Why are Image Export Sizes Doubled when using Save vs. SaveForWeb&Devices?

Hi Folks
Maybe I'm missing something here ...
I have 2 versions of an action I use to batch process images. One uses the Save As dialogue and the other uses SaveForWeb&Devices. However, the image sizes created using the latter are about 50% smaller than those created with the former. The two actions differ only in the Save step - I duplicated the original and swapped the save step in the action.
Is SaveForWeb&Devices usign a more efficient optimisation algorithm or am I missing something?
The reason for using the Save As dialog is that Batch Processing is able to override the save location, whereas I had trouble overriding save location in a batch process which used an Action that Saved using SaveForWeb&Devices.
Cheers
Richard
P.S. I also find this size doubling takes place when using the Image Processing script supplied with PS. I'm on PS5 on OSX10.6.8.

SfW throws out redundant custom data, when the normal JPEG save does not. Using the normal save e.g. also retains clipping paths (10 years ago people used that al lthe time for print stuff) and of course also more info on color management, user metadata and what have you. Therfe may bne more specific optimizations in SfW, but that's something Mr. Cox can probably answer better...

Why is image file size increasing when changed to CMYK?

When converting the colour of a Jpeg to CMYK in Photoshop CS5 the file size is increasing.
The original image is 352KB and after saving as CMYK it is 2.1MB
Why is this happening and how can I stop it?
I'm using a lot of images for a print project so need to keep file sizes small with resolution of 300dpi. The image dimensions are really small, only about 30mm high so they shouldn't be this large a file size
I am using a clipping path but this doesn't seem to be effecting file size (I checked by saving it as RGB with a clipping path which stayed small, and by saving one without a clipping path in CMYK which was huge)
Thanks

Two things may be happening:
1)      you may be making the file pixel dimensions (width and height) larger due to the 300 dpi requirement.
2)      CMYK files, with 4 colors per pixel, are expected to be larger than JPG files, which are 3 colors per pixel and the data is compressed in a way that throws away information.
You will not get CMYK files anywhere near as small as JPG files, as you are finding.   If there are compression options available when you save the file, perhaps those can make the files smaller.
What pixel dimensions is the original JPG and what pixel dimensions are the CYMK files?

Why are java windows showing transparency when using the Aero Peak Themes in windows 7 home premium

I'm using Windows 7 home premium version. When I choose an "Aero Theme" selected from Control Panel/All Control Panel Items/Personalization, Java windows become transparent. I.E. the java content showing with the widows desktop image showing also. When choosing a regular theme, the java window is normal. The problem does not occur when running Firefox in "safe mode".

Why are all my paths disappearing when I save some files as jpegs?

I have 2 identical PSD files. Both have 10 different paths that are identical for each file. When I flatten and save one file as a jpeg the paths stay in the file just fine as is usually the case. When I open the jpeg the paths are still there as they should be.
When I save the other file as a jpeg all the paths are there after I've saved the file and BEFORE I've closed the file. After closing and reopening the file the paths are all gone. If I save the same file as a tiff the paths all stay as usual.
I've never seen this happen in almost 20 years of using Photoshop.
Anybody have any ideas?
Thank you

I am NOT using "save jpeg for web" just to be clear.
If I were, then the other image wouldn't be keeping any of its paths either.
I am using "Jpeg" in the Save As dialogue box.
If I edit the jpeg that lost its paths after opening it and hit "Save" it gives me the compression options dialogue box. Other jpegs just "save" when I hit save, I've never had a jpeg give me that dialogue box before when hitting just "Save".
If, after opening the image that lost its paths, I paste a path into that image and hit "Save"(using one of the same original paths from the same original psd file), it gives me the compression dialogue box. If I complete the "Save" and reopen the image, voila, the path I pasted into it is still there, and, if I edit the image and hit "Save" it becomes normal again and saves without showing the compression options dialogue box.

There really is no reason for this to happen. There are no differences in the images except for the content of the image and the file names.
I have tried new file names and still the same result.
I have tried working from the Desktop and still the same result.
This is a serious bug.

Color shift (lightening) when using "Save for Web & Devices..."

