Lightroom vs. ACR slider response

I have been having this issue ever since installing Lightroom last year but have been living with it. When I move any of the adjustment sliders to correct an image, the image seems to flicker or alias slightly while the slider is in motion then stops when I stop moving the slider. It isn't so bad that I can't work on my pictures but I never have this happen when using CS3's ACR. With CS3 the movement of the slider produces a nice smooth transition as I adjust it. Does anyone else have experience with this or know what might be happening? It does get annoying after a while, if I'm working on a lot of images, and I find I end up going over to CS3 ACR to work on them. Any advice would be great. As an FYI I'm using a pretty high end machine with tons of RAM so I have ruled that out.

Maybe the proper question to ask here is: IF it is supposed to be a performance enhancer...HOW is it supposed to work to enhance performance? 'cause nobody with a system that is attainable to mere mortals* sees a performance enhancement from it!
* When I say this I mean a system with 2-4 cores and 2-4 gig of ram. This is all now "some what" affordable. So please don't tell me that it enhances performance on a 3ghz octo-core with 12 gig of ram. This systems specs are unreasonable. ( I also understand the 8 cores and gobbs of ram Will be More affordable in about 1.5-2 years- but not now)

Capture vs. Content Sharpening in Lightroom and ACR

Hi,
I have a question regarding sharpening in Lightroom and ACR. In the information I have read, many authors point out that Lightroom and ACR's detail panel is optimized to provide control over capture sharpening. In a post that I read recently by Jeff Schewe, he clarified that and said that we are really sharpening for both capture and content with the detail panel in Lightroom.
That is confusing to me because after reading Bruce Fraser's book on sharpening, capture and content sharpening were treated as two different processes. If I understood correctly capture sharpening for digital captures was based on the characteristics of the camera and the file size of the image, with larger megapixel files receiving a smaller radius. In addition, I read that the radius in content sharpening is dictated by the dominant characteristics of the subject matter being sharpened, with high frequency subject matter receiving a smaller radius and low frequency receiving a higher radius.
The reason I am confused is that it appears that capture and content sharpening for the same digital capture can at times be quite different. For example, I believe that the book suggests a radius for an 11 megapixel capture of .4. If the image content calls for a sharpening radius of 1.3, what do I do? In Lightroom/ACR I can only choose 1 radius.
In all the reading I have done regarding the proper use of Lightroom and ACR, it suggest that you should use a radius that is suited to the image content. So it appears that we are that we are being encouraged to perform content sharpening only with Lightroom and ACR. What happened to the "capture" sharpening portion of the process?
Since Lightroom and ACR are capable of recognizing the camera make and model as well as the file size, are they applying capture sharpening behind the scenes that is tailored to that specific camera and file. If not, then how are we achieving both capture and content sharpening in the same operation?
Sharpening for both capture and content in one pass would seem to conflict with some of the basic concepts elaborated on in Bruce Fraser's book. I am assuming that since Lightroom is using Photokit Sharpener routines, that they have accounted for the capture portion of the sharpening, but I don't see that stated explicitly anywhere in anything that I have read. If they have, I say kudos to everyone involved as that would be great. I'm just looking for a clearer understanding of what's happening.
If anyone can shed some light on this topic I would be very appreciative.
Thanks,
John Arnold

