?increased grain when using glass negative carriers?

[Chuck Pere]

Do you see a difference when looking at the grain with a grain focuser?

[Drew Wiley]

Incidence of light, manner of diffusion, presence of a specific mask or not, specific enlarger lens and its own focal length and working aperture, all play a part on how either grain or dye cloud edge acutance is rendered. This might or might not come out the same as our eyes see it through a grain focus device. Sometimes a blue filter is required to visually offset the effect of an orange mask in color neg film, or yellow-brown pyro stain, or just because our printing paper doesn't see red light. A decent test strip tells more anyway.

And AN ring issues, dust, and even glass flaws which aren't apparent visually under a magnifier tend to get accentuated when printing on more contrasty VC settings or high contrast paper. Lots of variables.

Not really. Much of the grain is especially seen in the sky + clouds.
All of these responses have been helpful so thanks to all!
