I need to upsample an 8 bit grayscale TIFF file from 2560 to 12300 px in its largest dimension. I know there is an option to do this in the Print module as well as in the Export dialogue box. However, it seems to me that sharpening and noise reduction should be done and evaluated on the image at full size--i.e., that it would be better to upsample first thing and then do all retouching, tonal adjustments, sharpening and noise reduction on the upsampled image.
Alternatively, would it be better to do all editing first, and then perform upsampling and output sharpening at the export stage? (I will not be printing, but sending a file off to print.)
In principle would it make any difference if the image were a RAW file instead of a bimap (TIFF)?
Thanks,
Kevin

You up-sample using Export dialog/command. And yes, LR does a very good job of doing this.
And yes, there is a difference using a raw, if you have that data, use it!

Thank you. I always shoot raw files with my own cameras, but unfortunately raw capture is not available with the microscope cameras I have used.

Hi,
Then which file format and type do the cameras deliver? BMP/JPEG/PNG/TIFF (8-bit or 16-bit/channel, one channel or three), BioRad, FITS, ...?
Cheers,
Bart

From what I have seen, all the Hitachi, FEI, JEOL electron microscopes save files as grayscale TIFF or JPEG. Some offer 16 bit.
