Dave is correct on this.
Also, you might contact your Ilford rep for they have an excellent and
thorough booklet on the creation of masks.
Simply put, if you place a sheet of translucent (not transparent) Mylar
between your slide and the T-Max 100 film . . . FOR 35 MM . . . you will
obtain the needed soft and out-of-focus quality needed for the small
negative. W/6x7 and larger, you may not need the Mylar separation.
Exposure
If you have already made a good print but it's full of contrast and you
realize you need the mask, stop down 3 stops and use the same filter pack
and exposure.
Develop
Using HC-110 @ dilution F develop for 3-4 minutes and fix as normal.
Mounting
Place the out-of-focus, low contrast negative ABOVE your slide and align
carefully. It is handy to retain a little bit of your sprocket holes so you
can line up the mask w/your slide with greater ease. Affix to the slide
w/slide mounting tape.
masks can become much more complicated than this but using this combo and
method provides very good results and will sufficiently reduce contrast
particularly for Ilfochrome printing.
