        Uh...so the question stands, have you indeed actually sent any example images where PV 2012 is less good than PV 2010 to Eric (and consider your what you say before answering cause I already know the answer).

         

        As far as I know, you've not actually sent any example images to Eric...correct?

         

        Eric has been very responsive to people who send example images...those people who do not contribute any examples tend to not get any response...and sending PM's don't count as example images.

         

        If you have any examples, show them (even if only to the engineers), otherwise it would be useful to learn how to use the exisiting controls (and maybe quit the harping).

         

        Just saying...

            I appreciate your participation and am sure you may have valid concerns.

             

            However, I have to call a "foul" for "piling on".

             

            The need for speed of processing and relative presets, valid or not, have not been a part of this thread.  If need be, start a separate thread here or in the requirements forum.

                    You've got to be kidding. Put the flag back in your pocket.

                     

                    Read through the thread and let's talk about who's piling on who. Rob has been taking all kinds of abuse for trying to work through the development issues in his own way. Adobe may well be following the substance of these threads but they're not doing a particularly good job monitoring the tone. Far too much hostility and abrasiveness from a small group of contributors who've forgotten they're just like the rest of us. Victoria sets a good example others should follow.

                     

                    For the record I'm quite capable of deciding for myself what's relevant, and I'm sure Hamish is too. thanks.

                      Let's see. Eric Chan and others have requested evidence form Rob in the form of files and they haven't appeared. We are all busy people who try and help the staff at Adobe to improve Lightroom for us the users. To wade through endless chatter about this and that with nothing concrtete to back it up and especially by someone who has blatantly promoted his own plugins that go against what has been recommended as best practise by Adobe, well is it little wonder that at times people get rather direct in their comments.

                      By the way none of the Community Professionals get paid by Adobe, we do what we do because we really enjoy helping the team to make all our lives easier through product improvement.

                        M, thank you.  We all try!  I've learned to turn the computer off when this forum is driving me mad...  

                         

                        As far as Adobe monitoring the tone goes, these are user-to-user forums, and moderation is very limited.  I'm sure it's a tough line to draw, between keeping a friendly atmosphere and being accused of limiting free speech or covering things up.

                         

                        Geoff makes a very good point.  It's great to be able to talk and work through the development issues, but we're talking about a very visual subject, so without photos, it's of limited value.  In fact, almost the opposite - if the engineering team are having to wade through chatter and figure out what people are trying to say, when they could just look at a picture and see immediately, it's taking away time that they could be spending actually improving the product.

                         

                        I'll be honest, when threads get this long, without pictures to back up the statements, I'm far more inclined to skim or even skip them.  I doubt I'm the only one.

                              Victoria, nice try to convince Rob to come up with image examples to show his points. However, I am convinced he would not do so. It is not really understandable that he has not even one image, which would be suitable to post here, and which can support his case.

                                    You SHOULD be able to use the white slider as a final adjustment.

                                    Are you sure?

                                     

                                    Admittedly, I haven't spend a lot of time with LR4 beta yet (I may stick to LR3 depending on whether or not LR 4 final will add better retouching support) but when I played with the "Whites" slider it appeared to stretch the whole histogram. I don't think that behaviour is a bug but intended.

                                     

                                    Is it the case that one can look at "Blacks" and "Whites" as moving the end points in a "Levels" tool, while "Exposure" moves them both in tandem (roughly)?

                                     

                                    I really wish there were a published explanation as to what the sliders are meant to do. This explanation can optionally appeal to intuition, but AFAIC, there should be one that also explains the effects in terms of low-level image manipulation terms. This would not only help to use the sliders as intended, but also to understand which "Basic control" sliders can be augmented/counteracted/complemented by tone curve controls.

                                      The tone curve controls follow the Basic panel controls (in our processing pipeline).  Hence they are fully complementary to the Basic panel, and are intended to be used (if at all) after the Basic panel has been optimized. 

                                       

                                      Whites and Blacks are meant to determine how much of the image is mapped to pure white or pure black, without changing overall tonal relationships.  Similar to Levels in Ps, this means the entire histogram must be affected.  Unlike Levels in Ps, the implementation in Lr 4 Beta is more sophisticated in that it concentrates the effect more at the respective endpoints, again in an effort to preserve tonal relationships.  Furthermore, the implementation in Lr 4 Beta has some "image smarts" to make sure the sliders always have enough range & precision to map a significant portion of the image to pure white/black (if so desired), regardless of how much contrast the image had to begin with.  This is particularly effective for low-contrast images.

