Save as preference does not allow tiff with jpeg compression in PScc

[Bob6647]

On my old PS CS5, I could set up my file preference to save as a tiff file with jpeg compression which will produce a file around 12-40 MB each automatically all I had to do was hit enter every time. But with cc, I have to 1.save as, 2.add the suffix letter, 3.click jpeg compression, 4.IBM PC, 5.then enter, that's 5 steps I used to do with one in CS5, Now I have been waiting for several years since cc was created hoping someone would fix this. The other image compression options LZW, Zip, & None produce much larger files than I want to store. Also, I wonder if this is a Lightroom issue since I am going from and to lightroom and it's prefs only allow the above options for importing back in? Is it possible to make some sort of shortcut, or do I need to go back to CS5? I have tried making an action but then it comes up with the same file name as the one I recorded with. Please surely someone else needs this too right?

You can make a new Action from Actions Menu for saving TIFF with your presets and you can make shortcut for it.
So If you need to save any document with these settings you just click the keyboard shortcut.

There are many disadvantages to this format. Why not just save JPEG?

[D Fosse]

My thoughts exactly. Why bother with the TIFF wrapper when it's just a jpeg inside anyway? Save as jpeg and be done with it...

Do you realise that jpeg compression is lossy (i.e. it permanently degrades the image) and that means that every time you reopen and resave the losses are cumulative. The other compression formats are not lossy and the entire image can be recovered every time.

There are many of us that disable compression altogether which does lead to larger files but with faster opening times. These days disk space is cheap, image loss is not.

I would also advise against using 8 bits/channel with the ProPhoto colour space (as shown in your Lightroom screenshot) - but that's another issue.

Thanks, davescm I did not know that about the lossy. I guess you're saying I need to just bite the bullet and stop trying to make such small images, right? Same issue with the 8 bit/channel ProPhoto colour space, right? 

Thanks for your reply

Thank you for your reply; "There are many disadvantages to this format.
Why not just save JPEG?"

What are the many disadvantages? I thought to save as Tiff you retained
more information in the image. Is that not correct?

Jpeg compression is lossy. The process of compressing the image  throws away image information. That's fine for a final copy to be posted on the web but not for a master file which might be reopened , edited and saved again. The other 3 options are "None" , which does not compress at all, and LZW and ZIP which are both lossless i.e no information is thrown away - it can all be recovered when the image is decompressed.

That's precisely why using jpeg compression defeats the whole purpose. Then all you have is a jpeg, inside a TIFF wrapper.

Thanks everyone for your replies on compression and their meanings. I tried it the way you suggested and the sizes went up tremendously as follows. So I’m wondering which you would use and why? Most everyone directed me away from using jpeg compression, but totally ignored or maybe did not understand my original question? I still have to go through all the same steps as with jpeg compression, so no one has actually answered my question as to why PSCC took away this setup preference for saving faster. It used to revert to the same procedure as last time, not anymore?

Raw file before edit              = 51.5 MB

Tiff with jpeg comp. 8 bits    = 16.9 MB

Tiff with LZW comp. 8 bits    = 35.4 MB

Tiff with LZW comp. 16 bits  = 62.8 MB

Tiff with ZIP comp. 8 bits      = 30.8 MB

Tiff with ZIP comp. 16 bits    = 49.3  MB

Tiff with None comp. 8 bits   = 51.6  MB

Tiff with None comp. 16 bits = 103  MB

Is there a way I can get an answer from Adobe, or are they just allowing questions the community?

Thanks Bobby

8 bits is not recommended at all, if you intend to do further edits. Some years ago 8 bits was all we had, but the world moves forward luckily. The TIFF compression algorithms are old and written for 8 bit data. They do not work well with 16 bit data and can even increase file size under some circumstances.

Bottom line - you really should stop worrying about file sizes. A photographer simply cannot afford to worry about file sizes, it compromises the work. When you need more space, you get a bigger drive, that's all.

[davescm]

You asked what we do.

I keep all raw files along with the sidecar file from Lightroom/ACR.

Any images that have been edited in Photoshop I save the master as a PSD/PSB with all layers in full 16 bits per channel with no compresssion (compression disabled in Preferences).   The TIFF equivalent would be the 16 bit with no compression.  Yes the files can be large, but these days, disk storage space is cheap.
