Lightroom :: HotPixels Show Up After Several LR Processing Steps
Aug 10, 2012
I am having two problems with Nikon Raw Processing and LR4.1.
1st: I am producing and processing content for ESO (European South Observatory), especially TimeLapses. Those sequences consist of hundreds of Images in hundreds of folders. Source files are either from D3s, D4, D700, D7000 or the like.
Several development changes are applied to single key images in a sequence, and those later applied to all images in that sequence. Problem is that after a certain amount of development changes (that are written in to the XMP sidecar files with LR4), hot pixels start to show up in the images that were not visible before.
Seems like the oversaturated pixel information (Hot Pixel) that is always stored within the RAW images, is lost after a certain amount of development changes.
2nd: is there a known trick how to force LR4 into updating ALL thumbnails after development changes, including those, that are outside the currently visible grid view?
It is very time consuming to manually page up and down the grid to have LR4 updating the thumbnails on each page (of for example a folder of 1200 images) so that one gets a preview of the TL sequence with the current development changes in Library View.
When one decides to edit a photograph what do people use as a rule of thumb to know what to do 1st.Assuming one will change contrast, do something to the color, enlarge a photo, use onOne software to create a frame, delete a wire etc.
I am an experienced user of Lightroom and get excellent results. But an anomaly is puzzling me. I capture images in DNG format and download to a PC Windows 7 using a calibrated Eizo graphics monitor. Before exporting and delivering a processed image I ensure that there is no unacceptable clipping showing on the histogram. I export 16 bit files which are only converted to 8 bits immediately prior to delivery. Recently I have adopted the procedure of importing a copy of the final delivery image back into LR4.3 for better library management. (There are often keyword changes or other refinements in the delivered image) Occasionally I notice that some pictures are noticeably brighter than the existing LR processed masters which formed the basis of the above operation. So I did some tests.
I selected an image with wide tonal range, adjusted it in Develop module to meet my 'no unacceptable clipping' rule and exported it as described above into CS4. My working colour space is Adobe RGB 1998 and Color Management is set to 'RGB Preserve Embedded Profiles'. In CS4 I only changed the mode from 16 to 8 bits and then saved the file using a modified name. That was the only processing done in CS4. Both files (8 bit and 16 bit) were then re-imported back into LR4 and the histograms compared with the original modified master file. In both cases they showed highlight clipping indicating that the image is brighter than when starting the final processing in CS4. In most cases the extra brightness is not a big problem; but in some instances it is quite unaccepable and I could not use that version without further processing in LR4. Mode change does not seem to be the culprit.
What I might be doing wrong to bring about these unwanted involuntary changes to normally processed files?
LR5 Win7. I open a previously edited image in Develop module. I click on the first step of the history ("import...."). Immediately, all the history steps disappear, and a new step appears, "Post-crop vignette style: paint overlay." There are now just two steps in my history. When I try to click on the first/origial step, LR doesn't let me do that, it immediately jumps to (highlights) the "post-crop..." step. If I go to the Effects panel, the only option under style is "paint overlay." If I add a few more edits (change color, etc.) they work fine. But as soon as I click on the first history step, the same thing happens again.
Update as i work on this: if I click on ANY previous step in the history, LR adds the "Post-crop..." step at the top and does not then let me click on any previous step.
This does not happen with photos I have edited recently. It only happens with previously edited photos. I think it only happens with photos with 2003 or 2010 process, but it doesn't happen with all of them.
Then I tried opening one of these photos in the Develop module. I create a virtual copy, then go back to the original. I click on the first history step in the original, it does this strange thing described above. If I add more history steps to the original, then click on the first step, it also does this strange thing. However, if I add edits to the virtual copy, then click on the first step, it does not do this strange thing.
What I have tried:
-I have opened and restarted LR. -I have gone back to a catalog from a few days previously and it exhibits the same behavior. -I have tried updating the process before clicking on the earlier step, and this does not prevent the behavior.
I wanted to try to re-install LR, but when I try to download it, I get this message, "We're sorry, something seems to be wrong on our end. Please try again later."
I have just editted an image, initially by cropping, then making some general tweaks. I saved this as a Snapshot.