The answer is that the detail section crosses over into creative territory and is not strictly "capture sharpening," although that is what is mostly meant to do.
Following the ultimate logic of the "sharpening workflow" might make you conclude that Capture sharpening and output sharpening are purely scientific steps where you should not make ANY creative decision at all and that creative decisions are only to be made in the creative sharpening step. In the real world, there are creative decisions and decisions determined by the content matter that enter into the capture step too just like in the output step. You might like extra-crunchy prints for example, but somebody else might prefer softer prints making you approach the output sharpening with a creative intent. The sharpening workflow was probably (Jeff will know more about the history) more of an attempt to arrive at a more rational way of approaching the process and to provide a guideline. It is probably not meant to rigidly separate the workflow up in defined steps where in the 1st step you're not allowed to think or look at the image, in the second step you can go completely wild, and in the last step you have to close your eyes again. The goal was probably to make the photographer realize that the different steps have a different purpose. Not to make you turn off your creative genius or to treat the process like a black box.
My approach to this, inspired in some part by Jeff's many posts on this, is to make the image look good at 1:1 using the detail tool in Lightroom/ACR. This is inherently driven by content of course as you use visual feedback. If your image is large swaths of plain color separated by sharp transitions with little structure, you probably do not want a high setting on the detail slider as you might induce halos and you probably want to use some masking. Conversely, if you shoot brick architecture, a high detail value might look good. If you shot at high ISO, you might need a different approach again to not blow up noise. Also, portraits might need a different approach. After the 1:1 optimization, I sometimes selectively sharpen (or blur!) parts of the image (rare but can be effective - example would be people's eyes). Then for the output step I use appropriate output sharpening for the medium according to my taste. You see that this is not rigidly following the workflow, but still is in the spirit.

Cropping in Lightroom and ACR+edit in Photoshop

Using the latest versions of Photoshop CC and Lightroom. After editing a raw file, including cropping, in either Lightroom or ACR and then
proceeding to Photoshop, the adjustments-exposure, white balance etc. are imported but not the crop! Very strange. Help would be appreciated in
solving this problem. Thanks in advance.

Thanks for the quick reply Graeme. That is correct. I have tested the issue with a representative from NIK/Google. The "selective tool" was causing the problem. I was dealing with other problems too, like the "exposure" slider in ACR was jumping back all the time. I have been following another discussion concerning this (http://forums.adobe.com/message/5806682#5806682). I have not tried it yet, but there they have had success tackling the problem by changing the Country/Region.

How to use snapshots from Lightroom in ACR?

Applying some changes to an image in LR and then saving it to DNG or a XMP sidecar file will make that changes the defaults when importing a RAW in ACR.
But I wasn't able to make settings saved in those files in form of snapshots selectable and usable in ACR.
Am I looking at the wrong places or isn't it possible (for now)? I'm using ACR 4.2 in PS CS3.
Johannes

Lightroom already writes and stores snapshots in a LR written DNG but only Lightroom can use them.

Lightroom 5.7 slide show crashing

I just moved Lightroom 5.7 to an I mac retina. Overtime I try to use the slide show module, it preps the slide show, then crashes once it begins the show. It was working well on my old iMac 27 in. Any suggestions? Running latest Yosemite operating system and 32 gigs RAM. Also noticed the slow processing speed in develop mode which I saw reported in other posts.
Thanks

Lightroom 3.6 Slide Show auto-advance

I just got a new computer and use Lightroom 3.6. Now when I make a slide show and save it as a PDF it won't auto-advance to the next slide when running. When I review it in Lightroom it auto-advances fine but when I run the PDF file it sticks on the first slide and must be advanced manually. I believe I'm running the latest version of Adobe Reader as I just downloaded it last week when I got my new computer. Can someone explain how to get the auto-advance feature running like it did on my old computer? Thanks.

I don't use the slideshow module very often. But I just quickly created a small slideshow. In my little test the images did not auto-advance until I went into full-screen mode. Then it worked just fine. Also, make sure you haven't checked "Manual Slideshow" in your options.

Camera Profiles Missing from Lightroom and ACR since upgrade to Lightroom CC

I upgraded to the latest version of Lightroom yesterday. I have discovered since then that the only profile available in the Camera Calibration profiles pop-up menu is Adobe Standard. This applies to Lightroom CC, Lightroom 5 and ACR. Furthermore the folder where the profles were stored is missing. This is a problem as I have lost a custom profile for editing the white balance in infrared photographs. What is the likelycause of this situation and how can it be remedied?