Can someone please let me know why I'm getting a color shift (the entire image lightens noticably) when I export an image or animated gif with "Save for Web & Devices...". It happens on PCs and Macs, and with both CS3 and CS2.
I've been using this feature (flawlessly until a few months ago) long enough to realize that there are several settings to adjust the color table, dithering, web snap, etc., but adjusting these settings don't seem to fix the problem. When I use "Save As..." the color shift doesn't occur, and that's been my workaround, but I'm currently trying to save a few animated gifs, which must be saved with "Save for Web & Devices..." in order to retain the animation.
Please help!! Many thanks.

Ah ha! I thought so. The only reason I can speak on this topic at all is because of what I was forced to learn when I started using a Dell LCD flatscreen.
As mentioned earlier, most monitors are pretty close to sRGB, which made web work somewhat easier. However, it seems recently some so-called "wide gamut" monitors have come to market, including the recent crop of Dells. The new Dells can produce a gamut that is closer to Adobe RGB than sRGB. This means -- speaking loosely -- it can produce brighter and more saturated colours than an "sRGB" type monitor.
RGB numbers, in the context of a defined colour space, represent an "actual" real life colour. A very bright red in sRGB colour space may be represented by r255b0g0, but that same "actual" red colour is represented in the wider Adobe RGB colour space by r219b0g0. Adobe RGB, being wider than sRGB, can include still brighter reds than sRGB's brightest red, hence where sRGB hits a roof at r255, Adobe RGB can keep going higher.
Imagine two ladders, each with ten steps on it. The Adobe RGB ladder is taller than the sRGB ladder, even though they both have ten steps. The 9th step is higher (i.e. brighter) on the Adobe RGB ladder than on the sRGB ladder. So if an image contains the RGB values of r219b0g0, well if you assign it to sRGB, it will not be a very bright red. If you assign it to Adobe RGB, it will be a brighter red, because that "ladder step" (like the 9th step) is higher than the same step in sRGB.
This is why your image appears brighter when viewed in SFW and in web browsers. Photoshop knows it's supposed to be using sRGB colour space, but SFW and web browsers DOESN'T, and so it just assigns your monitor colour space, which with these Dell monitors is wider than sRGB.
I think the Dell monitor is fine...I still highly recommend purchasing some type of hardware calibration utitily (one that has a thingy that attaches to the screen to measure the light being emitted). Properly calibrate and profile your monitor, trust what you see in Photoshop, convert to sRGB for web images, and forget the rest. Either way, your images will look "good" on some people's monitors and "bad" on others.

Why are the buttons faded out (cant use them) on mobile device details?

Good Afternoon
I am having a little trouble figuring out why the buttons are faded (cant use them) on the: User Mailbox -> Mailbox features -> Mobile Device Details. Any help would be appreciated. Thanks.

Hi Andy
This option is greyed out only for one user or its for all users ?
Do you have any MDM in place for managing the active sync devices ?
Have you tried disabling this feature through Powershell ?

For the Receipts app I chose to export the info as a PDF file..an email was requested..I entered info and clicked send. For the Business Card app I chose Send, not Print..an email was requested..I entered info and clicked send. I haven't received anything, not even in my spam folder.

I've just started using the App Tabs. I think this feature could be handy but why are the sites not updated when I start Firefox. Now I have to manually update the site which is somewhat of a downer. Does any of you know where I'm going wrong?

To answer the post title FireFox save all downloads automatically in the download folder, which you can find in the Documents folder. If you want to choose where to save your downloads go to tools>options>check always ask me where to save files.
Secondly, I am assuming you have IE 8 installed as this is the only version that supports this fix that is currently not in beta. Go to control panel>internet options>advanced tab and reset the settings at the bottom. This may or may not fix the problem but it is a good first step.

