Hi,

I am currently trying myself in doing some things in photoshop. I export 16 bit tiff out of lightroom, do some adjustments save it and then get a file which is larger than 100mb.

Is that normal?

How do you handle these large file sizes?

And one more question...

Does the editing i do on that tiff file saved in lightroom with lightroom has the same effect than if i would do it on the raw file? Or is for instance the change of whitle balance not possible anymore, like in a jpg?

Thanks guys !