Hi Beat,
thank you very much for your reply! :-)
That is what I find so puzzling - there are hundreds of profiles in that folder under a "1.0" subfolder...
And yes, I'm sure it's RAW I'm looking at (and the error message appears before I see Lightroom, so it's not about RAW/JPG).
While fiddling some more I found out, that if I start Lightroom as an Administrator, everything is back to normal, but I never had to do this before and I don't see why this should be the case. What would cause such a behaviour to appear suddenly?
Rant:
The whole UAC idea - as Microsoft implemented it - is a major pain, but so far I was willing to bear the burden for the supposed raised security, but more and more I tend to think about switching it off as I did under Windows Vista. If it interferes with my ability to get anything useful done it's not worth it (and I have other software that doesn't like it, not just - suddenly - Lightroom).
Thanks for any hints what this problem could be about!
Cheers,
Thomas Helzle

Lightroom and ACR - Keeping all files together

Not sure I'm asking the right questions but I'll give it my best shot.
According to what I've read, it appers that the only way to get a job into Lightroom is to choose Import. What if I have a job folder with RAW files that have already been manipulated in ACR? Is there a way to simply point Lightroom to that folder without having to import into LR and have all the files be copied again?
Also, if I open the RAW files in LIghtroom after working on them in ACR, will LR cause the RAW files to first go back to their defaults? If so, is there a way to get them back in ACR as originally worked on?

Ian,
It's so nice to see you. I was thinking about you recently and wondering how your were doing.
Thank you for your help on this. I must have overlooked the drop down menu.
I am relieved to discover that even though LR copied and converted the files to DNG, it didn't seem to affect my previous work. Also come to find out it created a new folder for the DNG within the other folder.
Thank you again!
Linda

Lightroom to ACR???

Can any tell me please if it is possible to open an img
ae from lightroom 2.5 directly into ACR.
Thanks for your time
Stewart.......

ACR is a plugin for Photoshop and you would need PS CS4 with ACR 5.5 for that to be achieved.
Lightroom 2.5 has the same raw processing and functionality as ACR 5.5 so you can achieve the same by using the develop module in LR.

Lightroom 3.6 slide module crashes - XP SP3

Lightroom 3.6
Windows XP 32-bit SP3
Dell Dimension 4600
Intel Pentium 4 2.8 GHz
3.0 Ghz RAM (4 G installed - XP only uses 3)
2 350 GB Western Digital Hard Drive
C drive for system and programs
D drive for data
External 500 GB G-Tech drive for Lightroom catalog and photos(USB 2.0)
64 MB Nvidia Quadra NVS with AGP8x. (I usually run 2 monitors. I changed display settings to one display with no difference in results.)
I selected 19 starred photos in the library module. (Jpeg's approx 2.5 MB each). When I try to preview in the slide show module or go to Window-->Impromptu Slide Show, the screen immediately goes to black and the computer restarts. No error messages.
Thanks for any help you can offer!

Have you updated your graphics card driver direct from nvidia? Graphics card issues are usually the cause of slideshow playback issues, although for the computer to actually restart itself sounds like there may be a hardware issue. Is your power supply beefy enough? Could something be overheating perhaps?

Lightroom 2 slider adjustment

In Lightroom 2.0 (Windows XP) I was able to click on a slider and move it gradually (left and right) by rotating the mouse wheel. Updating to Lightroom 2.2 that feature no longer works. Do I need to change a setting or has that feature disappeared?

