Truly, honestly... I haven't a clue what you're talking about.
I don't at all understand curves etc etc...
Let me know if you WANT to know this stuff, start a new thread and call it the Stone system or something like that. Like golf it's teaching someone a new grip - it can throw your game for a little bit... And I know how uncomfortable I am playing golf when my buddy tries to help me with my swing.
Truly, honestly I quit golf because of that... (I'm not saying that to be rude, I'm saying that because it is SOOOOO true).
But like pool... you'll learn to call your shots.
(snip) Enter a new to me Canon EOS-3. Wow. I can't even understand what's in the manual. Four different metering modes, plus entirely manual (which is a pain to use). I have a few rolls stacking up now, of test rolls trying to come to grips with metering. Each subsequent one a little better than the last one, but I'm still not happy. See, the meter is moody and treats flat lighting with underexposure, normal contrast with great exposure, and high contrast with underexposure.
Learning a new way of metering is painful. I have never used a spot meter, for example. Don't need to. Won't either.

Or...may be even simpler one like D-23. Just two chemicals and one film.
Thomas,
what I take away from this is: simple is good. Sometimes one needs to take the whole roundtrip to figure that out. I know I did.
The golf analogy is good, but to prove your point I will tell you with an example how I have had to change my approach. For as long as I can remember I have used very simple cameras without autofocus and auto exposure. I have used a Gossen Luna Pro for a looong time now, and am used to it. Sometimes I didn't even use a meter, and just went by experience. Leica M2, Pentax KX (has meter, yes I know), pinhole, Hasselblad 500 system, Crown Graphic, 5x7 Century, etc etc etc.
My exposures have been extremely consistent, and I know exactly how to rate the films, and how to adjust for varying lighting conditions.

I got the EOS-3 because my eyes don't focus well in low light anymore. I need freaking bifocals. The EOS-3 focusing system is amazing, and is what I need for portraits. I HAD to do that in order to continue with portraiture and do it well.
Most of all I'm glad we're having such a good time discussing HP5+ and D76.
The EOS system is easy... If you like "spot metering" make the camera metering the "single dot" in the menu window at the top (no brackets or anything just the center dot) and move the focus point to the center dot. Now meter JUST as you would using a spot meter...
That's probably best for you as you are used to spot.
Any more and PM me for assistance, if there's one thing I know pretty well it's EOS cameras...
Stone:
Your "Stone" system is perfectly fine, and very well suited to shooting with transparencies.
It's only weakness, when compared to a full zone system approach, is that instead of objectively evaluating the shadows, mid-tones and highlights of your scene, you are objectively evaluating mid-tones and (somewhat) subjectively evaluating the shadows and highlights.
This is fine if you aren't too concerned with what part of the shadows falls into detail free black (clear on the negative), or what part of the highlights goes totally white (clear on the transparency).
Where it matters, is when you want to avoid those two extremes.
Bill Burk's curve analysis helps you with the clear negative problem, because the "speed" point" is what determines how much light the film needs to make sure there is some detail in those shadows. That is how the "speed" of film is determined. When that is tested under ISO specified conditions, the ISO speed is the result.
People use different settings (Exposure Indices, or "EI") when they meter because:
1) their equipment and procedures vary from the ISO standard; and
2) they have preferences as to how they want the results to appear, and find that using different settings give them a result they like better.
If you have a contrasty subject and want a look with really detailed shadows, where the highlight detail doesn't matter so much, you can most likely achieve that by taking a reading from the shadowed area and (effectively) using an EI that is lower than the "standard". By doing that, you are placing the shadows higher on that curve, but also shoving the mid-tones and highlights up higher as well.
Now, if you want to avoid the mid-tones and highlights going too far up the curve, so as to avoid squishing them together, you can reduce the development a bit, and they will be better behaved.
If you do all that, you will have done something like a N-1 zone system pull. You will have flattened the curve.
Conversely, if you start with a low contrast scene and photograph it straight, you will end up with a curve that is too flat - the shadows and mid-tones and highlights will be all squeezed together. To stretch them out, you need the curve to get steeper. You meter the shadows, set your exposure for them, and then increase the development in order to make the mid-tones and highlights more dense on the film. In the print, the contrast will be greater, and everything will look better.
If you do all that, you will have done something like a N+1 zone system push. You will have steepened the curve.
Try to get past the fact that the curves come from numbers. Instead, think of the curves as pictures of how the film is responding to light and development. When you get the pictures the right shape, your negatives will be doing what you want from them.
And the "right" curve shape is the one that appeals to you, or matches what you want to do with that particular photograph.
My sense from what I have seen from your uploads is that you tend to prefer slightly short, fairly steep curves. Whereas I tend to prefer a longer, less steep curve.
As an example, the card I sent you came from a negative that is slightly "steeper" than I generally prefer, so I printed it a bit darker than I would print something more typical for me.
Ha... You're a funny guy. I have never used a spot meter in my entire life. Always a Gossen Luna Pro with a dome.
I agree the EOS is 'easy', but it doesn't work like what I'm used to. I have to try to figure out how the EOS works, so that I can anticipate how to manually compensate when I shoot into the light, or in low contrast situations.
My test rolls are getting better and better, but if it doesn't get better I might ping you. Thank you for offering.
I read the Film Developing Cookbook and followed forums discussions. I avoided chasing film and developers into dead ends. Nothing wrong with using a general purpose developer, D-76/XTOL, and one special purpose developer for a different look. D-76/XTOL gives consistent results. For most photography a general purpose developer matched with just two films is all you need. However, I can see using pyro with MF and LF in special light situations. I picked Rodinal for my second developer for limited situations. Keep it simple.
I can see using more than one film is appealing. In addition to HP5+ I need something slower for pinhole, so I do use Pan-F+ too. But I don't need more than D76 developer wise. I find I get much more variation by changing how I use that one developer than I get from switching to another product..
Thomas, Kodak Tech Pubs indicate XTOL is a tad better than D-76. Plus, dilute XTOL at 1:3 is close to Rodinal. D-76 is very close in quality to XTOL and if using MF will see even less difference. Bottom line is keep it simple and though
Y know what you can do with a film/developer/paper combo. Not enough time to chase after magic bullets.
I agree with all of what you say, except 'better' is totally subjective. I actually like D76 better than Xtol, for no reason I can technically quantify.
Yeah, both D76 and Xtol get really sharp at 1:3. Especially Xtol.
...I'm pretty happy with the developers I use now and don't feel like I'm lacking anything, so why?
I am new here and new to film developing--so please excuse over-simplifications. It's taken me almost two years to push through 75 rolls.
About developers: you do have to make decisions from the get go. I decided for D-76 over XTOL--even though I bought XTOL first. I didn't like the lab results for Tri-X in XTOL and was horrified to read stories of sudden death syndrome . . . so I never used it when I started developing on my own. I went right to D-76.
What I got out of that first experience through exchanges at another forum, was that the choice of developer does hinge a lot on the film you use: thus Tri-X and D-76; Fomapan 100/APX 100 and Rodinal, etc. You get different "looks"--to which different lenses also contribute. For example, a lower contrast lens with T-MAX 100: now what would be the best developer for that combo? I used D-76 1:1 and am pretty satisfied, but I think I would have been better off with Rodinal, which unfortunately has been difficult to get here in Norway the last year. (By the way, another reason for D-76, and XTOL for that matter, is that you can travel with powders in checked baggage, which means that they can be purchased in the states very inexpensively and brought back over here).
Main point: I thought conventional wisdom was that you match the film with the developer. But now what I am hearing in this thread is an all-in-one philosophy: one developer for all films. I am somewhat puzzled by this.
