Lightroom Mobile File sizes

I want to use LR mobile to transfer some files to my iPad. Do I need to resize and convert to jpg before setting up a folder for transfer? Do I just set uo the transfer file as a collection?

When you mark a collection for syncing and syncing is enabled, Lightroom automatically converts the collection's photos to Smart Preview versions to save space, and moves those Smart Previews to your iPad. The Smart Preview versions are a lot smaller, but they contain enough information to let you edit them on your iPad as if they were still raw. On the next sync it passes any iPad edits back to the raw files in Lightroom on your computer.
You never have to pre-convert files for Lightroom Mobile, it's always done automatically.

Lightroom export file size: why so small? How can I maximize image quality?

My image file sizes are much smaller after editing and exporting through Lightroom. Is it impossible to maintain original file size to preserve image quality? Will this smaller file size have negative impact on prints? Any help is appreciated!

My view on this is somewhat different ...
Jpgs should never be edited, except as a last resort. And it defeats the purpose of working with raw files if you export a jpg, and then edit it.
Agreed. Unfortunately there are many cameras that only output JPEG format files. The camera file (or any other original JPEG file) is your "raw" unedited file inside LR. If you need to send the file to someone else for further editing who doesn't have LR then Exporting with 100% Quality setting might make sense. I say "might" because it's still possible to get very good results using lower Quality setting JPEGs if you only re-save the file one (1) time after further editing. I agree that 16 bit, ProPhoto RGB, TIFF Export files are best for "critical" work and when using 'Edit in Photoshop' from LR.
I suggest taking a look at the JPEG compression image tests on Jeffrey Friedl's Blog. It's a wealth of information! LR's Quality settings range from 0% to 100% or 100 Quality levels. In reality there are only 13 Quality levels, which are the same as in PS.

I use LR JPEG Quality settings of 77-84% for outside printing and LR 62-69% for web posting. I've yet to see any compression artifacts using these settings and I am a pixel-peeper!

If someone gives me a jpg to edit, I always save it as a tiff and convert to 16-bit, to minimize furhter deterioration. I realize that this will not be true 16-bit - no information is added to the image - but my impression is that it will withstand heavy editing better, and not end up with a comb-like histogram.
Why not simply Import the JPEG file into LR and do all your editing non-destructively? There's no need to convert the JPEG file to TIFF unless you need to use LR 'Edit in PS.' Lightroom uses a16 bit/color, ProPhoto RGB, Linear Gamma workspace for all images even when editing sRGB JPEG files.

Maximum file size in creative cloud and Lightroom mobile?

I Am interested in purchasing the special offer for the photoshop photography program where I can move and edit photos between a desktop version of LR, the cloud and mobile LR. I use large Raw format files of about 25 MB. I saw that photoshop CC app can only handle up to 12 MB files, and was wondering if there is a maximum size limit for mobile Lightroom?

There is not really a limitation. The Lightroom Mobile technology lets you view and work with large files by creating compact proxy images on the tablet. Settings will be synced between the proxy and original raw-file on your desktop computer. Hope that answers your question. -Guido

Lightroom Mobile output file sizes

I have started using LR mobile yesterday and can't figure out how to export, share or even save to the camera roll a full size resolution photo after I do my edit. There doesn't seem to be an option to allow me to choose the edited photo output size and all I get is the edited photo at around 2000 pixels. I understand LR mobile uses smart previews and the original file imported is smaller as a result, but the 2048 pixels output is smaller than what my client requires and this forces me to use other Apps to deliver my files on the go.

120MB - WOW!
I am starting to look into the whole Adobe mobile dev tools - as apps are targetting devices with usually way smaller capabilites than common desktops - file size is possibly an important factor, right!? lol
You could take a look at some pure AS3 coding - Daniel Freeman seems to be having some fun in this direction with his non flexy AS3 mobile components library - MadComponents.

Why files in Lightroom mobile and files in the creative clouds not the same?

