om... Fine. That can be had by adjusting the contrast of the paper, in 95% of the cases. Most of the time, using the 'normal' grade is all that's necessary. Where the devil do you get those numbers? |

Where the devil do you get those numbers? The Kodak article I quoted from earlier suggested that film development not be changed unless.... "....a print from a normally developed negative on No.4 paper grade would contain insufficient contrast. Accordingly, in view of the desirability of reproducing most scenes with a gradient of 1.0, and because of the wide control over contrast possible with various paper grades, it is highly advisable for the professional photographer to develop the great majority of his negatives to the same gamma." In my experience, correctly exposed negatives developed 'normally' have plenty of contrast. Almost never is it necessary to go higher than grade 4. |

"Uranium Committee" wrote in message om... "Jim Phelps" wrote in message ... HUH? If things HAVE changed since 1952, human perceptual preferences are not one of them. You are so wrong on this point. AM I? I received this e-mail response from one Richard Knoppow: "While some film characteristics are rather different now the characteristics of the human eye certainly are not." [... snip ...] Two points. One: If the response of the human eye and brain were as static as you and Richard suggest, then we would still be happy smearing berries on cave walls. Two: the functional rationalization of the argument you and Richard cite presumes a virtue of _mean-attraction of tonalities_ - that's the mass-market compromise esthetic. Many of us here, and certainly those with whom you argue, are not looking for the mean compromise: they are thinking individuals who have idiosyncratic (creative, interpretive) aspirations; they are the outliers who make a difference - by definition! So, you are the Master Race, eh? Your superior 'vision' sets you apart from the inferior races of mankind. So do as you wish and strive for some kind of mass-market esthetic creed, but you will not find many sympathetic ears or eyes here. In the land of National Zonalism? You would be better served if you found an audience concerned specifically with industrial profit-driven schemas. Walmart-paradigm printing comes to mind. Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Sieg Heil! Print that in big letters and put it under your safelight. Ja wohl, mein Führer! |

Let's try it from the top: A dialogue: Photographer in sto "I'd like some grade 2 Ilford Galerie paper please." Mike: "What format are you using?" Photographer in sto "35mm" Mike: "Oh, do you use grade 2 all the time?" Photographer in sto "Uh, yeah, that's the normal grade...at least that's what I was always taught." Mike: "Didn't you know that using grade on 35mm, together with a little less development, will give you sharper, finer-grained images?" Photographer in sto "Huh? Where did you hear that?" Mike: "It's been known for a long time, in fact since the 1930's, that reduced development and harder paper gives a better print from small negatives." Photographer in sto "But won't reducing the development mess up my tones?" Mike: "Actually, no, it won't. It's only one grade, after all. Reduce the development by about 20%, maybe a little more." Photographer in sto "So, by reducing my development, what do I gain again? Won't the harder paper just increase the graininess?" Mike: "Actually, no. Although using harder paper does increase the appearance of grain compared to softer paper, the reduction in development more than offsets it. The contrast decreases less than the graininess. The net result is a better image." Photographer in sto "Do you have anything that I can refer to to verify what you're saying? It's not that I don't believe you, but you see I was always taught...." Mike: "I just happened to have this Kodak booklet here. Let's see, oh, here it is. Read this part he 'The graininess of both negatives and prints increases with increasing gradient of the material on which they are made. When the gradient of the negative material is low, prints are normally made on a paper which has a high gradient and vice versa, so what may be gained by holding one gradient down would be largely lost by the high gradient of the other. It is usually true, however, that a low gradient in the negative material and a correspondingly high gradient in the paper is more favorable than the alternative combination.' Mike: Look, here, let me show you what this will do for your prints. Photographer in sto "Wow, that IS sharp! And I don't notice any grain! I think I'll try that! Thanks, Mike!" So, you see Paul, this discussion is NOT about what effects increasing development might have on highlight contrast, however true that may be. It's about the benefits of reduced development on 35mm film. What happens with INCREASED development is of absolutely no importance whatsoever, because it causes considerable loss of image quality on 35mm film. Let's put it this way: 1. Reducing development allows sharper images because of reduced infectious development and irradiation. This is a POSITIVE benefit. This is important for the 35mm user. It is not important for the LF user. 2. Reduced development coupled with increased paper contrast should yield somewhat finer grain, and have little or no effect on the tonal distribution with most film and paper combinations. Even if were to be SOME small change from the distribution of tones achieved with increased development, the benefits outweigh that. In any event, grade 2 is no more entitled to be called 'normal' than grade 3 is. Portrait papers such as Ektalure, which were available in a single grade only, were closer to grade 3 than grade 2. See: http://www.kodak.com/global/en/profe....54.42&lc= en "Medium-speed, single-contrast (approximately printing grade 3), fiber-base, warm-tone paper. For making enlargements and contact prints with reduced illumination. Particularly suited to portraiture and to salon and display work." So, you see Paul, the reason I have an interest in your experiment is because it shows that REDUCING development and increasing contrast in the paper does not result in any loss or significant distortion of tonal balance (with the materials that you tested). Even if other materials were to show greater divergence, it does not matter, because, as I said, grade 3 is just as entitled to be considered 'normal' as grade 2. The tonal distribution obtained at grade 3 is therefore just as 'legitimate' as that of grade 2. Nothing is perfect, but obtaining the best results from our materials calls for modifying our technique to suit the medium being employed. In other words, 35mm has its own rules that are different from LF. It just so happens that reducing development and using grade 3 as 'normal' gives better results than using grade 2 and developing more, when we are working with roll films. |
