Raw to TIFF to JPEG ?

Hi guys,

Just a simple question. I convert RAW files directly to TIFF and then edit in TIFF, etc.

However, sometimes I want a simple JPEG file of the same (edited) image for use on the web, etc. When I go to "save as", it won't give me the option to save as a JPEG.

Is the only way to change that TIFF to JPEG to use "save for web" ?

Thanks Smile

Alexandra.

I believe that if your preferences are set to perform conversion from raw to tiff as a 16 bit file you will need to convert to an 8 bit file before you can save as a jpeg.
Image - mode - 8bit.

I'm glad I'm not the only one to have puzzled over converting TIFFs to JPEGs. It was quite a while before I found out that 16 bit TIFFs will not convert. Must find time to read the instructions one day Smile

Thats weird as I've never had a problem converting to 16 Bit TIFF, editing it and then converting the file I've edited to JPG??

My "normal" workflow is something like this.
1) Process RAW in Capture One (before I use Adobe RAW Plugin)
2) Convert to 16 bit full size TIFF
3) Edit Tiff in PS.
4) Save Tiff (with all the other layers) to PSD
4) Save to preview/web JPG via "Save for Web..." with Bicubic Sharper as interpolation metod.

And yes, Photoshop won't let save 16 bit TIFFs directly to JPG, unless you set the image to 8 bit mode with Save As...


I always use a technique to sharp the image before saving to small size, mainly because the JPG compression makes my images too soft, it's something like this. At least this work for me.

1) Duplicate the original layer
2) Filter> Other> High Pass to that layer
3) Image> Adjustments> Desaturate
4) Set the blending mode to Overlay
5) Adjust Opacity for better results.


Hope this help.
