I'm zeroing in on my second 4x5. One that interests me greatly is the new Phill ips. I'm having a little difficulty deciding which back to get if I decide on t he Phillips. If I get the sring back it is a half pound lighter, but it can't b e fit with a fresnel. It can be fit with a boscreen. Dick Phillips did a littl e testing for me and basically the fresnel was equal to the boscreen at the cent er, but one to two f stops brighter at the edges. The boscreen was about one ha lf f stop brighter then the plain ground glass. Based on this I'm leaning towar ds the extra half pound and getting the international back. However, I have zer o experience with the spring back. It looks like it would be way easier to inst all and remove film holders than the international. Any comments on advantages of a spring back over the other or anything else I rambled on about here? Thank s.
