Tiff file image size discrepancy

Hi All, I've created a mono, bitmapped image approx 400px square.
Then saved the file.
If I go to 'get info' (I'm on an Apple Mac), it says the file size is 97k.
If I open the file in P'shop (CS5.5) and go to 'Image Size', it says the file is 19.2k.
Anyone know why I get two different files sizes?
Many thanks, RP

I'm sure that the TIFF file and Photoshop "Image Size" are both 19 KB by coincidence. The "Image Size" is the number of bytes consumed by the uncompressed pixel data. A TIFF file has to contain a header, so the image data in the file will be compressed then the file header will be bringing the file's total size to 19 KB.
Photoshop embeds metadata in TIFF that your client most likely does not need. Use your Mac's Preview app to reduce the size of TIFF:
In Photoshop, copy the image to the clipboard.
In Preview, do "File > New from Clipboard" followed by Save with format TIFF and compression enabled.
(Do not open Photoshop-saved TIFF with Preview and then re-save, because the unnecessary info will be maintained. Use the clipboard.)

Lightroom 1.4.1: Reducing File/Image Size for Web/E-Mail

This should be a simple thing.
I need to reduce my file size to upload it into various things on the web and e-mail and what not. Sometimes it asks for a specific size.
Right now, I'm using the Export function to do this, which means I have to reset the Image Settings each time in order to get to the size required.
Isn't there and easier way to do this, like just type in the image size you want and have the program reset the image proportionately?
Is there a ratio chart for this, like 1000 x 1400 = # of bytes?
This is a function used all the time--I can't believe it's this cumbersome.

(a) How do I know I am selecting the correct pixel size for e-mail? Just keep hunting and pecking until I find the right mix or is there a number combination that works consistently? And if the latter is correct, what is that number combination.
I just can't believe that reducing the MP size to get it in shape for an e-mail "thumbprint" photo is this tough. Even with the 'preset', I'd have to set up a preset for every picture because they vary by MP and the scaling seems to change.
There is no "standard" size for sending images via email. Just make it small. There is a save for email preset in recent releases of Lr. You can download the demo and see what that entails.
You don't have to create a preset for each picture. I don't know what you would say that. Yes, the amount it compress varies with the information in the image, but this has always been the case with JPEGs. You don't have to make an image that is exactly some size. You just have to make it small enough for most MTAs and MUAs to handle. Since there is no real standard for this, just make it small enough for you.
Something like 800px on the longest side, 70-80% quality should do it to find the JPEG compression sweet-spot.

Help Needed With File/Image Size

I need a quick way to find an images _dimensions and size in kb_ on a safari webpage without having to download the image.
What I'd really like is to be able to right click on an image and have the dimensions and size in kb displayed. Either that, or use an app to do it.
Right now I am using the Inspect Element tool in the right click menu to find an images dimensions, but it doesn't show size in kb anywhere that I can see, and it's kind of a pain working with all the drop down menus.
Any help would be appreciated. Thanks!

Activity window? I'm not sure what that is.
Here's what I'm working with: http://i.imgur.com/vDwvk.jpg
Opening an image in a new window shows the image size in pixels in the tab. (circled in the screenshot)
I can see the same info using Web Inspector. (also circled in the screenshot)
*I need a way to easily see both the image size in pixels and its size in kilobytes.*
Thanks!

Image Size Discrepancy

When I try to paste an 8 x 10" photo into a new blank document, it becomes a different size. And the new size seems to be arbitrary. Sometimes it's 6 x 8, sometimes it's 8.25 x 10.5 inches. Why is this happening? It's really frustrating because it should be so simple! Here's exactly what I'm doing:
1) open 8 x 10 inch image
2) select all> ctrl c
3) create new document, set to 8.5 x 11 inches
4) ctrl v
5) my 8 x10 image is now some random size, anything besides what it should be.
Any ideas?

Its highly unlikely that its arbitrary its more likely that Photoshop is doing it properly. Your more likely using two different resolution images.

