.jpg file size preview quit working

Using CS5 extended (v.12.0.1x32) in Windows 7 Entp (64bit): My save-as dialog has quit showing a preview of .jpg file size regardless of where the quality slider is set. This feature was working fine, and just seemed to quit. Now all I get is the short, horizontal line in place of a number, and no matter how long I wait, no file size number appears.
Any ideas?
Thanks in advance,
ACB

Thank you very much for the suggestion. Unfortunately the problem persists.
Turning PS CS5 off and back on -- problem still present
Delete preferences file (via CTRL+SHIFT+ALT at startup) -- problem still present
Delete preferences file (xx...xx.psp) via search and delete -- problem still present
Reboot of OS -- problem still present
Roboot of OS, followed by steps above, followed by Reboot -- problem still present
Excellent idea... I hadn't thought of it; I wish it had worked. I'm open to any other suggestions.
Thanks,
ACB

How to reduce jpg file size, not pixel dimensions?

I am preparing images for the web and I really have 2 questions: one about gifs, and one about jpgs.
My standard procedure is to reduce the image to the desired pixel dimensions at 600 dpi
That gives me a crisp small image. then I either use it as is if the file size is low enough (I try for under 600 kb) or convert it to a gif with the save for web and devices tool.
So here are my 2 questions (I will count this solved with either answer)
1) When I convert to a gif I have the 4 boxes: one with original size, the other 3 with options but often the options are too low res for me How do I change my 3 options to start at a higher gif res?
2) If I try to reduce the file size of the jpg in the image size box I set the resolution lower ( 400, 300), which lowers the pixel dimensions and the filesize, but I don't want to cahnge the pixel dimensions. And If I reset the pixel dimensions back to the size I want them, even though it is a lower resolution the file size doesn't change. How to reduce jpg file size using only the resolution, not pixel dimensions? PS I have tried messing with checking and unchecking the 3 little boxes( scale styles, constrain proportions, and resample) but nothing has worked.

Gif is not a great filetype, especially if you want a crisp image. What are your pixel dimensions?
For web, it makes no difference what the dpi is, only the final pixel dimensions so once you have that as you want, use 'Save for Web and Devices' and you can lower the quality - 100% being max and 0% being lowest. I wouldn't save anything below 55%. For a 600kb image, your dimensions must be rather big.

Cannot open jpg files in Preview? Error message "may be damaged or use a file format that preview does not recognize".

For some reason I cannot open jpg files from a co-worker who previosuly sent files without any problems. I just bought a MacBook Air with OS X Lion & Preview won't open the files. She sent the same files to another co-worker who opened without any issues? Help! Anyone have any suggestions after having the same or similar problem?

I don't have an answer as to why Preview doesn't want to cooperate, but if you only need to view the jpeg's and do nothing else to them, you can use two FREE applications that come already pre-installed on your Mac... Those are iPhoto and Safari. Just drag and drop over the application icon.
You can also find several FREE photo viewers in the APP STORE.

** Reduce jpg file size...returns black image

Hey Guys,
I have this function to reduce the image file size.
It works but returns a black image when I view it.
This code is what I have found on other boards...I just can't seem to get it to work..
Any ideals??

Hi Andrew,
Thanks for your reply..Your links sent me to this ...
Page Not Found
We are sorry, the page you have requested was not found on our system. >Ahh. That is because I foolishly hand edited those links and did not check them. They included 'api' twice.
In any case they were simply the links to the javadocs for those two classes.
Search [google for bytearrayoutputstream|http://www.google.com.au/search?hl=en&q=bytearrayoutputstream&meta=] and you will end up in the same or similar place.
As to using them, you simply put an appropriate ByteArray stream in place of the other streams (e.g. File based) that you were using.
I'd have to search for an actual example, but you could do the same (probably faster).
Edit 1:
Adding 'imageio' to 'bytearrayoutputstream' as a search led to this as top hit [Memory Efficiency of BufferedImage and ImageIO|http://forum.java.sun.com/thread.jspa?threadID=5261937&tstart=0].

