Lightroom :: DNG File Size
Oct 18, 2013Running LR 4. Recently noticed that when importing CR2 files and converting to DNG that the file size almost doubles. "Imbed Original" is NOT selected in the Preferences menu.

View 8 RepliesMy picture’s original size was 108.2 MB in tiff. After I developed my photo in Lightroom and exported the new image, the file decrease to 50MB in tiff. Why did Lightroom decrease the file size to more than half the original size? Is there a way to increase the exportation file size to that I may develop a large size print?
View 7 Replies View RelatedI was *so* hoping that we'd finally be able to filter (or create a Smart Collection) based upon file size.
There are many reasons why this would be useful but the thing that trips me up every once in a while is that I'll forget to flatten my layers in Photoshop and the resulting tiff could be over 500 MB! Everyone once in a while I'll manually find the large files, flatten the layers, then re-import them into LR - in the specific case I mentioned the file was reduced to 17MB.
I am running LR3.5 on an iMac. I created a slideshow yesterday that contained 40 images, and exported as a PDF.When I emailed it to three friends and myself, it bounced (too large) from three of the four friends I sent it to.
How do you check the file size of a PDF slideshow? how to share a slideshow without bumping info size limitations?
LR 5 shows them as 16mb files. PS CC shows them as 91mb files. Finder shows one as 95mb and the other as 234mb.
I'm pretty new to LR and have been doing LR editing and then using NIK plugins or Perfect Photo Suite and sometimes PS, always saving them back to LR and printing in LR. Often I wind up with 3 or 4 files. Part of this is because after printing , I export the file to my "printed" folder which allows me to easily find all I feel were good enough to actually print at some later date. I'm sure some of this is that I still am not completely trusting LR because I'm still surprised with things like this from time to time... I'll get there.
But how can I figure out why these file sizes are so disparate?
In lighroom 4 my image shows as being 9.9 MP. In mac finder it shows as being 59.2 MP.

