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?

Shedding light on export settings and file size

I am trying to learn about exporting images and file size. I have a combination of RAW and JPEG images in my library. For the sake of this discussion, I am going to limit this to JPEG's. I need to export my images, so that I can then upload them to an external photo processing site like Kodak.com. I was going to export versions of my images because I have made adjustments to many of them. I was going to choose the top level preset of "JPEG - original size." For the sake of example, the file that I try exporting this way has a file size (in Aperture) of 1.94 MB. After exporting it (with a DPI of 72) and a color profile of sRGB IEC61966-2.1 (I am not sure what the significance of the DPI and color profiles are either), I get an exported image with a file size of 4.6 MB. When I export the master image, I get a file size of 2.0 MB. I'm completely confused and at a loss as to what is going on here.
Can someone please shed some light on how to go about exporting images so that I can be certain that I am exporting the best quality image possible.
Also, and possibly more importantly, I export image files to sites like MobileMe Galler, Flikr and Phanfare, etc, for the purpose of archiving my images and now I am not sure if the files I am exporting are of the optimal most quality they can be. Do these settings have any bearing on the images that are being sent to my archival folders?
Thanks in advance for any input on this important topic.

This confusion is because of the way Jpg files handle data. Jpg is a kind of file that compresses data to achieve a balance between image quality and file size. The jpg file that your camera saves to disk is also compressed, that's why the difference in size between a 2 MB jpg and the same image in Raw is for example 18 MB.
Jpg is a lossy compression format, every time you save a jpg some compression is applied, say after editing in Photoshop. Aperture must be reading your jpg masters to export jpg files to disk, so the difference in size should be the compression quantity applied to the newly created jpg file. I could have a 1 MB jpg file previously compressed with a quality level of 7, but if I export it at a compression quality of 10, the file could easily become a 2 MB file. The problem is quality doesn't increase with file size when the original file is a jpg.
Also some files include a preview image inside the file, increasing the final file size. The color profile embedded should't increase size by much, since most camera jpg files already include a color profile embedded (color profiles tells computers to display color consistently between applications and peripherals like printers. sRGB is widely used for images published on Internet).
As for the images you are sending to the archival folder, I would suggest you to export the masters, instead of exporting a new jpg file from an already compressed jpg master.
I know this is a complex subject so I hope I haven't confused you.

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 ??????

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.

InDesign Transparency Effects - Problems with Image Quality and File Size

Hello,
We are experiencing new problems exporting InDesign files to PDF.
To summarize, though our largest workflow is to create files for offset printing, we also deliver our work to PDF for mounting on a website so our clients can download directly from the web. Our new problem is Transparency Effects, and creating a PDF that will both have a high quality (or resolution), and be a small file size.
We are working with multiple page documents (24 to 48 pages), and would very much like to work with InDesign Transparency Effects. However, after spending much time testing a variety of PDF types, we are finding there is a radical difference between quality and file size. I was curious if anyone has had these problems, and if there is a simple answer. InDesign is an incredible program that allows us to design on the fly with Transparency Effects, but, if we are going to experience these problems, we will have to eliminate these wonderful tools.
Can you help me or lead me to information online that will help.
Thank you,
Lain

Please don't post in multiple forums. Your question has nothing to do with the PDF language and specifications, but rather PDF workflow or InDesign. I've responded to your other posting and am closing this thread.

I print 2 pages to pdf and file size is 600k, I print 1 additonal page and file size goes to 6M, what would cause this (graphics are same on all pages)

I know the colour graphic shading in the document that causes the issue of larger file size, but it doesn't make sense that printing 1 additional page with same information as first 2 pages would cause this.

Pixel Dimensions and File Size

Can anybody please explain the relation between pixel dimensions and file size?
Being naive, (or straight-forward if you prefer) I had assumed that pixel dimensions wide times pix dimension high = file size. Wrong!
For instance a .JPG file 374 X 500 has a file size of 41,275 bytes. But 374 times 500 = 18,700 so the two are different issues.

Thanks Rich. It kind of sounds like you know something about this.
I see 1 pixel, and 24 bit color would make 24 bits at 8 bits to a byte, so there's the 3 bytes.
I selected a certain photo and used the APPLE i command to see if could find if it had 8 bit color or, whatever. That infomation was not on the info function, but it did say something about RGB color profile.
Is 8 bit color a near certain bet in most applications, or was that just for the sake of illustration?
I Googled 8 bit color and go to a Wikipedia Article
http://en.wikipedia.org/wiki/Color_depth
which explained a lot, but its more technical depth than what I'm prepared to deal with. The net net, as far as I can tell is that image size (before compression) is dimension times color depth in its native mode, but I suppose what the native mode is and what the displayed mode is could be separate issues?
I was under the impression that the compression in JPG formt files comes out, or is decompressed, when the photo is printed or displayed? No?

