Lightroom :: Previews Are Not Properly Converted To SRGB For Display
Dec 13, 2011
After updating to LR 3.6, DNG Profile Editor does not display previews correctly, if base profile is one of the "new technology" camera specific profiles (for example the v4 profiles for Nikon). It looks like the previews are not properly converted to sRGB for display.
I also noticed that if I decompile and then compile such a profile using dcptool of Chromasoft, the resulting profile generates very strange looking pictures.

I just switched from a PC (XP) to an iMac (Lion), and have gotten all of the pictures and catalog moved over. HOwever, none of the previews show. When I go to develop mode, picture opens, preview generated: But, when I then switch to another file, the preview seems to disappear and has to be regenerated each time.

So, after many trials and studying websites that take images seriously on different monitors I'm considering giving up trying to get converted sRGB images from my wide gamut monitor to look good in my browser. Sure if you convert to sRGB, in a wide gamut setup, the image will look good on old monitors.
BUT it won't look good on the new ones. Nobody talks about that. It really seems that some of the high end coporate sites are already converting to adobeRGB and putting images on the web that are converted to AdobeRGB and not sRGB. The photos look great in my browser on my wide gamut monitor and those sites' photos seem washed out on the sRGB monitors I used on the same sites.
There is no way for me to know for sure sinced the images are untagged but when I download them and apply the AdobeRGB profile to them, it looks just like in the browser. The sRGB profile washes out the image. Look at [URL] ....

We just upgraded to Revit 2014. We had several Revit 2013 models we converted. We are now experience some visual issues within Revit. Specifically, on our Exterior Elevation views, though we are using Hiden Line display, we are seeing some "wireframe" lines, like the double line where the roof is cut, we are seeing our floor betwen levels, etc. I was wondering if it was a Service Pack issue. Issue 1 has been released. I tried to install the patch, and received an error that the product is not installed. I have also downloaded the latest certified video driver, but have not installed that till I tried to get the patch updated.

Are the previews of deleted images themselves automatically deleted from the previews folder?

I bought Corel Draw X5 sometime back and had no issues.Then two weeks ago I purchased the Corel Draw X6 upgrade to take advantage of the 64 Bit design and the Free Corel Web Designer add on.My system is an AMD Phenom 965 x4 with a Win 7 HP 64 Bit OS loaded... 8GB RamI did non uninstall CD X5, when I loaded the CD X6So the problem....In Connect when I open a folder with pic files (raster) the Viewpane icons display normally...when I open a folder with Clip Art (vector) files each file displays the same default thumbnail with filename text caption... In my previous CD X5 32 bit install the Connect app worked with out errors displaying a Clip Art vector preview. Now after installing X6 64 bit, Connect in both x5 32 & x6 64 does not display previews for the clip-art .

I use Canon 60D and normally shoot in mRAW. I am considering a move to DNG conversion so I did some test conversions and was amazed to find that, far from reducing the size of my mRAW files, it increased them by about 60%. I repeated the exercise with RAW files and found that this did reduce the size of the files by over 10%. In fact, i ended up with the crazy situation where the DNG files converted from mRAW were much bigger than those converted from RAW.
Below are some sample sizes based on Medium previews, Embed fast load data - YES, Embed original RAW file - NO, Compatibility Camera Raw 7.1 and later
Before : mRAW 17Mb mRAW 12Mb
After: DNG 28.5Mb DNG 21Mb
Before: RAW 23Mb RAW 22Mb
After: DNG 20Mb DNG 19Mb
If I went for Full Preview, the DNG sizes rose by about 2 Mb
why the mRAW conversion is so inefficient?
I am still not entirely sure whether to adopt DNG but, if i do, it looks like I certainly won't be using mRAW as the source.

I want to calibrate my display properly and I am little confused. There are too many settings and wizards. First of all there are display settings (brightness, contrast, black level, color temperature, sharpness). Second -- graphics card settings (hue, saturation, brightness, contrast, color temperature, color correction curves). Third -- there are Windows color management settings in Control Panel (ICC profiles, WCS profiles, etc). Fourth -- Adobe Gamma. Firth -- I can use calorimeter to set display LUT.
How all that level of settings are related? In what order they should be changed? What color temperature is "best"? How Adobe gamma correlated with Windows 7 color management wizard? What is best? (They are producing different profiles.)
I "just" want to make photos of what I see, see it then on display more or less precisely and then print it.

