Scott The 1. 60 linesmm figure comes from Fujis own data sheet for Velvia 5. You can download it here. C. Sharon Wow, thanks for that clarification. So basically Mauro I are resolving something like half of what Fuji rates as the limiting resolution of the film for very high contrast stuffRapidshare Proposal Kit ProfessionalI can believe that. Actually, thats much more believable to me than Mauro actually achieving 9. Fujis rated resolution of the film with high contrast subjects. So in a nutshell, our calculation of the resolution of the 3. Velvia film was fine, but my calculation for the lens required for that resolution was off bc my number for Rmedium was off by a factor of 2 I shoulda been using 3. Actually, as long as were being thorough, we should be using the cyclesmm figure for the 1 2. Mauros chart actually had under his lighting, rightBut anyway, like I suggested earlier, say Velvias resolution is 1. I dont think given that its 8. Then 17. 5 cyclesmm 11. Rlens Rlens 2. Then youd only need a lens with a resolving power of 2. Mauro I see. Not a lens with 2. Dave, perhaps you shoulda read my earlier post that said exactly this. Still, I feel queasy about these numbers. Is this final interpretation correct Anyone else want to chime inThink more Creatively. Hochwertige Filzwolle im Vlies zum Nass und Trockenfilzen, Filzanleitungen, Merinowolle,Strickgarne zum Strickfilzen. Robert Actually, in Fujis data sheet above they say 1. Am I to take it that they actually mean 1. I guess Im willing to buy this bc if you extrapolate the MTF curve past the highest spatial frequency Fuji reports MTF for, a 5 MTF corresponds to about 1. MTF curve. which of course is a big assumption. That would make Fujis resolving power for high contrast subjects 1 1. Chief Keef Finally Rich Mixtape Download Sharebeast. Effective resolution of a 3. Velvia for 1 1. 00. MP. Kinda crazy, but I guess irrelevant in the real world since, like you say, MTF5. Im assuming the useful MTF, MTF5. MTF3. 0 or MTF2. 0, for any medium depends upon its rolloff at higher spatial frequencies. MTF5. 0. For Velvia, MTF5. Schaller Floyd Rose Intonation Tool. MP for a 3. 5mm frame of film. Interestingly, thats exactly the MP resolution of a full frame digital sensor that Norman Koren suggested back in like 2. Dave My math isnt wrong 1Rsystem 1Rlens 1Rmedium is well established. And Im not trying to tell anyone anything. Im just pointing out that if you use this formula, you get a ridiculous resolution requirement for the lens. Hence what I was trying to say was that something was wrong with our calculations or our interpretation. Rapidshare Proposal Kit Professional V17' title='Rapidshare Proposal Kit Professional V17' />I. I agreed with you that it seemed ridiculous to require a lens capable of resolving 2. Velvia we calculated from Mauros experiments. Youre not contributing to the discussion by just repeating you dont need a 2. Velvia film. The other guys here who posted after you are actually helping by offering a reason for why my calculation might be off.
