Difference in file size in photoshop and bridge

when I save an image in photoshop (file size 26mb) it shows as a 70.7 mb in bridge or window explorer. Why?

Lets take a look at the Image Sise Dialog. Nothing in it indicates anything about any file size. One number in it I have never been able t figure exactly how Adobe come up with and the is Pixel Dimensions Number all others I understand.
Below is a screen capture of the dialog shows 91.4M ???
3264x4896 is the 3:2 my Cannon 1D4 16MP the first calculator is
3264x4896=15980544 I can by the camera sensor is 16.1 MP but only delivers an image 15.98MP
Its 16bit color so each pixel has 3 16bit values for RGB 6 bytes per pixel
15980544x6=95883264 bytes 95.9M not 91.4M
If 91.4 is in hex M 1028 is 1K so 1M 1028000 bytes is 1M
91.4x1028000=93959200 still short of the 95883264 bytes required so I do not how Adobe come up with the 91.4M #
Any way 3264x4896 is canvas size. Has nothing to to with file size.
Photoshop also supports layers and layers can be canvas size or larger then canvas size as well as smaller then canvas.
Additionally layers can contain embedded object and object could contain a layer file like a placed PSD image.
The center section Document Size is the documents Print here you see the document currentle has a 240DPI resolution
3264pixel width / 240 dpi = 13.6"
4896pixel height / 240 dpi = 20.4"
The bottom section is the control section. With resample NOT checked the top can not be changed Pixel Dimensions will not be changed nor would File size. And all three values in print size are linked. You change one value and Photoshop will chage the other two for you. With resample NOT checked the other controls are not settable. Pixel Dimensions are not change so no interpolation and no aspect ratio change.
With Resample checked Constrain Proportions will link width and height to preserv the current aspect ratio and not distort the image.
When you save a document file format is very important layered flat compression all play a roll. It very hard to even guess what the file size will be.

Different file size between Photoshop, and finder/explorer?

I posted this discussion last week http://forums.adobe.com/message/5820325#5820325 and have now determined that some part (still don't understand how/why) of my scanning/saving workflow- is creating a new layer "Layer 0" to replace the locked Background layer. This is causing the image to double, or triple in size. However, upon opening the image in Photoshop, the size of the image doesn't match the size viewed in finder, or Bridge....Does anyone know why?
23mb in Photoshop.
44.81mb in Bridge.
44.81mb in Finder
EDIT: There is only one later in this image. No image edits, except for cropping. You can see in the last image, how using an identical workflow, some images are saving correctly (20ish mb) and some are double.

Assuming you are deleting the spurious Layer 0, have you also then flattened the image before saving to see if that makes a difference?

Adobe Lightroom, Photoshop and Bridge does not recognize the raw files from my Canon Mark III 5D Camera.

Adobe Lightroom, Photoshop and Bridge does not recognize the raw files from my new Canon Mark III 5D Camera. How can I get my files open to view and edit? I am using LR3, Photoshop CS3 and Bridge CS3. Do I need to upgrade these programs or is there another way to get these programs to recognize my files?
When I try opening the raw images in Lightroom, the thumbnails say "Preview unavailable for this file" ... when I click "import" an error message pops up that says "The files are from a camera which is not recognized by the raw format support in Lightroom."
When I try opening the raw images in Photoshop, an error message pops up saying "could not complete your request because photoshop does not recognize this type of file."
When I try opening the raw images in Bridge, it just shows an icon with the file name and CR2.
Please help!!!

Unless I missed an announcement, today, LR6 isn't available, yet, right? Only Adobe employees and beta testers would know what LR6 does differently at this point and they're all sworn to secrecy.
LR5 is available as a standalone version.
PS-CS6 is available as a serial-number-licensed version.
PS-CC + LR5 are also available as a Photography Plan subscription for $10/month with a minimum OS versions of OSX 10.7 (and probably 10.8, soon) and Windows 7.
Bridge is part of PS, not a separate program.
LR5 standalone and LR+PS-CC plan are both available on this page: http://www.adobe.com/products/catalog/software.html
PS-CS6 can be found on this page: Creative Suite 6 which can be found by searching www.adobe.com for Photoshop CS6 and clicking the Buy link in the on-the-fly search results.
As with any new Adobe software, it might be wise to run it in trial mode for a few days/weeks to see if it works well with your computer, before purchasing and finding out you might need a new computer, first.

Hi - for any photo, info in mountain lion shows a different file size than Photoshop does. I've tested with CS3 and CS6 and get the same problem. Doesn't happen with CS3 and OSX10.4 or any previous versions of Photoshop and OSX. Anyone know why?

Hi - for any photo, info in mountain lion shows a different file size than Photoshop does. I've tested with both CS3 and CS6 on 10.8.2 and get the same problem. This doesn't happen with CS3 and OSX10.4 or any previous versions of Photoshop and OSX. Anyone know why?

this one is actually a really rare symptom of a flaky connection to the ipod on a Windows PC. there's more going on in terms of hardware on nanos and 5th gens than in the earlier models ... so if the connection is flaky to precisely the right/wrong degree, itunes will see the ipod, but misidentify it as an earlier version of ipod.
tracking down the cause of the flakiness can be tricky ... as you already know ...
just checking. have you tried connecting with a different (known-good) USB cable? does that seem to have any impact on the rate of occurence of the problem?

I am running Photoshop CC 2014 on iMac OS X and have recently had to reinstall the OS following upgrade to an SSD. I cannot update Photoshop as it says it is unable to extract the downloaded files (U44M1/2010). Should I reinstall Photoshop and Bridge from scratch or is there an easier way?@@ !