I am importing raw files from the X100S, converting them to DNG files, and they come out at around 55Mbytes per picture. When the quicker startup info and the Raw file is included in the DNG file, the size goes up to around 70Mbytes.
Specific environment: OS X latest version 10.8.4, iMac about 3yrs old.
How would one search and sort by file size? I don't see a way to do that. I'm trying to delete the largest files that have no future in my catalog.
View 2 Replies View RelatedAfter scanning a silde as a TIFF, when I import into the Lightroom library the file size is only about 1/6th the size of the file scanned onto my hard drive. A 50MB scan becomes an 8MB LR file. If I take the file into Photoshop it is still 50MB. I tried saving the photoshop file with a different name and then bringing into LR but it still ends up at 8MB. I get the same problem using both VueScan 9.0.90 and Silverfast 8.0 scanning software. How do I keep the original file size?
LR4.3 is up to date
OS-X 10.8.2 is up to date
Pacific Imaging Electronics Powerslide 5000
Imaging software is VueScan 9.0.90 and Silverfast Ai Studio 8
i'm currently using LR 4.0 and found a problem with file export.
I have two tiff files:
Tiff 1: 283MB, full resolution ( 2336 x 3504 )
Tiff 2: 233MB, full resolution ( 2336 x 3504 )
Export witht: 574 x 1000 image width
JPG 1: 168kb
JPG 2: 194kb
Both jpegs have 600px x 887px (fram with mogrify plugin#) and 100%jpg quality.
Whe I set a limit to file size of 154kb, I receive following:
JPG 1: 102kb
JPG 2: with error ( couldn't create jpg which fit's the file size limit of 154kb )
If I export the second tiff manually with 90% jpg quality and no filesize, I get:
JPG 1: 114kb
JPG 2: 135kb
So it seems that the "limit file size" isn't really working.Also it seems that Valus between 92 and 100 ends in: same as 100.
I had a question on reducing the image size after editing in Photoshop.
After doing my changes in Lightroom, I typically make edits in Photoshop and then do some final touchups back in Lightroom. The RAW file from my camera is approximately 24 MB. After making my edits in PS, the TIFF file it produces (with all layers flattened) is in the 60 MB range.
My question is, if before sending in back to LR, I change the image size in PS say to 12 MB or so, am I basically creating a lossy jpg file? Meaning -- by reducing that TIFF file size down to 12 MB am I throwing out important information such that when I go back to LR I am losing information and won't have as much control as the 60MB TIFF file?
keep upwards of 80MB per image (due to the RAW + edited file). I don't want to lose imporant information so I will if I have to, but would prefer not.
I notice that when I use Lightroom 5 to rename the pictures contained in a folder, the folder size is reduced afterward. For example, a folder containing 349 jpg files was 1.52 GB but after renaming them, the folder size was redusce to 1.30 GB.
View 8 Replies View RelatedAfter import to LR 5, file size goes from 20-30mb to 40-50mb. Updates are current, no preferences have been changed. This issue happens with two difference cameras.
View 2 Replies View RelatedI take a large number of event images and the usual client request for images being sent to the press is image size rather than resolution, dimensions or other requirements.
Clearly in LR3 if the client has requested 3MB jpg the easy option is to after processing take my Canon 5d mkii RAW file and just hit export to max 3MB jpg.
My question is is it better - ie image quality better - to export by resizing longest edge to approx 3000 px and exporting to jpg which results in a similar file size, though different pixel dimensions? Or are they effectively the same?
Where can I turn on options on an image and get the file size and type?
View 4 Replies View RelatedI’m wondering if there is a rule-of-thumb that one can use to predict the approximate size when exporting a raw file in Lr to a jpeg file. For instance, would an average 25 Mb raw file convert to about 5 Mb jpeg with the Lr export quality set to 100? To about 3.5 Mb with a quality of 80? …
I know the size will vary, but when I am exporting a collection of raw files and I have set the max file size to a certain amount, Lr sometimes won’t convert all the images because I have limited the file size too small. I’d like to be able to get a handle on some sort of quality/file size relationship before I start the export process.
When I import a 26.8 MB (5616 x 3744) CR2 RAW file from a Canon 5DMKII into Lightroom 4.4 and then export it as a JPEG sRGB Quality 100 file, it's size is 13.4 MB. When I do the same thing in Aperture 3.4.3 the exported JPEG file size is 20.8 MB. Am I doing something wrong in Lightroom?
View 1 Replies View RelatedI love LRs ability to create great watermarks. Only thing, they seem to come out (from DNGs) at about 3 mb apiece (quality setting at 79) - super large. So I clicked the box to limit file size, and I chose 300k (for web), and it says "could not create a jpeg that met your limit".
View 5 Replies View RelatedHow come the file size when I export from Lightroom is substantially smaller than the original file size? My original image file was 6MB, but when exported from zlightroom the file size for that file is only 2MB. I want to export full size files so that they can be published or enlarged.
View 7 Replies View RelatedIs there a simple way to limit the file size of the photos selected in LR3 for a photomerge in PS5?
I have found that without limiting the size, the panoramas generated are very large - 1GB or greater.
I've found an work around by opening the photos in Bridge and then in Camera Raw where I can reduce the file size before using PS5 for photomerge. After I've done this, it's a bit of a hassle to get the panorama back into LR3. The benefit of this approach is that it speeds up the processing significantly and downstream with any subsequent processing since the files are just large and not ginormus.
If this isn't possible, this seems like a good idea for LR4.
I have 279,94 GB in pictures files and my lightroom catalog backup file is about 272. I tried deleting older backups but had to put them back because Lightroom crashed and had to recover. I moved the Backup folder to an external disk, but seems that I cannot do anything about the files that are in the fomer folder in my computer.
I have only 15 GB left in my 1TB Hard disk iMac !!
how do I make sure the files i export from lightroom to hard drive are the same large files i imported to lightroom from my camera? I have worked on a collection for many hours and following export to hard drive the file sizes are tiny??

View 3 Replies View RelatedCan someone please explain to me about file sizes and image dimensions. I have to put together a collage which is 165mm high by 258mm wide. If I click file new and choose default resolution (72) then the file size is ok, if I type in 300 dpi the image becomes huge.
If i chosse 300 dpi then the images I was going to use seem tiny on such a vast workspace - Im confused why does the canvas become so large when changing resolution?
 When I save a file to jpeg the image size in photoshop remains the same as it was as a tiff file BUT according to the information that comes up in windows properties the file is much smaller (300k vs 2.9mg).  Can you advise me which is the correct file size?  If the correct size is the one showing in windows (300K) does mean that the file compressed in JPG and lost a lot of information?
 and if this is the case how can I prevent that from happening and still save the file as a JPG?  [ I would like the image to remain the size photoshop shows it to be] . Thank you very much.
I have a prob with the Paper size and the Cell Size not matchng in LR4 using a Sony UP-DR150 printer.
I'm running on Windows home premium 64bit,
i have installed the Sony 64 bit printer driver.
When i print the photo, it prints to the size 4.31 x 3.12 on the 5x7 paper.
I'm shooting both full-size raw and SRAW with my 5D MKIII - Is there a way to have Lightroom sort these duplicates by size?