Reduce jpg. file size

a website requires jpg. file size to be reduced to 5000kb. i'm at 1.1mb. how do i reduce it to the required size?
rsvp...

5000kb is 5 times larger than 1.1 MB
Anyway: File -> Export. In the resulting dialogue "Size" refers to the dimensions of the photo (length by breadth) and Jpeg Quality refers to the file size. Lower Quality means smaller file size.

Iphoto increases jpg file size

Hi,
I've first noticed that iPhoto is re saving the AutoRotated images when importing them. I've realized this after seeing a lot of pictures in the Modified folder, when I've actually haven't done any editing on them...
But, more importantly, the JPG file size of the rotated image increased considerably. I've looked at the metadata with the exiftool and found that iPhoto is saving the JPG using the Big-endian byte order. I suspect this is the cause of the increased file size.
A concrete example:
mifoto0342.JPG 2986371
mifoto0342_iphoto.jpg 3765579
- Pancho

All other things being equal, the endianness of the EXIF will not affect the file size.
There must be something else that is changing in the file. Either the image is being recompressed (god forbid), or lots of metadata is being added (more likely).
- Phil Harvey

Reduce File Size doesn't work!

When I click the (new) option 'Reduce File Size' in Keynote '09 the app prompts a estimated new size which is smaller than the current size. When I click on 'Reduce' the app doesn't do anything except for showing an error report which tells me something like: "..the file size was not reduced", for all of the files included. They are just regular .jpg/.png and .psd files. Did anyone else notice this bug..?

I'd say if it is a very large file with multiple large images, it might not be actually freezing, just taking its sweet time.
It's why I leave Activity Monitor running when I use iWork applications.
This way, I know ifd the app is dead or if it's heavily busy.
Either that or it has nothing to do. It trims and reduces the resolution of bitmap images to 72dpi. There will be a fair bit of work if you have transparency in the document.
It doesn't do a very good job IMHO and to reduce the file by 90% is a big ask.
The 'Reduce FileSize' feature isn't linked to the 'export to PDF' feature.
As explained, before applying "Reduce file size" it's good practice to "Reduce Image File Size".
This will drop the parts of the pictures which aren't displayed.
The asked task doesn't imply a reduction of the pictures by 90%.
As I already wrote several times, it's more efficient to crop images to the really used area *_before inserting them in a Pages document_*.
A Pages document is huge by nature because the Index.xml file describing its contents is highly verbose.
If the document was saved with the 'embed Preview.pdf' feature active, the size of this PDF is adding a lot of used space.
I'd print to pdf and reduce the quality in Acrobat Pro.
Most of us don't own Acrobat Pro.
I feel that it would be a bit silly to buy an application whose price is : 450$ as a complement for a 80$ set of applications.
Before doing that, I would
(a) crop pictures before inserting them
(b) try to enhance Pages behaviour for free installing enhanced PDF filters.

Question about RAW to JPG file sizes

Hello all, I have a question/concern in reference to file size changes when converting from RAW to JPG formats in PSE6. I've recently purchased a CANON 50D, and have started shooting in RAW format (actually RAW2+JPG). I have the CAMERA RAW 5.2 plugin and my workflow process is something akin to this:
1. Separate all RAW and JPG images into their respective folders.
2. Open the RAW folder in BRIDGE, and then open up a CR2 file. CR2 file is approx 15MB at this point, as reported in Finder.
3. Perform various corrections in ACR52 to the file, then do as SAVE AS to a DNG file.
4. Next step is to OPEN IMAGE, bringing it up in PSE6.
5. Make any necessary corrections to the picture, and then do a SAVE AS to a new file name and folder, selecting JPG format.
6. Selection MAX QUALITY from subsequent dialogue box, and SAVE.
When the file is saved, its now down to a mere 2.1 or 2.2MB, and when viewing its properties (vs. the same file that came from camera in JPG format), its down from a 44x66" format, to somewhere around 4x6" and 240dpi.
I've been doing some reading on this over the weekend, but cant explain away the severe loss in file size, and whether this is right, or if I'm doing something wrong in the process.
Appreciate any advice or suggestions to help improve my work processes, and ultimately the final photos!