Sounds like you transferred programs from another drive? This isn't a very good way to do it. Yes, re-install the Adobe apps.

Difference in file size between EM Export and Export using cmd.....

Hi ,
I use the following command in a command prompt to export a schema....
C:\oracle\product\10.2.0\database10g\BIN\exp.exe system/*****@local FILE=C:\FILES.DMP ROWS=Y OWNER=USER_DB LOG=C:\TEST.LOG
which produces a file around 900KB.
When i exported on the same database , the same dataschema , both the data and the db objects ... using the EM the file produced was around 4000KB.....
Why is this difference.....????
I noticed in the log file of the exported file using EM some additional info... such as :
'estimated USER_DB.TABLE_NAME 64KB'
Can this info justify the difference in file size between the two methods..????
Note: I use OraDb 10g v.2
thanks a lot
Simon

The export done from EM is from Data Pump export.
The manual export you did is original export.
Try do a manual data pump export using expdp and compare the size.

Photoshop and Bridge CS5 does not auto rotate SOME images.

Photoshop and Bridge CS5 does not rotate SOME of my vertical images. Most other photos taken in the same time frame and with the same camera display perfectly.
Orientation is checked for display under Preferences, Metadata, Camera Data.
There also seems to be a discrepancy how Orientation is described under Metadata for those images which DO auto rotate : sometimes it is -90 (which is how I hold the camera for verticals and which displays on most verticals) and sometimes it is "normal" even when it has auto rotated the image. I do not understand this difference.
"Normal" is also used to describe the orientation of those images which DO NOT auto rotate for viewing.
The photos in questions were taken using a Nikon D-300 which is programmed to indicate the orientation of the camera and has always been programmed to do so.
I know I can manually change the orientation but we are talking about hundreds of images (I have over 10,000 photos in all; most of which display fine).
What should I be looking for to explain and correct this issue?
I appreciate anything you can do to help. Thank you.

Thanks for responding to my query. I'll check out the thumbnail size.
It is just so curious that 90% of the verticals auto rotate and the rest do not. The ones that do not rotate are even from different years (other images in those years work fine), although all taken with the same camera.

Can't get Camera Raw widow to open between Photoshop and Bridge.

Okay, so I can't get the Camera Raw editing window to open between Photoshop and Bridge on my new computer. I used Migration Assist and synced up all files from my old computer, and the Camera Raw setting still works fine on my old Laptop. And even images that I edited/adjusted in Camera raw, they automatically pop up in Camera Raw on my new computer, but images that have not been openned in Camera Raw before, don't automaticlly open in Camera Raw editing window?
How do I fix this so that all images open through Camera Raw window before in Photoshop??

What kind of file format, raw or JPEG? If JPEG then you'll need to set your Camera Raw Preferences correctly to have JPEGs open in Camera Raw.

Font sizes between Photoshop and Edge - Any Accurate conversion table?

I have been trying to make sense of the font sizes between Photoshop and Edge. It seems that the conversion tables I have found do not actually give the right numbers and I am wondering if there is a table from Adobe that would make it easy to have the right size rather than an approximation.
I prefer to use text in Edge rather than Photoshop for many different reasons one being dynamic text.
For example a font in Photoshop in a 780 x 475 image is 8pt - In Edge, according to conversion tables it should be 11 px but it is totally wrong. It needs to be closer to 30 px to be about the same.
So, Adobe Team, any documentation on that?

By the way, I have to correct the numbers but they still do not make too much sense. The artist gave me a 300 dpi file so of course the px size what wrong. After converting the file to 72 dpi, the font size happens to be 33.33 pt or 40 px which is now way too big in Edge. It looks like the size my just be the same 33.33 pt would be 33.33 px. Is this correct?

Reducing File Size in Photoshop

Hello,
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?
I am trying to avoid having to 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.
Thanks,
Scott

If you reduce the file size in Photoshop you reduce the pixel dimension of the photo which means that you throw information away - independantly if you save as JPG or as TIFF or PSD.
That means that the reduction in file size is a reduction in image quality.
If you want to print the image you need a certain resolution (dpi) for the print - typically 300 dpi.
If you want to make a print of let's say 8" x 10" at 300 dpi you need a pixel dimension of 2400 x 3000 pixels which results in a file size of roughly 22 MB (flattened file).
If you have reduced your file to 12 MB you cannot make a print of 8 x 10 at 300 dpi without upsampling first, i.e. Photoshop (or Lr) have to "invent" the missing pixels.
So reducing the file size is simply not an option - unless you use your images exclusively for the web where you don't need large file sizes.
If you edit your Raw files in Photoshop you have to live with large file sizes.
The only way to avoid that is: Do edit in Photoshop only if you absolutely cannot do it in Lr.

Two drives shows difference in file size, two drives shows difference in file size

i have two drives on 'Lacie' and other 'seagate'. Both the drives have identical data, basically they are backup drives.
File size that shows up at the bottom of finder window is different in both the drives.
They have a difference of 3kb data. Though the indivisual files on the both the drives shows the same size.
My question is why would be there any difference in file size if both the drives contains exactly the same data?

What OS version? What's the exact error? Exactly when does the error occur? What previous versions? What is on the screen when the error displays? Does Photoshop get fully open?
Try opening Photoshop holding down Shift key immediately to turn off plug-ins. Lots of good suggestions here: Photoshop: Basic Troubleshooting steps to fix most issues