After some though, I decided I wanted to change the crop, so I went back to the original image, and re-cropped it. Fine, But now I wanted to re-apply some of the changes made in the Snapshot. How can I see the steps that I went through to create the snapshot? I saw Update with Current Settings on the sub-menu (right click) for the snapshot, but wasn't sure if that was what i wanted to do.
I have been trying all week to find out if there is a way to embed editing information into a file upon exporting it from LR. Can you use metadata? What I mean, is, years down the road, I want to remember how I edited a particular photo... Is there anyway for me to do that so it's in the photo's properties?
I have just edited some photos for a friend who was short on time, and now she would like a list of the steps I took in editing. Is there any way of listing those steps in a text file I could send her?
I am considering purchasing Lightroom v.4.3. I will be shooting in RAW with a Canon 6D and Canon 7D camera. Is the support for working with RAW files and then converting them to jpg files built in to Lightroom v.4.3 or must one purchase a separate add-on module to perform those tasks?
This problem is specifically related to using LR & PS to process Infrared images.I am having problems processing Infrared Images when using LR & PS. I take my IR images with a 530 IR conversion to a Canon G12 camera. I learned early on Adobe products don't play well with IR images (they come in magenta when importing ) so I bring IR images shot withmy G12 into my computer with Canon Digital Photo Professional and then work in LR & PS from there.
If I then directly open this imported image from my hard drive into Photoshop and try and do adjustments such as blue sky adjustments with a red/blue channel swap, it works fine, just as I would expect.(If you are not familiar with IR processing, I understand this introduction and question will not make sense).But when using Lightroom, I sometimes have issues. I always import all my images into LR. Even with IR images, after using DPP to bring them to my computer, I import them into LR for cataloging purposes and to make other potential adjustments. Then my usual workflow is to move photos from LR to Photoshop via the "edit in" command. This opens a dialog box giving a choice of "edit a copy with LR adjustments" which is the default option and the one I always use, or "edit original".
Here's the interesting thing I finally discovered.If I send the photo from LR to PS using the "edit a copy with Lightroom adjustments" option, I get a bad blue sky effect, where the sky is green and the foliage is pink instead of the sky being blue and the foliage yellow. But if I send it to PS using the "edit original" option, the blue sky effect works fine.So there appears to be an issue when tring to send IR images from Lightroom to Photoshop.
When I shoot images with a high dynamic range I use the AEB function to create an HDR image in PS merge to HDR Pro and save them as 32bit tiff.
Is it best to then process these in LR5 or to use the Camera Raw dialogue or is there no differance in exposure,highlights, shadows, whites, blacks and contrast functions whilst processing 32bit images?
When using an external editor (PS CS5) to edit photos from Lightroom 3, there is an inital preference to select whether to use ACR in PS to process the raw file, or to use LR. I always want to do this in PS. There's often times where I'm compositing multiple photos. I only need to open up that raw file to quickly grab a section of it to move into another file. I don't want to save the raw file as a psd, tif or whatever, just select, copy and move that section of the file and then close it.
The problem is that preference setting is only when you first set up the Lightroom, I'm not seeing it anywhere on any of the preference menus. And for some reason, it has switched to processing the raw in Lightroom. So now i'm ending up with useless psd files. That takes up space on my hard drive, takes longer to archive on to external hard drives, and is slower to open the files into PS. It may seem like a small inconvenience, but when shooting 1000s, or 10000s of images a week it adds up quickly. And to get rid of them, i have to reveal in finder, then delete, then remove from catalog in LR - which just wastes time.

LR and PS are both great in their own right, and do things better than the other in some situations, I wish Adobe would make them play nicer together.
I have three (and a half-follow-on) questions on DNG nuances/technical particulars (that are prompted by remarks appearing on the last-updated-about-two-years-ago webpage URL...
First, what (If any) image processing capabilities (such as any further highlight recovery/adjustment, or individual color channel enhancement/ saturation improvement, etc.) are unavailable in Lightroom (LR) or Adobe Camera Raw (ACR) if one opens-with/inputs-or-imports-to LR (or ACR), a Linear DNG (linDNG) image file (which by its ‘linearized’ nature has already had certain image attributes ‘baked’ therein), and what image processing capabilities are fully available in LR/ACR for such a linDNG image in an unrestricted/fully-further-adjustable manner?
