Recently I have been having a problem with negative pop. My condenser enlarger (De Vere) is causing my negative to buckle smack bang in the middle of my negative (6x4.5), the area size is about the size of a penny. There is the trick of re-focusing once it has 'popped' but wouldn't that leave the area around the buckle out of focus? I could always get some anti-newton glass and fit it to my carrier but what about the dust problem? Cleaning all those surfaces would turn out to be a real pain in the... you know what.
So, is all the hassle with the glass worth it? Or do any of you guys know of any tricks that would work simply?
Oh, also I am using a 6x6 carrirer so would that leave it susceptible to pop? I might find it very hard to get a 6x4.5 carrier as they don't make my enlarger any more and this particular model is not very common.
