Makes complete sense, Simon, but could you say whether MGII filters can in fact be used with MGIV paper in respect of their speed matching and whether the change that came about with MGIV filters, namely the change to double exposure from grade 3 instead of 3.5 as with the older speed matched(I hope) filters is correct.
I have acquired a set of MGII filters complete and in their box, recently and believe they were used very little so fading may not be an issued.
I just want to add a couple of things, I guess to my original post. First, I never, and I mean never touch my filters with wet fingers. My darkroom has a wet side and a dry side, and never the twain doth meet. Also, I always keep my filters in the box, actually in that Rolodex type thing with the index tabs. I don't think fading is an issue, but if it was, I would have expected the lower numbered filters to have faded more since they were used more.
One interesting thing is that with the Ilford filters, the 4, 4 1/2, and 5 are noticebly lighter; they are more pink, and clearly (to me) pass more light through. Hence the lower exposure required. The Kodak filters are the opposite. The higher numbered filters are darker, and definitely require more exposure. Regarding the Ilford filters, when I used the number 4 earlier this week, I checked the actual number on the filter, just to guard against my having misfiled one or more of the filters. I checked, and it was the number 4.
So I have two possibilities. One is to experiment with the Kodak filters. The other is to buy a new set, and I have already placed a bid on eBay. And speed matching is not an issue. I always do test strips, and I at least put a quarter or eighth sheet in for a test exposure when I change filters.
So I will experiment again next week or so, and I'll report back. Thanks again for all the comments.
If the filters are coming from ebay then one can't really say they are 'new'. It would be worth buying some new ones, even a generic brand. The Kodak ones would probably do the job too.
mfohl - I have an extra set of new (never used) Ilford Multigrade (3.5"x3.5") I would be willing to give you for free. You'd just have to pay the shipping (depending on how fast you need them the shipping could be as low as ~$7 based on experience). If you want them let me know.
I've worked with a MG II filter set for about 8 years. The filters came with my most-used enlarger (Durst M800). They did a fine job with different brands and types of MG paper.
Then I read this thread earlier this year and decided to replace the MG II filters.
Well, in the grade range that I regularly use (1-2.5) the new filters work the exact same way, judged from the prints, with a not so scientific eye.
There may be a visible difference at higher grades, I have yet to try.
sandermarijn, it was you I was referring to in my post as I had spotted in a search that you had used MGII filters with later MG paper successfully as you have confirmed.
I think you are saying that your old MGII filters are in fact producing exactly the same grades as your new MGIV set? Maybe they haven't yet faded.
As I said in my above post my MGII filters seem to show little use as well but I have yet to test them
Hey Michael R, thanks for the offer. But I need the larger filters, 6 inch or 5 1/2 inch or whatever. And I have that bid on the ebay things.
Also I read the other thread, and it seems that other folks have had my experience. I'm looking forward to trying the Kodak filters.
And I hope I get outbid on my eBay filters!
Hello Folks, I did a quick test last night with a Kodak 4 1/2 filter and Oriental Seagull RC. Much better: much higher contrast. More experimenting in order, but it looks like higher contrast is within reach.
Thanks for all the suggestions.
I had pretty much the same experience with old MG Filters (10+ years old) - so tested it with my Step Wedge - and I found I got the highest contrast with G3.5, with G4, G4.5 & G5 all giving lower contrast by varying amounts.

All the steps were a bit more contrasty - but the difference was larger the higher up the contrast scale you got.
Hi, I've never not used Kodak filters - Polycontrast then Polymax - on Ilford MG and then Oriental Seagull RC papers. This covers about a 30-year period. The filters work in an entirely predictable way in providing appropriate contrast grades at predictable exposure times. Only recently it seems that my most frequently used filters are wearing out, resulting in lesser sharpness. But Kodak filters work great on most brands of VC paper.