Lightroom Keeping Original File Size on JPEG Export

In Photoshop Light room, when I make edits to some JPEG files in a library and leave some unedited, I want to then export the JPEG files, keeping their original file sizes. The default quality setting is 60%, but this reduces the file sizes.
How do I keep the original file sizes?
Thx.
Tony.

> The default quality setting is 60%, but this reduces the file sizes. How do I keep the original file sizes?
All of the Export Presets can be edited and the new settings made to be default. Alternatively you can set up your own, new, presets to your own specification.

Best Sequence Preset and File Format for Editing HD?

I'm using Premiere CS4 and I'm starting a new project that was shot in HD. I'm dealing with multiple file formats, as several different types of HD cameras were used. This is for a feature documentary, so I need a balance between maintaining image quality while sticking with a format that my machine can handle smoothly. Two questions:
1. Which HD preset should I commit to for the project (DVCProHD, XDCAM, etc.)?
2. I want to keep things nice and tidy and convert all of my footage to the same file type. I've found that Premiere works best with AVI files, but I'd like some input on what file format and codec you recommend. I took a stab at converting some files to Microsoft AVI format using the V210 10bit YUV codec, but the file sizes are huge and my system (quad-core processor w/ 12 gigs of RAM) still can't handle smooth playback with them.
Recommendations? I'm open to purchasing a plugin, 2nd-party file converter, etc. if necessary.
Thanks,
Mike

I would be inclined to use a seq that matches the most prevelent source video you have.
If you decide to convert everything to one format; both P2 and XDCAM formats are a pretty good balance of file size vs quality IMHO. (both edit very smoothly)

Export Options_Automatic Stacking and File Size control

There is a big hang-up in work flow, and I'd assume it's the same for many professional photographers.
It would be great to be able to Export an edited photo (tiff, psd, jpg, RAW), and during the export be able to specify maximum file size (as you can control in Photoshop's Save to Web command), and then also be able to have Lighroom automatically stack the exported image with the original.
This is a big hang-up when you're finished editing multiple sized copies due to different media, and then you have the final web-sized image for your photo gallery. CUrrently, I have to go to Save to Web in Photoshop, and then save it to my desktop. Then I have to manually import that compressed jpg into Lightroom, and put it into the original library or collection.

Yes, the ability to export to a given file size would be awesome for those of us who post many images to the web.
Also, being able to export and automatically add the exported file to my catalogue (Same as when you edit in PS) stacked with the original, would really aid my workflow.

Animated GIF--Quality and File Size

I'm having a hard time getting a quality image and a decent file size.
Even if I save animated GIFs and open with PE an try to resave them, the motion is choppy and the file size is more than double the original.
For example, the following image is less than 10K and plays quite smoothely, but no way can I duplicate such a simple graphic under 10K:
http://thequackshack.com/forums/radio/style_images/Borderli-546/ad_banner.gif
It also seems that others can control the duration of frames individually...
Most of my GIFs end up around 300K, which will not be accepted. A compromise of poor quality will also not be considered.
What can I do?
I've tried lowering Dither and colors, but the results are poor. My graphics will not be used if they are so large or of poor quality.
Here is a couple that I made:

I am not an animation expert, but I copied two of your examples. On the example you say is under 10K, there are about 35 layers. On your example there are about 65 layers. I'm wondering if reducing the number of layers would get you what you want.
As for controlling duration of frames, I assume you want Frame 1 to be 0.5 second, Frame 2 to be 1 second etc. I think PSE puts a uniform time between frames. This can be adjusted, but it is adjusted all frames. One workaround I've seen is to copy a layer. So if the timing interval is 0.5 seconds, you would have the same image show for 0.5 seconds X 2 = 1 second.
This is about all I know on animated GIFS.

Maximum Number of Pages and File Size for PDFs

Assuming that your computer has ample CPU, memory,and storage, how many pages and what file size does Adobe recommend that you limit a single PDF to using Acrobat Pro XI in order to avoid any issues.

I don't know whether there's a limit on number of pictures you can add to a book
as long as they are contained in 100 pages, which is the maximum photo pages on a book.

Photoshop PDF and File Size...And Into Acrobat

I have an 8x10 at 144 ppi
I Save As Ps PDF> Compression> Options> DO NOT DOWNSAMPLE
Compression: JPEG> Image Quality: MAX (gives me 6mb file)
Compression: JPEG> Image Quality: MEDIUM (gives me 9mb file)
Ps> Save As JPEG gives me 840kb file
HOW can I get Ps to Save a PDF in the JPEG file size?
I want to set the resolution and quality in Ps and SIMPLY move it to a PDF...

Bingo, unchecking Preserve PS editing fixed the problem...thanks