I've recently installed Photoshop CS5 extended on my new comp It was working fine, but when following a tutorial to make rust or metal it starts having issues.
As you can see below the noise in the left hand picture worksfine, but in the right when applying motion blue I get a fuzzy line down the middle, and occasional a sort of beveled effect around the image.If I drop the motion blur to a low count it's ok, it's when I start upping the amount.
When I first loaded up photoshop it did say it had an issue with my monitor settup which I have recently sorted but the problem still remains.
My computer specs are below.
Operating System: Windows 7 Home Premium 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.111118-2330)

BIOS: Ver: CHG_712.rom vCHG7.12
Processor: Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz (8 CPUs), ~3.4GHz

I have and array that looks fine in model space but when viewed in a viewport from paperspace, sections of the array look like they are wiped out. Going back to model space everything looks fine. The only way I can get it to fill in is to delete the viewport and create another one. It's then fine for awhile but before long, areas are missing again. I've redone the viewport three times and it's starting to drive me nuts.

how can you work in adobe RGB and sRGB colours paces in LR 5. Why do my photos in prophoto colour space print so badly on my inkjet computer. If I am using the book module in LR 5 will Blurb be able to print them using prophoto colour spaces.

I have a Eizo ColorEdge monitor that is calabrated with a Spyder3 puck using Eizo's software. I shoot with a Sony A99 and A700 in RAW and use Lightroom 4.4. After editing I export using sRGB JPEGS. My pictures always look overly saturated orange.

I have AdobeRGB PSDs and camera RAW files, that I develop in LR and then export for web. Does LR default to a conversion to sRGB? I can't find a tick-box for this. All web images seem to get tagged sRGB, but I'm not sure whether this is a genuine colour space conversion, or merely a re-tagging.

LR works with the color space ProPhotoRGB. With highly saturated colors this colorspace is larger than AdobeRGB and sRGB. As I see it now is that while exporting to these color spaces, Lightroom uses the method as in Photoshop called Convert to Profile, which maintains the color appearance, but shifts the color numbers. High saturated colors will be clipped. Is this assumption correct? Is it possible to use in Lightroom the method Assign Profile, where the color numbers (and detail) are maintained?

With LR4 and a Nikon D7000.When i import that raw in lightroom, the first view of the picture is fine then LR do its "loading" and bang, the picture changes.As RAW is not supposed to be affected by the colorspace My understanding is the embeded preview in the raw is sRGB and LR work in a different colorspace. If i change the camera for AdobeRGB, i dont have the problem and what i see from the camera to the preview then the final result is consistent.But this cause me another problem because i shoot RAW+jpeg, the backup JPEG saved in the other memory card is now AdobeRGB as well and less compatible as everybody knows, for web, print labatory, etc...
I dont have in LR any automatic developement settings.My screen is calibrated with a Spyder 3.
I'm feeling stuck in the corner as i want by backup JPEG in sRGB and n o colorshift in LR.

I have a set of JPEGs that have been stripped of their color profiles (AdobeRGB). Lightroom assumes that they are sRGB images and displays them incorrectly. Is there any function in the program that will let me embed the correct (AdobeRGB) profile to the photos, preferably without re-compressing them?

I uploaded the Camera Raw update for a new Nikon P7100 to Lightroom 3 on Mac 10,7,4, but when the pics come up they're extremely noisy. When converted from RAW to jpg the noise remains.
No problem with JPGs. Same pics from the camera in RAW are fine on the Nikon viewer, so it seems to be a Lightroom mismatch.

When I am going through RAW files from my Canon cameras (1Ds MkIII and 6D) I edit them in the develop module and then convert to aRGB or sRGB depending on the output media. They look good in aRGB and sRGB too when I take into account the limitations of sRGB.
---> However, if I try the softproof to aRGB or sRGB the resulting proof crushes dark tones into solid black. Why is this when the actual conversions are way better? The actual conversions look good in both LR and PS CS5.
I have also noticed that when I upload images to my online galleries and view them with Firefox (latest version and color management enabled for all rendered graphics) they appear darker in the darkest tones than what they appear in LR. What gives?

I have a big concern. How can all my develop presets (more than 300 now!) be converted correctly so that the changes that one of them applied to one pic in the 2010 PV are the _same_ changes the same preset applies in the 2012 PV?
I'm not talking of Adobe LR presets (those that are installed by default and that come along with the LR itself) ... I'm quite sure Adobe has made a good job keeping them coherent with those of LR 3.x . I'm talking about of the huge numbers of largely available (on the net) presets .
I'd like to know if they will be converted _CORRECTLY_ with the 2012 PV so that they will work applying the _SAME_ _VISUAL_ changes as they did in LR 3.x .
Of course I'm available to manually edit the old presets, if necessary but how? Logically, there would not need to be a new process version if all they did was put a new UI on the same controls the old process version contained. The new controls set values for new algorithms (fill light apparently the most obvious) that don't work like the old algorithms, and can't produce the same results, but I'm pretty sure that the same visual results are still reachable somehow!
And I still need the old presets working as usually they did as a steady coherent base for my retouch workflow...

I have just installed Lightroom 3 - on PC laptop - and imported some images from the Picture Folder on the OS drive.Everything seems to be fine except (and its a major except) there are absolutely no thumbnails or previews of these pictures appearing in Lightroom to work on. I have tried this with a few different file formats.

In LR 4, you should skip the previews and just start playing a slideshow (it would render as it played). It looks like that's been removed in LR5? How can I restore the LR4 functionality?