Regarding your file size questions, have a look at this thread and see if it answers some of your questions:
http://www.fredmiranda.com/forum/topic/741532/0
> When the file is saved, its now down to a mere 2.1 or 2.2MB, and when viewing its properties (vs. the same file that came from camera in JPG format), its down from a 44x66" format, to somewhere around 4x6" and 240dpi.
Dimensions and resolution are related and multiple combinations can be produced from the same number of pixels. For example, your 50D at maximum image size produces 4,752 by 3,168 pixels. This full-size image could be printed at:
- 19.8 x 13.2 inches at 240 PPI
- 47.52 x 31.68 inches at 100 PPI
- 7.92 x 5.28 inches at 600 PPI
As you can maybe see, talking about dimensions and resolution doesn't make much sense until you are ready to consider printing. Note also that I used "PPI" or Pixels Per Inch since this is the slightly more correct terminology. DPI or "Dots Per Inch" is usually a reference to how a printer lays down the ink drops onto the paper. Many printers actually put more "dots" on the paper than there are pixels. Many people and companies use DPI when they mean PPI.
Now in your case you are apparently starting with an SRAW2 raw file. SRAW2 files from the 50D have a reduced number of pixels and are 2,276 pixels wide by 1,584 pixels high. At 240 PPI this would allow you to print the image at 9.9 by 6.6 inches. If you are ending up with something smaller than that, it means you have either re-sampled the image (changed the image so the same image is displayed with fewer pixels) or you have cropped the image.
Hope that helps.

JPG file size differences in ACR and PS

Camera: Nikon D80
Photoshop: CS3 Extended v.10.0.1
ACR: version 4.3.1
Saving from ACR, Q=9 -> 1,2Mb
Saving from ACR, Q=10 -> 1,8Mb
PS, Q=11 (no thumbnail) -> 3,1Mb
PS, Q=11 (with thumbnail) -> 3,1Mb (no difference)
PS, Q=12 (no thumbnail) -> 5,8Mb
PS, Q=12 (with thumbnail -> 5,8Mb (no difference)
Save for Web, Q=90: 3,7Mb (larger than PS/11)
Save for Web, Q=100: 5,8Mb (same as PS/12)
1.) Why ACR saves much smaller files?
2.) Why there isn't difference when saving with thumbnail or not?
3.) Why the different methods?
4.) Is any of them better? If yes: why the other? If not: why does it exist?
Saving from ACR produces much smaller files than any other known RAW converter. I've tried Bibble, Lightroom, CaptureNX, DxO and all of them created nearly the same size as Photoshop does. So the most important question: why ACR creates so small JPG files?
Thanks in advance!

Huhh,
the question isn't stupid, just seems a little bit strange in my point of view. But you're right, i must confess. So halfway i am the stupid, not the question (and not the software).
But when i choose 'maximum' in ACR it gives me the 10, and i thought maximum is the maximum. For me it tells about the highest possible quality. There is no value bigger than the maximum.
I've never realize that in PS the way is exactly the same like in ACR! In PS the maximum is 10 too!! I'm always enter the value by the keyboard and never choose a preset. And in PS there's a slider showing the full scale and the entered value, so on that i can see that there's life after the maximum. in ACR the missing slider suggested me that 10 is the top level. But now i've entered 11 and 12 and gave the same sizes as i gave from PS with 11 and 12.
So i can conclude that the GUI of ACR isn't perfect (OK, i *must* now it uses the same engine/values like PS), but the method behind the scenes is perfect, like in PS. Sorry for the trouble and thanks for the very fast answer!