Pardon a small rant here about what I find to be LR's abominably imprecise and erratic slider response. This is not in reference to using the mouse wheel, but to the plain ol' mouse movement (click 'n drag) method:
Balky and erratic response from LR sliders is, for me, a source of much frustration and irritation. For example, if I need an "odd-numbered" adjustment value: well sorry, at the moment we only seem to be getting even numbers via the slider--although getting back to "zero" quite often is not achievable by dragging the slider (no matter how minute the movement). So I keep trying and then suddenly (hurray) there come along some of those pesky odd-numbered values, but alas certain ones "of the even persuasion" now become inaccessible via the same slider! Still no zero. Yikes. Sure, I can always get any particular value I want (e.g., with keyboard entries and/or double clicks, etc.)), but those are extra steps and also often result in a cluttered history panel. LR is supposed to make the workflow _more_ efficient, right?
The erratic LR slider response was made all the more obvious to me the other day after I made one of my infrequent side-trips into Photoshop CS3 for some editing. Of course I needed to use some sliders, but in contrast to what I'd become accustomed to in LR, the PS slider response was soooo smooooth and precise and predictable. Any value I needed (even zero) came along with no fuss, and no muss. So, what's up with the LR slider behavior? BTW, I've been a LR devoteé since the very early betas (now using 2.3) and all the while waiting/hoping in vain for certain interface refinements.
I wonder why Adobe cannot get a simple tool work as smoothly in LR as it does in PS (and don't get me started about LR's cropping tool!)? Yes, I guess I can rationalize about how PS is decades-old while LR is still in its infancy, but I've grown tired of that all-to-familiar refrain.
Maybe my slider issues are due to using an elderly PowerMac G4 (OS X 10.4.11) with an admittedly limiting 2Gb of RAM, or the fault of my Logitech wireless mouse? Are the slider behaviors I described not generally experienced by many others? ;-)

Can't open a raw file from Lightroom to Photoshops ACR

I got used to using Lightroom 3 as a place to catalogue and store my images but still process my Raw files in Adobe Photoshops Raw Convertor. Now that I have Lightroom 5 I can't find out how to do this. With version 3 I just highlighted say 3 files and hit command E.
I know I can open an image as a smart object and go about it that way but I can't open multiple images from Lightroom to ACR.
I know people will say '' hey well do your Raw work in Lightroom'' but I got used to using the Photoshop Raw convertor and I spent a lot of time and money learning it.
Surely there is a way to open say three images from L5 to ACR ???
Please help this has been driving me nuts, It's suggested I will need to start using Bridge but I'm bewildered and don't want to start learning something new.
Thanks in advance.

It has been a long time since I even had Lightroom 3 installed on my computer. I don't recall the behavior you are describing. ACR is used to translate the adjustments made in Lightroom as the image is transferred to Photoshop. You may have become accustomed to a certain behavior, but it doesn't work that way. The process of moving from Lightroom to Photoshop works on the assumption that you have done your raw adjustments using Lightroom, and you are now passing that image to Photoshop.

Lightroom doesn't recognize ACR 5.5 and my D300s RAW images

Lightroom 2.4 does not recognize my Nikon D300s RAW images. I downloaded ACR 5.5 and after install both Bridge and Photoshop CS4 handle the D300s RAW images but my Lightroom 2.4 will not import them saying that it is a damaged or unrecognized file type. I have rebooted my entire Vista system and the problem persists. Any suggestions on how I might make Lightroom recognize ACR 5.5 and my D300s RAW images? Thanks in advance.

You don't want Camera Raw 5.5 (unless you want to use Photoshop CS4), you want the DNG Converter 5.5 which can convert the D300 raws into DNGs that are compatible with Lightroom 2.4. The next version of Lightroom (presumable 2.5) will have the support built in without needing the DNG Conversion...

Lightroom (ACR 4) color management problems

Lightroom (or ACR 4) has some color management problems. When I develop a DNG into Photoshop (sRGB) everything looks great. Then I proof colors for the web (monitor RGB) the reds become oversaturated. I don't see this problem when I develop the same DNG using Bridge (ACR 3).
Any picture that I develop using LR that looks great in Photoshop, becomes way too red when published on the web.
Whats going on here?

I have confirmed this finding using Photoshop CS3 beta - same problem in converting to the web - too red!
