what am I doing wrong with TIFFs?

Howard here is the file you put on You Send It run through PS CS4 with my post action.

Save at a quality of ten (10) it's under 200K.

And it may be me.

 

I'm absolutely certain I handled all the files the same way, and it was only with the TIFFs, and repeatedly with the TIFFs, trying at different times with different files over the course of a month or more, that I couldn't reduce the size as I could beginning with other originals. Of course, "absolute certainty" dies hard.

 

Hey Howard!

 

LOL!! I know what's happened here, and it's happened to me as well, so I wanted to make sure you were doing what I thought you were doing and, well, yup, you're doing it.

 

 

Ready?

 

You've embedded the C1 camera profile in the JPEG, and it's large When you create the JPEG, the profile stays intact (and large).

 

If you convert to a normal display profile (like sRGB--what I'd do for the Web anyway) or strip the profile out, then your JPEGs compress easily and quickly.

 

In sRGB, for example, your small JPEG file is 35KB after saving. That's more like it, no?

 

So in a way, you're right: since C1 lets you embed their input profile and other programs don't, it would only be in C1 TIFFs that you would see the problem.

 

Hope this helps!

Jamie, Jamie, Jamie! Bless you!

 

I knew if anyone could figure it out, it would be you. I had thought that I might be embedding the RWL correction instructions, but that didn't make sense since they're already expressed.

 

 

So let me ask one more: Where do I turn off "save camera profile" in C1?

 

Thanks again!

 

 

 

FYI, Ed sent me his PS actions set; I haven't had a chance to look at it yet, but I think he's saying, "The only way to get this guy to go do something productive is to send him something I know works!" Ed, thanks for the offer and the fulfillment. I'll try to stay quiet for a couple days.

Howard, you're welcome. This has stymied me in the past, but in PS, not from C1.

 

So here's where you want to think about your "workflow."

 

Do you want to make JPEGs straight out of C1? Or are you trying to make them in PS?

 

Either way, you can do the same thing two different ways...

• You can output a TIFF or JPEG directly from C1 in sRGB. Go to your output options and create an output with that profile. If you're in C1 v4.x Pro, you can name an output style and associate the profile you want with the output tab. That way, when you want JPEGs, you just select that output and presto...
  
• You can output TIFFs the way you're doing it now, with the camera profile embedded, and then "Convert to profile" in Photoshop. In PS CS4, with Save for Web, there's actually a check box that lets you "convert to sRGB".... though you can just do the conversion (from the Edit menu) and then resize to your heart's content.

Either way, without the larger input profile attached, the resulting JPEG will be smaller.

 

BTW--the smallest JPEGs have no profile attached at all; that's an option on both Save for Web and Save As... JPEG in Photoshop. Note that you should convert to sRGB first, and that colour-aware browsers won't have a profile to apply, but for speed and portability of graphics that's the best way to do it.

Bravo! Thanks again, Jamie!