Elements increases JPG file size - case # 0181346249

I just asked this of Adobe. Couldn't find anything this specirfic in the forums, anyone have anything on this? Thanks in advance. Lee
~~~~~~~~~~~~
On/about 12/4/09 I upgraded Elements from 6 to 8. Since that date I have discovered that the file size for all JPG files managed by Elements has been increased by 5304, 5309 or 5310 bytes. This has complicated my backup scheme, now the backup program wants to replace all said files, in excess of 16,000 pictures.
What is Elements changing?
Is this documented?
The attached JPG shows the original file on right, the Elements managed file on left. The far right column shows the file size increase.

It may be that you have the Auto-Analyzer set to run automatically, and it has added some additional metadata (EXIF) to each of your files.
The PSE 8 Auto-Analyzer has some severe problems, and I recommend that you never run it. It will corrupt your map locations, split your video clips into "scene groups" that are hard to get rid of, modify the date/time of every file, crash frequently, make your computer very sluggish, and litter your folders with temporary files:

LR3 Export jpg File Size Inaccurate

I have a CR2 file 4752 x 3168 and 22.22 MB that I want to export to jpg. I select resolution of 72 with dimensions of 1024 x 683 (largest size of side is 1024) with a file limit of 150KB. I get a file that is 155 KB with the indicated dimensions/resolution. I set the maximum file size to 130 KB and get a file that is 155 KB. I have to set the limit at 100KB to keep the file size under 150KB. I can do the same thing in CS5 using the Save to Web without any problems.
It should not be that difficult to convert and resize an image for web imports limits.

Thank you. Maybe they will get everything corrected before they release 3.2 for production.

Mike

RAW Conversion to JPG file size question

I'm fairly new to Lightroom and have noticed when I convert from RAW to JPG my approx. 8MB RAW files become approximately 2-3MB JPG files. I have the program set to convert to JPG at the highest possible quality. I've had clients ask about the file size and would like to be able to explain this to them in simple terms but I first need to understand why this is the case myself! When I used a different processing program the converted files were only slightly smaller than the originals. Please explain!
Thanks!

It depends on the quality settings you use. JPEG files have I think 12 quality settings, with 12 being pretty big, and 8-10 being reasonable compromises.
This is lossy compression, so data is thrown away. The quality setting determines how much info is thrown away.
Only thing you can really do is export at a few quality settings and compare them, to see if YOU can see the difference.
For me, I don't really care about minimizing file size so I always choose highest quality.

Iphoto 8 jpg file size

On my desktop I have a JPEG picture sent to me via email from an Iphone. If I click get info the file size is 914.8 kb (936,888 bytes). After I import the photo into Iphoto 8 and click on it in the event window the information box in lower left has size 393KB. What is happening and am I losing picture quality. If I am how do I minimize any loss in picure fi

Is it a portrait oriented photo? If it is then iPhoto created a modified version which is rotated and underwent one level of JPEG compression.

Why does iPhoto only import digital photo files at one-half or less of the original jpg file size?

My 24" 2008 iMac, running 10.5.8 and iPhoto '08 (300 GB harddrive, 67 GB avail, 2.8 GHz Intel Core 2 Duo, 2 GB 800 MH sdram), only imports my digital photo images directly from the camera at about 1/2 or less of the original file size. I thought it might be my 12.2 mgp. Samsung camera, until I just a 14 mpg. Lumix, and its doing the same thing. A 5 mg. images imports at around 2.4 mgs... a 14 mg image imports under 6... Its always done this, but until I bought the new camera, I assumed it was my peripheral issue.

Hi, I wonder if it's just maybe compressing them, highlight one in iPhoto & click on the little i icon for info, what is the size in Pixels compared to the original?

Picture jpg file size is small when using Preview?????

When I connect my camera and iphoto opens, I use it to save the photos. All fine. They go into a folder within the '2007' folder.
Then when I click to open the file using Finder, the picture is 1/4 the size of the original I was just looking at with iPhoto. ???? I can not figure out what's going on. Why is the picture with Preview so small?
Thanks a lot!!!!

Allan has posted some good resources. I would add that if you have additional questions in the future it's best to post them on the iPhoto Disscussions forum rather than the OS X Tiger forum. Here's a link to the iPhoto Discussions forum:
http://discussions.apple.com/category.jspa?categoryID=143
There are a number of iPhoto experts there to field questions associated with that application.
By the way, you can learn a lot by just playing around with iPhoto. iPhoto keeps a copy of your original no matter how many times you change a photo. So, generally speaking, you don't have to worry about doing something you can't recover from. It's only when you access or change photos in the iPhoto Library folder from outside the application that you run the risk of screwing something up.
Have fun.