Rotate .pdf file image for Plotter printing

My .pdf file image size is 46.76" wide and 24.24" high. I'm trying to rotate and print the image on an HP plotter such that the 24.24" height is printed across the available 34" width of the plotter roll and the 46.76" image width is printed along whatever length is required as the plotter paper comes off the roll.
I've tried every combination of auto-rotate, custom paper sizes, etc. and the image always prints vertically (as displayed on the computer screen) - reducing/compressing the overall size of the printed result.
The plotter is an HP DesignJet 1055CM - I'm using Acrobat Standard 10.1.5 on Win-XP/sp3

Use what ever format you like, I perfer .tiff with LSW compression or .eps. If you don't know what you are doing just include the original image when you send you project to the printer and link the image in InDesign don't embedded it. When you furnish the original image the prepress department can set it up correctly.
I perfer 300 dpi with image is at 100% of the final size, if the image is printing 150 line screen when printed. 200 dpi is ok for 133 line screen. I would even perfer a 100 dpi image over a .jpg image that has be over compressed.

File Size Discrepancy Between Photoshop & the Finder

I'm trying to be as brief as I can, so here goes. The specific application (PS) is irrelevant, I think. This is about why an app shows one file size & the Finder shows a different file size. In this case, it's a huge difference, due to the file being an image.
I imported into PS CS, from a CD, an original image, which the Finder shows as 269.4 MB. The file format is TIFF, and the bit-depth is 16, not 8. The Finder shows it as a "TIFF Document." Now. I did a Save As and edited that as a master image file. So, I have two files: the original and the master.
I substantially cropped (deleted) pixels in the master file. So, at the same 16-bit depth, the master file should be smaller in size than the original. Right? However, the Finder shows the file to be 433.6 MB in size! Photoshop shows the file to be a more realistic 185.8 MB in size. Why is the Finder showing such a huge file size? Why is the Finder storing 247.8 MB more than I need? The Finder shows this file as an "Adobe Photoshop TIFF file," so there has been a change in format. The file is flattened; no layers, etc., are involved.
One clue could be that the Finder is storing the larger file size to accommodate Photoshop. If one multiplies 185.8 MB by 3, the result is close to the 433.6 MB figure. The 3 stands for the three color channels (red, green, blue) of each pixel (data element) in the image.
The original image, however, is stored correctly by the Finder. Photoshop and the Finder agree on the 269.4 MB file size. If the above scenario were true, the Finder would be storing the original file at three times the size as shown in Photoshop. In other words, there would be consistency in what the Finder is doing.
I suppose I could just ignore the discrepancy, but I have hundreds of images to process, and I don't want to have to go into PS every time to get a true reading of file sizes. The Finder should be accurate in doing that.
I may be in the wrong forum re: Photoshop, but here I think I can find some expertise re: the Finder, since the Finder's storing procedures are in question, to my mind. It's definitely an app/OS interface problem, as I see it. Simply, I edit a file downward in data, save it, yet the Finder saves it at a larger size.

...do you think a lot of cloning & healing brush might have added to the file size, even though I cropped the image?
Yes, depending on your History settings. The more you work on an image, the more history it accumulates. The more different states and sanpshots you save in the History palette, the bigger the file gets as you work on it, because you're storing (within the file) complete information about the file's state before and after every individual change you make to it. What I don't recall is whether that all gets saved to the file in a Save As, or whether the history is flushed each time the file is Saved.
I should warn you that I am by NO stretch of the imagination a PS expert. I was still using PS 5.0.2 until last February, when I upgraded to CS2 (knowing it will be years before I have enough hardware horsepower to run CS3). I'm a rank beginner with CS2, and if someone else wants to jump in here and point out that I'm all wrong, it will be no surprise to me. And because I never used CS, I don't know whether what I'm describing in CS2 is even relevant here.

For the Batch Sequence that "asks" --
Something to try.
Open the Batch Sequence dialog.
Select the appropriate Batch Sequence.
Click the Edit button.
In the Edit Batch Sequence - <name of sequence> dialog, use item number 3's drop-down menu.
From the menu, select 'Same folder as originals'.
"OK" out of the dialog.
Give the Batch Sequence a test run.
Output ought to be to the same folder as that of the selected & processed files.
Be well...

