How to create clipping paths in JPG image?

1326 views16 repliesLast post: 9/18/2009
I have seen some images claim to have "clipping paths" (from which I assume they mean a mask path) yet the image is a JPG file.

How is that done, and how can it be used?

I don't think it can be done. But in many cases you can get away with a file that looks like a JPG outside (name in *.JPG) but is actually something else inside, using a format which supports clipping (GIF or PNG), by just renaming a .GIF/.PNG to .JPG (but why would one do that?).

See http://www.bigstockphoto.com/core.php?showpage=help_clipping paths

Just what I was looking for -- thx!

Now a strange turn though -- My Photoshop CS4 does not have JPG as an option for saving. I have been doing that conversion in Lightroom.

1) I wonder if saving as PSD and having Lightroom save as JPG will keep that path?

2) I wonder why the heck PS CS4 doesn't have JPG as an option? CS2 and prior versions had it... (I skipped CS3 so don't know there)

Yeah, it does. If the .jpg option does not appear, then the file has multi-layers. You must flatten before saving as a .jpg. Or, if you want to keep the multi-layered file, flatten and then "save as" a ..jpg. The multi-layered file is retained.

Burt,
I suspect you are working in 16 bit/channel mode and jpg is 8 bit. If you are shooting RAW, working in CS4 you are by default working in 16 bit and therefore do not have an option of save to jpg option.. There are several ways you can get your jpg option back. 1: After you have made all your adjustments, go to image->mode->8 bit/channel. Then you will be able to save as jpg. without changing your original 16 bit file.

or if you are not concern with 16 bit editing

2: In ACR when converting a RAW file go to the workflow options (that is the blue underlined notation which looks like a url, under the image window in ACR) double click on that. the workflow options window will open.
Here you will see the following:
"Space" for workspace where you will have options for sRGB, Adobe RGB, ProPhoto, etc.
"Depth" for Bit Depth, here is where you set the bit depth to 8 Bits/Channel.

You can also set your crop size, resolution, and if you want to open as a Smart Object.

You lost me, Savage. If you are working in 16 bit, and then convert to 8 bit, doesn't the image change from what you brought it to? You are working with fewer colors in 8 bit. I export from Lightroom to CS4, and have CS4 set to 8 bit. That way any adjustments I make in CS4 will be what I have to print or view on the web as a .jpg. I know I can print as a .psd or .tiff, but once the image leaves Lightroom I expect to be able to upload it to my photo host as I've adjusted it.

You are correct, however I was just trying to solve his proplem of the missing "save as jpg option".
It seems he has either forgotton about the 8 Bit jpg, or was blissfully unaware and believed CS4 was lacking in some way. You addressed the issue regarding layers and that may also be his problem.

I also use Lightroom which uses ProPhoto 16Bit as a default workspace. I also do as you have and export to CS4 set at 8Bit which also solves the problem. (and change to sRGB for web)

He could also make the changes in Bridge or ACR.

Just adding to the mix.

Bingo. That explains it -- thx!

For those times I need to end up with a JPG, I can do the convert to 8 bit. Just something I had not thought of. I guess I'm a little surprised the JPG conversion doesn't just cover the 8 bit conversion as part of it, along with compression settings, etc.

Use the 'Save for Web and Devices' option in the 'File' menu. Take great care to not accidentally alter your original .PSD as well. Only do the last bit when you are happy the rest is right and saved.

Also resize the image to something appropriate before saving as JPG.

Because the higher resolution modes contain more of the original color and gradient nuances,
I prefer to work is as high a resolution as possible, considering what needs to be done. I then convert to 8bit if I need a jpeg.

I'm very surprised jpegs can be saved with vector layers!

So was I, but a test proved it worked quite nicely.

JPEG's can't be saved with a vector layer, or any other layer. A path is not a layer, however. Photoshop can save paths in a JPEG.
