Large 16bit TIFFs the only storage option in CC cloud?

[Bohdan Chreptak]

I've noticed that when I edit a Lightroom CC image in Photoshop, its saved back into my cloud storage as a rather large TIFF in 16bit.  This is great for some, and entirely unnecessary for others.   Can this be changed?   Ideally, I'd love a way to go through my online storage and reduce to 8-bit files of smaller formats for many images where that level of quality is not required, and or at least the ability to choose the format and quality when saving back into CC cloud.

Thanks for your thoughts...

Before saving in PS go to the menu:

Image >> Mode

Choose 8 bits

Then press Ctrl+S (save & overwrite) followed by Crl+W (close file & send back to Lightroom)

Cmd+S & Cmd+W on Mac

Thanks Jon. 

I'd done that but had not been patient enough to see the change take effect online. 

I assume the only way to reduce the image's footprint further would be to 'save as' jpeg and upload as a separate file?

Thanks again!

Yes that's about it. It's not quite as neat as the imported jpeg won't be stacked with the original.

Before changing to 8-bit mode, you should go to a smaller colorspace first. The default is prophotoRGB in Photoshop for the 16-bit files that came from Edit in Photoshop. So you need to first convert to adobeRGB or sRGB. If you don't, you risk generating visible banding/posterization in your images

Thanks!  I shall keep my eye on that.