Why are images being copied from a linked library that aren't modified

I'm trying out the linked library feature and that is my preffered way of using iPhoto but I notice that many images that haven't been modified in iPhoto are being copied as full res modified images. My camera Nikon D2x supports auto rotation of verticle images which keeps me from having to manualy rotate these images. I understand that when I modify an image using iPhoto's tools that a full res image will be copied into a modified folder but why are images that have simply been tagged in camera as needing rotation being copied as well. Vertical images account for at least half of all images I shoot and diplaying them properly should be a look at exif or other metadata and applying rotation but since they are images straight from camera they shouldn't show as modified. Anyone have experience or suggestions on how to avoid having auto rotated images show as modified?

blinden:
Welcome to the Apple Discussions. I ran into that but in a different way. I had all of my image files in folders on a second HD and used another application to manage them. I decided to use iPhoto's alias method to work with the same files. I got a lot of files that were copied over as modified. Have no idea why. I ended up doing global revert to Original several times, watching the Modified folder via the Finder, until it became empty. I then closed iPhoto, dragged the Modified folder to the trash and then launched iPhoto with the Command+Option keys depressed and rebuild the library using the first three options. That worked and got me a pristine library.
I had not figured out why that happened. I've had the auto-rotate turned off for about a year now. Had I know what was causing it I could have checked to see if all of those bogus modified files occurred before I had turned off that option in the camera. I'm guessing now that that's what I would have found. Thanks for the info.

How stop PS6 from removing the DPI value from an image when using "save for the web"?

How stop PS6 from removing the DPI-value from an image when using "save for the web"?
Example:
- Open a tif image, that contains a dpi value (resolution).
- Use the splice tool in PS6.
- Export the slices with "Save for web", as gif-files.
Then the dpi value is removed, the gif files has no dpi value (it's empty).
How can we stop PS6 from removing the dpi value when using "save for web"?
OR:
When using the slice tool, how can we save the sliced pieces without PS removing the dpi value?

you can make your art go a little bit over the bounds. or you can make sure your artboart and art edges align to pixels

My photos are sharp but become soft when used in and IDVD slide show.

My photos are sharp but become soft when used in and IDVD slide show. How can I prevent this from happining??

Hi,
I suggest that you try unchecking both of the crop options - landscape & portrait.
To re-create your situation, I had to check the crop for landscape pictures option.
I prefer to have control over any cropping so I tend to crop each image first before creating the slide show.

Why are images on page blinking after the OSX 10.9.3 update

Why are images on page blinking after OSX 10.9.3 update on 5/21/14?

I have finally been able to get the strobe effect stopped. I've restarted at least 7 times and each time I got the light grey screen with the darker grey apple and the spinning wheel, but not the log in box I used to get before the 5/21/14 update. But I called my son and he did some research and told me to hold down the Shift key and type in my password, even if it didn't appear in the log in box. It worked and the log in box appeared and I was able to type in my password. After doing this for each of the 7 times, on my last attempt it appears the strobe effect has been weeded out. Thank God - I thought I was going blind with it affecting every screen I was on.
I hope this will be of help to someone.

All folders on my iMac are in alphabetical order, however, when I save an item to a folder they are not. Why?

All folders on my iMac are in alphabetical order, however, when I save an item to a folder they are not. Why?

Thanks for helping BDAqua
No it doesn't.
If I go to that folder afterwards, it is all in alphabetical order.
If I am working in Quickbooks, Mail or QuarkXpress and go to a folder from those programs the folder is out of order and I waste a lot of time
searching through the folder looking for what I want. This never used to be a problem until the last couple of months.

Why can't a new folder be created within my user home directory when using 'Save As' in Mountain Lion?

Hi,
So I want to create a new folder within my main user home directory (not the root directory) just for my developer-related files? I can do this from Finder, although it does prompt me for my password to do so. However, when using 'Save As' from any app, the 'New Folder' button is greyed out when I select my user home directory. So I have to create the folder in Finder then Save As.
Is this normal behavior? Is OSX discouraging me from adding things to my user home directory by making it less convenient? Is there a good reason it would be discouraging me from creating new folders there? If not, is there a setting that I can change to allow the creation of new folders from the Save As prompt?
Thanks for your help,
B

You may need to rebuild permissions on your user account. To do this,boot to your Recovery partition (holding down the Command and R keys while booting) and open Terminal from the Utilities menu. In Terminal, type: ‘resetpassword’ (without the ’s), hit return, and select the admin user. You are not going to reset your password. Click on the icon for your Macs hard drive at the top. From the drop down below it select the user account which is having issues. At the bottom of the window, you'll see an area labeled Restore Home Directory Permissions and ACLs. Click the reset button there. The process takes a few minutes. When complete, restart.