Second, is the output file produced by Adobe’s DNG converter when one inputs to it (say) a Nikon NEF raw-image file a (what I refer to as) Raw DNG (rawDNG, akin to those that some camera manufacturers’ cameras are now directly storing on memory cards at image capture), or a linDNG (akin to those produced by various RAW converters such as DxO Optics Pro and Capture One Pro)? If the former, is it possible to apply Adobe’s DNG converter to a linDNG input file (and thereby, effectively, ‘unbake’ whatever settings had earlier been ‘baked’ into that linDNG so that the resulting rawDNG would be once more ENTIRELY/UNRESTRICTEDLY further adjustable in LR/ACR?
Third, if one uses either LR or ACR to open/access/edit a linDNG image file, performs some non-destructive image adjustments on that image with that software platform, and saves the results as a new/differently-named DNG file, will that resulting new DNG file be yet another linDNG-format file, or a rawDNG-format file?
Can you enable the lens profile settings for more than one image at a time? If multiple images were imported and the same lens was used for all of them can you batch process them without having to do one image at a time?
I have been using LR since it has been released in version one. I have a very modest system, Win 7 64 bit Home premium, Processor 6.6 GHz; Memory 4GB; Displaty 1680x1050.Test on export of 101 raw files from Panasonic G3 Lightroom time for rendering 15 Min approx 9 seconds per file.Export from After Shot Pro Approx 3 Min 1.87 sec per file.Both systems using only standard processing functions no Lens corrections, adjustment brush etc. just standard corrections.Just unbeliavable. I did not think I have an issue with the performance of Lghtroom but this is a revelation. I have no hangups or crashes etc.
is it possible to drag and drop processing options (in German: Entwicklungseinstellungen) from one picture to another? The usual way by right clicking on the picture and then selecting copy the justifications and then right clicking on another picture and pasting them is very slow.
It would be fantastic if I could just use the spray tool to quickly transfer the options from one picture to a group of others. But this is only possible with presets I first have to save. But many processing options I don't want to save as a preset, because they are not that important. I just want to have a possibility to quickly play around with the options.
Is there a way to disable lightroom 4 from importing or processing any file with a video extension mkv, 3gpp etc, as its really slowing down my workflow.
My typically workflow consists of pulling my files off of my memory carsd manually via explorer (into a specific folder under a root folder which I create manually). I then synchronise the root folder in lightroom.
Unfortunately LR4 seems to take over and hour to do this since I have a lot of uncateloged videos. LR fails each time to catalog the videos.
LR3, since it didn't support video, was blazingly fast and performing the same operations in LR3 takes minutes as oppose to hours.
I need to know how to do the above procedure in lr5 as when i did the processing of one image i saw no tab to click to save the image or move the image or clicking done?
All of a sudden today when i went to process photos, in either Lightroom 4 or CS5 all the skin tones are bright pink? They are fine when viewing them on my computer, just not threw adobe products.
I'm trying cs4 TRIAL. And I get bad steps (look by the arrows) when LETTING GO of pen pressure. Normal?
NOTICE!! Both are drawn at 25%spacing which I want, because the pressure gets easier to control. http://tinyurl.com/6nlqop [img]http://tinyurl.com/6nlqop[/img]
I am new to creating actions, I have crated a design I am happy with and I want to recreate it easily with an action. The design uses multiple stages and filters, so its a real pain to retrace steps. Is there a quick way to create an action set without having to go through all steps again?
How can I determine the 'steps' in a workpath? I want to fade my brush along a workpath so that it perfectly decreases in size along the whole workpath to the end and so far i just guess as to how many 'steps' there are in the workpath and then keep adjusting. Surely there is a better way....
I've heard that when making a photograph smaller in Photoshop the results are better if it's done in steps instead of all at once.
If this is true how much should it be reduced each time and should the change in pixels per inch be done before reducing the image
My camera saves at 300 ppi at 3872 pixels wide (sometimes they are cropped which makes them smaller) and for the web I need about 500 pixels wide at 72 ppi.
I'm running AutoCad LT 2009 and I need to be able to open drawings that were created in newer versions of AutoCad, so I'm trying to download TrueView. I go through all the steps, try to open a drawing and it directs me to download TrueView again. What do I do now?
