How can exifer save files as *.tif files

Hi

Its barrasing to me, but true: I don`t know how to save files (with
Exifer Version 2.1.5. (Built 263)) as *.tif files. I`m sorry for this
silly question, but after printing automatically the date of exposure
into a big number of pictures (which is a tif file) exifer saves the
files not as tif but as jpeg files. How can I preselect the option
save as *.tif files in Exifer Version 2.1.5. (Built 263) ?

Can anybody help me ??

Thanks in advance

Albert