                                        Yes, in concept but it's a lot more complicated...The Exposure in PV 2012 is like a smart brightness slider that doesn't really behave at all like the middle slider in PS levels. Plus Exposure in PV 2012 has a rolled off clipping in plus settings and a degree of he old highlight recover in minus settings. Blacks and Whites are really designed as gentle tweaks on really like the end point of levels.

                                         

                                        If you look at an image and evaluate what it needs, most of the time the heavy lifting is done with Exposure and Contrast–and if you don't use Contrast in PV 2012 then you're gonna have problems.

                                         

                                        Highlights and Shadows are further adjustments above or below the middle range where Exposure is the most aggressive. Whites and Blacks are really a fine tuning of the previous slider adjustments. If you have the Exposure and Contrast sliders set optimally, you prolly shouldn't be needing to make major moves with Highlights, Shadows or Blacks and Whites.

                                         

                                        And all of this is fundimentally different than PV 2003/2010. So, what you think you know needs to get adapted to the new controls. And that takes time and experience...but the results, not withstanding the title of this thread, are superior...

                                         

                                        LR 4.0 won't have much added from the public beta...some things may change in an update. Historically, the first dot release has actually gotten some new features primarily because Camera Raw gets locked in so early in the CS development. Thomas Knoll has been able to add things after the CS main release as long as it happens by the end of the quarter in which Photoshop ships. Anything Camera Raw gets in terms of features, LR also gets...so, who knows, maybe LR 4.1 will get some new stuff in it.

                                            Yes, but as the effects of the basic controls and the tone curve overlap, there is more than one way to skin a cat, so to speak, and my question was geared towards how to best distribute the image manipulation work between basic control and tone curve and whether or not some kind of adjustments were equivalent.

                                             

                                            For instance, changing the extreme end points in the tone curve is equivalent to moving the black and white sliders in a "Levels" tool. From what you are saying, I gather none of the basic control sliders can be mapped (at least roughly) to simple operations on the tone curve. I also believe this partly to do image masks being used rather than just being limited to shift contrast (as the tone curve basically forces one to do). However, the masks seem to

                                            use rather soft gradients, otherwise it wouldn't be necessary to affect the whole histogram if one wanted to just boost the whites, for example.

                                              I have never used "Contrast" in LR3 for the following reason:

                                               

                                              The working point for contrast will usually not be optimal for any particular image I'm working on.

                                              I hence achieved the affect of a contrast boost by manipulating the tone curve. By doing that, I have a choice where the steep (vertical) part of the "S" curve is. When I use contrast, the steep part of the equivalent "S" curve is always in the middle, correct? I don't think that is optimal.

                                              If the contrast slider had a sub-slider which I could use to set the working point, I'd probably use it but then the tone curve seems to offer even more flexibility with no disadvantages.

                                               

                                              For the reason mentioned above (fixed working point) I would be uncomfortable to touch "Contrast" in LR4.

                                               

                                              Is some my thinking wrong?

                                                Well, for PV 2012, yes I think you are wrong...Exposure and Contrast are now image adaptive which means that the image source has an impact on how the adjustments work on the image. Not using any contrast adjustment is leaving a lot of lifting to the curves–which as Eric indicated happens in the pipeline AFTER all the Basic panel adjustments touch the image.

                                                 

                                                I would suggest using Exposure for the main tone control followed by Contrast to adjust the base level tone curve followed by Highlights to tweak above mid tone and Shadows for below mid tone. Whites and Blacks are the last leg to set clip. Highlights is also where the largest highlight recover comes in (although Exposure and Whites has some I "think"). Shadows has the same sort of functionality Fill Light had but it's been optimized to really reduce the halos Fill Light had.

                                                 

                                                I've pretty much gotten away from using Parametric Curves now with PV 2012 and only bounce into the Point Curve for editing extreme highlight detail to tease more specific textural detail that Highlights and Whites can't really adjust. Plus, now we have Red, Green and Blue curves to adjust color casts. In many respects, the new Basic panel is almost like Parametric Curves on image adaptive steroids with highlight recovery and fill light thrown in...

