How do you save it in jpeg?

[cbtoday]

Hi, I have a question on post processing, hope you can help me.
Normally I have a tif file after raw processing, then I load it in photoshop. I do a mode change to 16bit and RGB, and adjusted my contrast and stuff. After that I would like to save it in jpeg so that I can publish in website. BUT BUT BUT I cannot save it as jpeg, only tiff. SO I need to change it back to 8 bit, then I save it as jpeg, and I open the jpeg file I just save, the color is DIFFERENT! What is goin wrong here? Should I really need to change to 16bit before I adjust my stuff? If I do that, I can never get the same thing when I save it in jpeg on 8 bit!
What should I do?

Use the "save for web" menu selection......

Save for web destroys the exif info. Why does PS not have a save as jpg option ?

I am not sure that you need to change from 8 bit to 16 bit then back again. Fine, if you were starting with 16 bit images but yours are 8 bit. I don't think that PS can save a 16 bit image as JPEG which you seem to confirm because you are changing back to 8 bit before saving. After that, I thought that Save As offers a JPEG option which is pretty straight forward.

My next question would be why are you going to PS to adjust your "contrast and stuff" when you are using a RAW converter? I would have thought that you should get your images as you like them with exposure, contrast and saturation adjustments in the RAW processing. If you can, that is certainly the place to do it. Then save as JPEG or TIFF from your converter?

yeah, if save as web the exif info is gone.
I use photoshop for sharpening and stuff too, I find it hard to do it with rawshooter software.
Does that mean I do not need to change to 16 bits when adjusting stuff? I learnt that from the tutorials in this forum, it says better to change to 16bits before doing adjustment..

I learnt that from the tutorials in this forum, it says better to change to 16bits before doing adjustment.. I'm with Martin, "why are you going to PS to adjust your "contrast and stuff" when you are using a RAW converter?" Do it in RAW conversion before. Why does PS not have a save as jpg option ? It does. In "Save As" you have to click on the little triangle for the fly-out menu & select Jpeg.
Skips solution will do it automaticly.

You cannot save a 16 bit JPG.

There is no point in switching from a 8 bit to 16 bit, when you start with a 8.


If you stay with 8, and just Save as JPEg, Choose the Maximun Quality 12, to get the best image a retain all EXIF info.

Now i got it. The option to save as JPEG is not available as 16bit only after converting to 8bit. :)
Thanks guys I was wondering why I didn't have the option. Doh

Don't feel bad... I had the same problem for awhile before I finally looked it up in the book and figured it out.

[KevC]

Resize: Bicubic Sharper (longest length 800pix).
Convert to Profile: sRGB
Save As for Web: High Jpeg.

I don't like people peeping at my exif data =)

cbtoday - if you want to work in 16 bit, get the Raw converter to create a 16 bit file. Otherwise, you're losing information that you can't regain, and negating much of the benefit of working in 16 bit.

As others have said, JPEGs have to be 8 bit. You usually want to convert to sRGB (do not assign sRGB!) if you were working in another colour space, then convert to 8 bit, then save as JPEG. Unlike KevC, I don't mind people seeing my EXIF data.
