I’m new to Adobe Photoshop – just purchased CS3 Extended. I’m working with images. When I create a new image and go to "save as", it won’t give me the option to save as a jpeg file.

Is it a 16 bit file? if so, you can switch it to 8 bit under image -mode. you do know jpeg is a lossy format?
Robin,
To save a JPEG copy without modifying your original image just use "File > Save for Web" command
SimplePhotoshop.com <

Also, if the file has layers (eg text) it will have to be flattened to save as a JPG (losing the ability to edit later).
By the way, Save for Web does not modify the original image, other than the introduction of compression artefacts, but it does remove some data from the file.
It modifies it if it’s a CMYK file, because it converts to RGB.
By the way, if I have a layered file (in CS) I have no trouble choosing JPG with Save As. The resultant file will be flattened for me. So, unless something has changed in CS3 I suspect it’s 16 bit, or there is something else going on with Robin’s computer.
Thanks so much for all the quick replies.
It is RGB – created in 32 bits. I assumed this would give me more color depth for the image?
What I did was create an image (layered) that I selected and copied merged(flattened). I put two of this image on an 8.5 x 11 canvas, so there are two layers on this new canvas. There isn’t any text.
I’m not changing or discarding the original psd. I just need to make this new image 8.5 x 11 at 150 res for printing. I know jpeg is a lossy format 🙂 There are reasons for making it so (but thanks for the heads up – not everyone knows that:)
"Save for Web" is grayed out and not available under File.
Ah ha…changing to an 8 bit image first gives me the option to save as a jpeg. THANK YOU! But why is this so??????????????
Thank you all for your help!!
why is this so?
Because the JPG file format does not support more than 8 Bits/Channel.
Hmmm….and the software does not convert to 8-bit as well as flatten…thus not offering the option?
Thanks…I will have to remember this. 🙂
Does it have to be a jpeg? Tiff might be a better choice for print if you can use that. What printing process?
Yes Ed, it does have to be a jpeg. I’m making it for a company who will sell it as a "printable". This is the format they prefer.
Takes up less disk space, the printable is great quality (thanks to Photoshop), and yet is not reproduceable as competition with the original art. I’m guessing these are the reasons.
I used PSP since version 4 and until recently saw only the similarity in function (as well as lower price). I tried the Photoshop CS2 demo and immediately saw the difference in the quality of the end product.
So I’m learning Photoshop on the fly so that I can meet deadlines 🙂
I truly appreciate your help!

if you use file> save for web (and devices now, i think) instead of file> save or file> save as, it WILL auto-flatten your image and you can save it out under a new name as a jpg, gif or png. when you get out of the sfw dialog, you then save your unflattened full feature version as a psd or tiff or something for later editing.
hth, dave
a’course, maybe i should read the whole thread before i post!

Nah, then the rest of us would have to as well.
thanks for understanding!
s’aright Dave. We make allowances 😉
8 bit image … [snip … why is this so?
There are currently no devices that can print at more than 8 bit. Some printer drivers might look as if they are accepting a 16 bit file but in reality it is being converted to 8 bit "on the fly". Personally I prefer Photoshop to be in charge of that sort of thing, rather than some printer driver.
I’d love to get an IPF5000, but they retail here in Australia for nearly $4000.00 – can’t justify that for a hobby …