Tiff file size reduction

I notice that when I open a tiff file with CS6 and then close it, the size has been reduced. If I do the same thing with Microsoft Image software, the file stays the same size. Any idea why? As far as I know I am not telling Cs6 to compress the file.

Using PS CS6 with NO changes applied to the original TIFF the JPEG file size is 8.686 MB. The slightly larger file size is due to metadata differences between LR and PS.
Both Adobe applications (PS CS6 and LR 5.71) are producing near identical and much larger highest quality JPEG files. PS 12 Quality is the same as LR 100.
SUGGESTION:
1) Close LR and rename your LR Preferences file by adding the extension .OLD to it:
Mac OS X
Preferences
/Users/[user name]/Library/Preferences/com.adobe.Lightroom5.plist.OLD
Windows 7 & 8
Preferences
C:\Users\[user name]\AppData\Roaming\Adobe\Lightroom\Preferences\Lightroom 5 Preferences.agprefs.OLD
Reopen LR and it will create a new Preferences file. Try the JPEG Export again using the same settings as I have posted.
2) If still no change I suggest uninstalling LR, delete the new LR Preferences file created in step #1 above, keep the .OLD Preferences file, and reinstall LR 5.71.
3) If all is well now close LR and try restoring you original Preferences file by renaming the new Preferences file something like .OLD.OLD and removing .OLD from the original file.

Best Image File Type & Size for Photo Books?

When you select your photos to be included in a Photo Book submission, is there a required file type and maximum size. Most of my images are presently Photoshop .psd files and TIFF files of substantial size -- around 2 to 4MB, that I will have to import into iPhoto '09. Thanks.

Interesting. Presently, all my image files are at 300 dpi.
Remember that DPI has no meaning for a digital file - digital files have only dots - the per inch part comes form the print size so until you select a print size you had only "d" - not "dpi" - that is a totally meaningless number
See +The Myth of DPI+ for more information
How exactly is print size determined in the photo books -- from your selection
Obviously from your selection - you place a photo into a frame and the frame size is the size
You may want to take the tutorial for more information - http://www.apple.com/findouthow/photos/#books
or, whatever size results from the image resolution.
remember that images have no inherent size - they are just dots (pixels)
Is the ideal resolution 300 dpi? Thanks.
any image that will print at 180dpi or above will give good results (and will not get a resolution warning)

How to export the same mb size of my cr2 files into jpg or tiff files in Lr?

How to export the same mb size of my cr2 files into jpg or tiff files in Lr?
Let's say my file size is 22mb, when i export the file to tiff or jpg, although Iam careful with the settings- file size, dimension, resolution, I can't manioukate how I want it.
With jpg I tried everything, no matter what i do or change in files size or resoltion it remains the same size- 7mb as opposed to 22..
Please advise,
Best wishes,

I would noramlly opt for a tiff file, sending such a high res through the nest a nightmare
This is probably just an improper use of terminology, but the resolution of a JPG, DNG and TIF should all be the same.
The files differ in size, not resolution and not number of pixels.
Jpg is not that bad, but its a pitty they have to be edited under a jpg format..
Your raws are edited as raw. There is no loss of quality in the editing process. The files are then exported as JPG, which will cause a loss of quality. For just about any use, the loss of quality in the image when you export a JPG at quality level 12 is NOT noticeable. For many uses, exporting a JPG at a quality level of 8 will not be noticeable either, unless you intend to print the photo at a very large size. As twenty_one (not his real name) said, "Jpeg compression is fantastically effective".

Writing Adobe Image Resource Block to a Tiff file

Possible solution :
I would have to add the Image resource block data to such image in which the profile information is missing.
Problem :
I would have to write metadata for the tag 34377 as given in the Adobe Specification for the listed resource Id
How am I suppose to write this entire block and assign it to the Tag 34377 in C#?
What values should be added for each resource Id ?
Tiff Image : http://1drv.ms/NtzbCr

Bypassing the portion of the file is not a option in my case since a part
of the program reads the bytes and performs operation on the image when it
reads 8bim.
The image if re-saved in Photoshop gets the required metadata. (Can be seen
by using imagemagik's identify utility)
Only option that I have is to write the information for the resource in
side the Image resource block tag.
How am I suppose to write this resources when I am using BitmapMetadata
class?