                                                      I love it. This is exactly how it should have always been. Nobody should have to worry about blown highlights or clipped shadows. This is precisely what software was made for. Maybe they could add checkboxes to unclamp highlights and shadows for people who like blown or crushed looks, but personally, I doubt I'd ever unclamp.

                                                        Mark, thanks for your feedback.  This is actually what we did with the +Whites direction.  As you push Whites to the right, it will "straighten out" the highlight shoulder to provide the digital "hard clip" and once you go past that point, it will continue to hard-clip more and more.  So, as you say, photographers who deliberately want blown/crushed highlights (e.g., for effect) have a means to get them, without going into curves.

                                                         

                                                        Rob, I disagree.  Our feedback so far from photographers is that they are using curves less now, not more.  (If overall people are using curves more in 2012, then we've failed ...)

                                                          TK, when "boosting whites" it's a judgment call as to exactly which tones get "boosted."  For example, if you leave the shadows & midtones exactly where they are, and only raise the light tones closer to pure white, then there's a side effect: increased midtone-highlight contrast.  In terms of curves, that's like increasing the slope of the upper part of the curve ("stretching out" those tones), and that's what I mean by changing tonal relationships. 

                                                           

                                                          That's a side effect we didn't want, because the point of the first 4 controls (Exposure thru Shadows) was for the photographer to first establish the primary tonal relationships (overall brightness, and balance of highlights to midtones to shadows).  Once those are established, we didn't want Whites/Blacks to mess up that balance.  That's why these controls affect the whole tonal range (rather than a limited tonal range, like Highlights/Shadows).  Their purpose is to set the desired white/black endpoints, but their implementation involves moving the whole tonal range as needed to satisfy the desired constraints.

                                                            Although I've yet to be able to accomplish exactly the same effect with the whites slider as of a virginal handling, I'm still working on it, and truth betold, part of the deal is in the gradation leading up to the end-point, which is greatly affected by the exposure/highlights combo (and contrast of course) as well as +whites. Anyway, no worries really - this thread caused way more trouble than it was worth...

                                                             

                                                            I personally use curves more with PV2012, but perhaps I'm the odd man out, and perhaps that will change.

Get the whites done along with exposure before finalizing the rest of the toning, or at least that's what I'm trying to do at the moment.

I mean, I often use +whites in conjunction with reduced exposure, just to stretch out the top part of the histogram more. Know what I mean?

                                                                  - Exposure: -3.0 (and I don't mean -.30, and this photo was NOT overexposed).

                                                                  - Contrast -10

                                                                  - Blacks -24

                                                                  The overal tonality of this photo is about the same as before, but radically different look & feel due to the whites being used as an "exposure subsitute". The same principle applies when one is after less extreme effects - if you just want to expand the top end a little, then increase whites a little and decrease exposure a little. If you just want to compress the top end a little, then decrease whites a little, and increase exposure a little.

The only way to confine the tool to the upper most tones so that it has the intended effect, is to use it in conjunction with exposure. There will still be an effect on the rest of the tones, but it will be much less.

I would think that the issue might not be quite as obvious in a small websized jpg, but I also don't want to just post full resolution images...

In the mean time some screenshots (compare the same image in PV 2010 at default to PV2012 at default as well as what happen when you lower whites in PV2012) would be nice. I think I know what you are talking about but would be nice to see it.

When I try to correct for it, it has a negative effect on my actual subject; in some images it negatively affects the subject from the start.

                                                                                     

                                                                                    I will email Eric Chan as suggested so that he can see my particular issue, and hopefully help out.

                                                                                     

                                                                                    Whether metering "in studio" with a light meter or the cameras meter, you still need to "calibrate" to what you can expect in the RAW image....as processed by the raw converter.

                                                                                     

                                                                                    If you are comparing 2010 with 2012 in your statement of "...the "auto recovery" seems to be pulling back a stop or more of the whites/highlites...", this is only because 2010 would show revoreable highlights as blown, when this were not.  You can easily "blow" them back up with exposure, highlights, and/or whites, if you want.

                                                                                     

                                                                                    I am not saying you do not have a problem.  However, my experience is that you easily have 1+ stops of headroom in RAW, above what you would expect from the histogram.  Suggest you paruse Varis's article....if I am wrong, I apologize for my intrusion.