Why files in Lightroom mobile and files in the creative clouds not the same?
Idea was to store date in one place. I have subscribed to photographer option

Do you mean you are trying to sync files from Creative Cloud to mobile and it doesn't work? I don't know much about Lightroom. It's better to ask your question at Photoshop Lightroom.

Why files in Lightroom mobile and files in the creative cloud not the same? idea- one place(stored date) for all application ??????

Why files in Lightroom mobile and files in the creative cloud not the same? idea- one place(stored date) for all application ??????

Lightroom Mobile is not a cloud storage service. You shouldn't treat it as a way of backing up your files. You are merely storing Smart Previews of your files in the cloud space, high-quality JPEGs of your files regardless of their original format on your desktop. The point is that they are there so you can continue editing them in a Lightroom-like environment even while away from your desktop/laptop computer. The files in Lightroom Mobile can only be used in Lightroom Mobile.
This is very different from what is offered by the Creative Cloud storage, which can be used to synchronize your files between any device (that can support the individual files).
The vast difference in how each service works and its intended use is why they are separate.

Maximum file size for Adobe LightRoom?

I was just wondering in anyone here had an idea on the maximum file ( DNG/RAW/Tiff/JPG ) size LightRoom will handle given enough RAM and a fast processor?

Dear Paig,
This is a tough one as this is a scan of a B&W 6X6 B&W negative done on a very high res Scitech scanner. It is a .tif file and the file size is only 139MB. What it would equate to in MP is hard to tell. I will be trying to use LR on scans I do on a Nikon SuperCoolScan 9000 and it too renders 48 bit color tif image files.
I wounder if more RAM would help. The Dual Core 2.66 xeon processors should be plenty fast enough to deal with LT 2.3
I had read some discussions of memory leak problems with LR and it seems as though this might be the case as after 15 adjustments and nothing elso open on the MacPro to see my used RAM up to 4.5 GB indicates that something is amiss...
Thoughts anyone?

Lightroom 4 - presets and file sizes

When i apply a preset to a photo, then export it ... the file i end up with is significanatly smaller than my original file ? These same presets resulted in as large / or in most cases larger files sizes in previous versions of lightroom ...

Develop Module Presets have almost nothing to do with file size.
File Size is a function of Pixel Dimensions, File Format and Compression (if any)
I suspect you are exporting them with different settings than you were in previous versions of Lightroom.
What is the file format to which you are exporting? What are the settings for File Type, Quality, Compressoin? What are your Dimensions? How do these settings in Export differ from your previous exporting?

What happens to Raw files when importing Raw+JPG from camera to Lightroom Mobile on iPad? Only JPGs are showing up.

Hey I am Brian, and I was wondering how Lightroom mobile works again as in when importing photos directly into iPad using the camera connection kit.? This is for IPad 2. I . Like when importing raw files. now I just did a photo shoot. and I just uploaded them into lightroom 5 on desktop. the raw files are being pushed as smart priviews acroos ipad and iphone. its kinda cool seeing cr2 file showing up on lightroom mobile. when its coming from lightroom 5. but what about coming from camera to ipad.?
I thought you can import a Raw plus jpeg into ipad and it shows up as a jpeg plus raw file. well its not doing that. shows up as just jpeg.
cant wait for next update of lighroom mobile.

With this version of LR Mobile we not support the direct RAW import.

Can Olympus RAW files open in Lightroom mobile?

Can Olympus RAW files open in Lightroom mobile?

As I understand it, but I have not tried LR Mobile, you have to have the raw files on a real computer and then sync the smart previews from LR desktop to the iPad. I am still trying to get my head around a real use case for a non professional enthuasist photographer.

Fuji raw files from iPad Camera Roll to Lightroom Mobile

I can not transfer Fuji XE2 Raw files from my iPad Camera Roll into Lightroom Mobile. They will transfer from Lightroom 5.4 into mobile and can be edited which proves mobile can handle them. However not a lot of good for location use!
Does anyone else have this issue? Is there another way of transferring files within the iPad other than from camera roll?

