I have a 12 MB dng file that was created by D700, 14 bits, raw. ( when I uploaed the photo I converted it from nef to dng).

When I open the file with Photoshop CS4 and just save it – without any editing – I get a tiff file of 70 mg. The file size is similar with no and LZW comeression.

I use ProPhotoRgb.

Is the size of the tiff file reasonable?

My guess is that you have saved it as a 16bit file instead of a 8bit, this will increase the file size.

I indeed saved it as a 16 bit file, because I understand that if one day I want ot print it the quality of the print will be better. Anyhow, does it exlain the big size?
