Fotokemika multigrade filters

I prefer the filters that go in the drawer, not necessarily because they are less expensive. A slightly dirty or slightly damaged filter above the lens will probably work fine. Below the lens, it might not. That said, I have both types and I can see no image degradation when using below the lens filters. The inexpensive set of filters from Fotokemika is better than nothing. You give up a bit of flexibility for a very attractive price, but you can make it work.

 

In the days of graded papers you needed to manipulate your processing to produce half grades. These days Ilford and Kodak give you half grades in filters and both my VC heads on my enlargers give me quarter grades. Perhaps we have been spoilt by choice. I agree with Frank that above the lens filters are less problematic when it comes to blemishes. However if you are using more than one filter in succession when making your print you will have to give then enlarger time to settle after switching filters. There is also slightly more chance of knocking the negative out of register when chaning filters.

 

Thats right. For example, you may make a print at grade 3 but may want to burn the sky in at grade 1. You would make your overall exposure with the grade 3 filter and then swap to grade 1 for the burning in.

 

Yes, there is a lot of information on split-grade printing both here and on other places. I'm not telling you to start with split-grade printing, but there is something to learn if you read a bit about it.
Most people do "ordinary" printing (instead of split-grade), but if you know some basics about split-grade, it's easier to do "tricks" like the one Adrian mentions.