Thanks for the quick response, although disappointing to hear. Surely that rather defeats the object!
Once you have them on your regular computer why would you then want to transfer and edit them on an iPad? I'm off on a weeks holiday and want to work on them while away.
There are other iPad apps that can import raw files but as I already use Lightroom I was hoping to use their mobile app.
What a let down!!

Organize files from Lightroom Mobile on Hard Drive

Hi! I am working on refining my workflow for getting images from my iPhone into Lightroom. One approach I'm considering is to use Lightroom Mobile's Camera Roll auto-import feature, since it works pretty consistently well, and would allow me to start rating and sorting images on either my iPhone or iPad, and do heavier editing when I get back to the desktop. My idea is I'd have an "Inbox" where images are coming in from the iPhone (either that I've shot with the iPhone itself, or transferred to the Camera Roll from an Eye-Fi card -- but that's neither here nor there), and I could sort them into other collections when I get back to the desktop.
Quick background note: I'm coming from Aperture, where I had referenced files on an external hard drive, neatly organized in folders by year > month > day, and named in <yyyy-mm-dd> - at - <hh-mm-ss>.ext format, easily searchable via the filesystem, if need be (yeah, I read The DAM Book).
My problem with this Lightroom Mobile workflow so far, is that once the images get into Lightroom on the desktop, the image files are buried somewhere in the Mobile Downloads.lrdata folder, eating up space on my internal hard drive. I'd love it if I could have them stashed away on my external drive, where all my other photos live.
So - my question is, does anyone have suggestions for how to go about moving them to that external drive, respecting the organizational structure I've got in place (folder + file naming convention)? They don't necessarily have to stay synced with Lightroom Mobile once I've started organizing inside of Lightroom on the desktop, although that would be nice. Or is this a ridiculous and convoluted way of getting images into Lightroom on the desktop? How are other people handling this kind of scenario? I'm not averse to something script-y, like AppleScript or maybe a Hazel recipe, but I could use some suggestions for getting started in the right direction.
As an aside, this all started for me when a) I bit the bullet and switched to Lightroom at the beginning of the year (the writing was on the wall, way before Apple announced they were killing it), and b) I started shooting with an Eye-Fi card in my Fuji X100S. Unless I'm shooting RAW (which I rarely do with that camera), it's so easy to sync images wirelessly over to my phone, and seems redundant to then import images off of the card into Lightroom.
Anyway, thanks for any suggestions you might have.

I have read a few post on this subject but I have not found the answers that I am looking for.
I want to take all of the photos off of my computer and put them on an external hard drive. If I am in lightroom and plug in my external hard drive, if i just move all the folders over to the external hard drive does take them off of my comptuer?
Also, what I want to do is make one folder for each calender year along with the edits made to the photos. So, If I back up my catolog and move it over with the photos, that means that all of the edits I made on those photos will stay with those photos?
With having all my photos off the computer, if I wanted to reopen a folder from my external hard drive through lightroom, will they will automatically open with all the edits still done to them?
Point 1: yes Lightroom will move them from your computer to the external. However I wouldn't recommend doing this, I would copy the files from the computer to the external using your OS and when you have verified the copy is ok and you have "Updated the folder location" in Lightroom then you can delete the folders from your computer.
Point 2: You can do this manually in Lightroom using the Sort options to achieve the older you want or craete a new catalog and import from your current one and at the import stage move the files to new folders with date order.
Point 3: yes it will but you will not be able to "work" the files that are on the offline drive unless you have generated Smart Previews.

What is te max. file size for lightroom

i have some very big files. lightroom says that the are to big to catalog. but what is the max. file size ?

There is no MAX file size.
As John points out, the limits are on the number of pixels, not file size

Fuji X-10 RAW files in Lightroom mobile

Hi!
I have encountered a strange issue with files from my wive's Fuji X-10.
I synched them to Lightroom mobile and they seem to display fine, but when I try to edit them, they get distorted and the the picture is not updated with the edit. When I switch to a different picture an back it looks normal again and after a couple of minutes the preview is updated with the changes.
this is how it looks like:
Obviously my wife is not overly satisfied with this workflow
Any pointers on how I could use these files in Lightroom mobile?
tks
