Hey guys, I've owned this enlarger for sometime, and I got it brand new in the box with the manuals and all the documents. However, after using it for about 6+ months.. I'm having a hard time trying to figure out where to place the filters. I bought some Ilford filters- not the ones in the carrier, but just the sleeves (if that makes sense). If anyone has experience with this enlarger, any help would be great. Also, I've searched around on the internet and couldn't find anything. There is no recognizable filter placement on the enlarger- Do people just hold it under the lens?