Image size vs file size

Hello,
I would very much appreciate an answer to the follwing: 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.

The file size of the JPG on disk is 300kb this is because it is heavily compressed.
The file size shown in Photoshop is uncompressed and appears at the larger size.
Yes, compressing loses information but it may not lose much quality the first time it is compressed.
To minimise data loss use a compressed TIFF format.
Or stop worrying about file size – storage space is cheap!
The only time JPEGs should be used is for display on the web.
In fact for general use in Adobe applications, the PSD format is fine. (As long as it lasts! )

Image size on new files

I've recently purchased a new machine with windows vista and loaded on CS3 photoshop (which is new to me).
My problem is when I open a new file it's huge.
I set the size to a simple A4 and resolution 150 pixels/inch but the image size is 3.24M before I even start. I've done various tests by bringing in old images I created and they do come in at original size, it's just new files. I've gone through all the settings and everything looks normal.
I'm really stuck with this one.

Until you save there is no file size. The scratch file size used by Photoshop is not directly controllable. It includes history items, layers, etc., in addition to image data. The image data for an image that is, for example, 1000px x 1500px (i.e., ~1.5 megapixel), will be about 4.5 MB uncompressed in RGB 8 bit per channel (i.e., 24 bit) format. The same image, in an uncompressed RGB 16 bit per channel (48 bit) format, will take up about 9 MB. This is the full image data as used within Photoshop, and determines the size reflected in the Info screen (after being modified to account for history, layers, masks, etc.). When you save the file, it will likely be much smaller, unless you intentionally choose an uncompressed TIFF format. A compressed TIFF file will save considerable space if it's an 8-bit image. GIF (which allows only 256 distinct colors) is an appropriate format for very small images (such as thumbnails) and text/line art, and saves a huge amount of space. JPEG is used for the final version of photographic images, and it saves considerable space over the original due to compression, but its compression is lossy, PNG has the potential to trump many of these formats, because it can accommodate 16-bit images, allows for transparency, and it is lossless, but it is not fully compatible with some existing web browsers (i.e., IE6).

Server goes out of memory when annotating TIFF File. Help with Tiled Images

I am new to JAI and have a problem with the system going out of memory
Objective:
1)Load up a TIFF file (each approx 5- 8 MB when compressed with CCITT.6 compression)
2)Annotate image (consider it as a simple drawString with the Graphics2D object of the RenderedImage)
3)Send it to the servlet outputStream
Problem:
Server goes out of memory when 5 threads try to access it concurrently
Runtime conditions:
VM param set to -Xmx1024m
Observation
Writing the files takes a lot of time when compared to reading the files
Some more information
1)I need to do the annotating at a pre-defined specific positions on the images(ex: in the first quadrant, or may be in the second quadrant).
2)I know that using the TiledImage class its possible to load up a portion of the image and process it.
Things I need help with:
I do not know how to send the whole file back to servlet output stream after annotating a tile of the image.
If write the tiled image back to a file, or to the outputstream, it gives me only the portion of the tile I read in and watermarked, not the whole image file
I have attached the code I use when I load up the whole image
Could somebody please help with the TiledImage solution?

Why jpeg file exported from Aperture with 300 dpi's it opens with 72 dpi's on PS ( image size)? I've tried several combinations and all give different results. And I am confused on what is the best workflow for me.

Ok.
My workflow is
RAW > Aperture Library > export jpeg high resolution 300 dpi's > one file on PS > edit > Save us jpeg. The I realised that files from PS were being save in a smaller size from the ones exported form Aperture. That is when I went o see <image size> on PS and files were with 72.
Since ten I've trying different things
1. Aperture > export as PSD > open on PS > edit > Save us jpeg = small file (around 15 MB)
2. Aperture > export as jpeg high resolution 300 dpi's > open on PS > CHANGE dpi's to 300 on <image size> edit > Save us jpeg = big file (Huge, actually)
What am I doing wrong? Would someone give me guidance and tell me what is the best workflow, considering I edit photos to deliver to my clients and I shall give them 300 dpi's.
Thank you
