Default Paper Thickness

There is absolutely no difference between the thickness of MG4 and 5!

This was mentioned in my previous post some months ago to which there is a link on page one of this topic. I checked the boxes of both versions and I saw that both papers are stated to be 190 gsm, which is actually quite a lightweight paper. Then I used both a micrometer and an electronic Vernier calliper to check the actual physical thickness and both instruments indicated that the paper on both versions was .24mm thick and 4 sheets together gave .96mm.

So unless Ilford are using a base paper which is slightly more translucent there is no difference in thickness. Whatever the case MG5 is a big step forward and it works well for me.

What sort of light are you using to 'see' your fingers through? I have a 25w 6500degree Kelvin LED bulb in my darkroom as an inspection light which is far brighter than a normal tungsten bulb of that power. I found it was almost impossible to see a shadow of my fingers with the paper held 12 inches away from the bulb.
