in fact, I don't think that is correct. Could you explain more, or give a reference?
Perhaps you are referring to the fact that each time you save a .jpg, the image degrades; whereas you can go back into Adobe Camera Raw and edit your JPG again without image degradation that comes from saving a .jpg. If that's what you are referring to, then this is a well-known consequence of the non-destructive editing that ACR performs.

2. Re: Editing JPEGs with the RAW interface
Deep Woods Mar 23, 2010 12:46 PM (in response to dj_paige)Thanks for a fast response,
When I edit a typical JPEG image I only ever do the primary global corrections once (Levels / Contrast / Saturation) unless of course, I'm using Adjustment Layers. If I use the Camera RAW interface I would only use it once on an individual JPEG, but I have the benefit of returning to specific sliders more than once before opening the image in Photoshop.
It is my understanding that adjustments like Levels should only ever be performed once in a workflow if undertaken globally over the entire image - particularly if it's a JPEG.
Agree or disagree?

dj_paige Mar 24, 2010 12:57 PM (in response to Deep Woods)I can see if you make major changes to a photo using Levels or Contrast or Saturation, and then you try to make additional major changes, or undo the changes by again using Levels or Contrast or Saturation (instead of using Undo), this could cause a quality loss.
But if you only make minor changes using Levels (or Contrast or Saturation), and then a second round of minor changes, I don't see a problem. I can't imagine two consecutive minor changes is a problem.

I agree with you that raw interface is a consolidated place for all these tools. The major advantage is the non destructive editing which i too discovered pretty late. I too use it often now when i have to make only hue/saturation/exposure etc changes without detailed editing.

5. Re: Editing JPEGs with the RAW interface
Deep Woods Mar 31, 2010 1:00 PM (in response to dj_paige)Does two minor changes not equal one major change? I'm not sure. This also begs the question... at what point in using Levels, contrast or saturation tools does editing change from minor to major? Maybe I'm splitting hairs, but I don't believe everyone out there would agree at what point this is defined.
Experience has taught me that excessive use of Levels, contrast and saturation tools is a result of the image not being properly exposed in the first place, resulting in only moderate improvements. Many publications I came across over the years indicate single adjustments only when using these tools on JPEGs, unless of course one is using Adjustment Layers. This is why I was hoping for lots of feedback like yours on the issue of using the RAW interface to edit JPEGs. I've received very little feedback on this issue which tells me it is a little known option to users of Photoshop. It is so much easier to edit a JPEG using the RAW interface, rather than go through the conventional workflow with the other tools in Photoshop. So far no one has given me reason to think otherwise.
Your feedback is greatly appreciated.

Deep Woods Mar 31, 2010 1:05 PM (in response to ~V)I have not received much feedback on this matter, thank you for sharing your experiences. It is so much faster using the RAW interface I no longer see any benefit in following the more common workflow with Levels, Contrast and saturation tools unless of course I need to do more detailed editing.

True, major and minor is subjective, but I can see how you adjust the black point in levels, and then you come back into the photo later and decide to slide it a little more, I don't have any particular qualms about doing this, and I don't think anyone can look at the resulting image and say -- see, right there, quality degradation because you used levels twice.
The place where levels is most dangerous is when you either do ridiculous things, like move the sliders almost all the way to the middle, and then move them back almost all the way to the edges; or when you are getting posterization (which can happen from even a single use of levels).
Many publications I came across over the years indicate single adjustments only when using these tools on JPEGs, unless of course one is using Adjustment Layers.
Never read that. Can you please provide a reference?

Yes, I agree editing JPGs in the raw interface has a number of advantages, ease of use being one of them. Non-destructive editing is another advantage. My guess as to why so few people use this tool is that: 1) PSE is a very overwhelming program, and once you learn the traditional way to do things (which is what you get from most books and tutorials), you don't want to bother learning another way to edit your photos; and 2) RAW scares many people.
