That would have been a step too far back then:laugh: His head seems to have aged quite well. And Rejlander made a better job of it than the BBC have with all their digital equipment.

I've always thought this photograph of John the Baptist illustrates the point rather well https://www.royalcollection.org.uk/collection/2906274/study-of-the-head-of-john-the-baptist-in-a-charger and the BBC falsify their photographs too. There are at least two people who have been...

LOL. So we all know you haven't read it but you are going to advise us about what it contains.

Which is not very much. So you have discarded zone 0 and zone X as though they don't exist in "The Negative". Have you ever read "The Negative" or do you just like spreading contentious and misleading information.

fogging or flare, probably in camera but could be in processing. Are results always like this or is it just one roll of film from that lab. If the latter then I would suspect its the lab who have fogged your film somehow.

I was thinking the very same thing but can't be arsed to take the time to do it. Besides, if you can't visualise it in your mind then you are always going to struggle with it anyway.

The zone system says that 1 zone = 1 Stop. However, there is some highly misleading things in the zone system and AAs "The Negative" book. Firstly if you look in his book AA shows that zone 8 typically gives a negative density of 1.3logD. Now a print at G2 uses exactly 1.3logD so for ISO...

Just to emphasize this point. If you have a high level of IR in your subject then you can get this IR blooming effect even if your film has anti-halation dyes in it. Where that dye is makes a difference too. If its on the back of the film it won't be as effective as if its between film support...

well if you adhere to what the zone system really does then yo should meter a zone 3 area and close down 2/3 of a stop to place on zone 3. And if you were placing on zone 7 then you should meter a zone 7 area and open up 3 1/3 stops. However I'm not going there and you would likely end up with...

I just find it handy to think of 1 zone = 0.7 stops so that I can think in normal zone system placement. i.e. I can look at something and say that needs to be zone or zone 7 or whatever and then convert to placement on film curve using 0.7. Otherwise when using ISO speed would zone 3 really be 2...

becasue you start from zero and goto 7 stops (its actually 7 1/3 for ISO standard but 7 is accurate enough). So thats a 7 stop range divided by 10 to give you 0.7 of stop per zone change. If you did the calibration I gave you link to, then it would 1 zone = 1 stop becasue you have halved film...

instead of using EV you just say 1 zone change is a change of 0.7 stops. So closing down two zones would be 0.7 x 2 = 1 1/2 stops. This when you are using ISO speed and manufacturers recommended dev.

yes if highlight densities are consistent then print times will be fairly consistent too. Paper can reflect 7 stops in good lighting so in theory if your subject is 7 stop range then it should print directly to paper at G2 if your film development was normal. In less than optimal lighting paper...

depends on your countries regulations on disposal of chemicals but most most of us do I think.

Now let me see, film manufacturers claim resolution of upto 200 lp/mm in relatively normal b+W film. 100-150 lp/mm being more realistic for their lab tests. These tests are done at a contrast ratio of 1000:1 which is 10 stops or so. And they use alternating black and white lines as test targets...

and so it may be but you need a lot of over exposure for that and halfing box speed and reducing development doesn't cause more than a stop and most likely only half a stop if you get it right. Now if we are claiming thats going to cause a problem then you are wasting your time using film and...

But this is due to diffraction around the edge of the rebate/frame. That should be obvious to you.

you're only getting half a stop extra exposure so you take any point on the curve and say well its getting half a stop more exposure than a point below it so it must be bad and you could say something in zone 7 is getting 4 stops more exposure than zone 3 so it must be terrible compared to zone...

and another thing. The zone system is about ensuring resulting print detail resolves where you want it to resolve. So zone 3 just has full textural detail and zone 7 is just before you start to lose highlight detail. Neither of those two desireables are compatible with under or over exposure of...

I would just like to point to everyone that it doesn't matter one iota what EI or speed you use on your meter becasue your meter doesn't expose the negative. What matters is where you place the exposure on the film curve and that depends on how you interpret your meter reading to do that. For...

expose for the shadows means take care not to underexpose your negative. That's all and there's nothing more to it than that. How you go about taking that care is a whole different barrel of worms, not least because you really don't want to underexpose your highlights either if you can possibly...

the use of the term marketplace serves to emphasise what I said. i.e. its about money and expectations before appreciation is given. End of discussion.

Does a playright have to perform his own plays to you? Does he have be the director of the production? Does an author have to read his work to you himself or print the book himself? This argument is about money and appreciation but you just haven't realised it yet. When I was a teenager I had...

My suspicion is that 6x4.5 is ideally suited to full or half length portraits and was a format favoured particularly by wedding photographers who have now nearly all gone digital. Therefore demand has dropped right off the scale which is good news for anyone wanting a 645 film camera today...

They all start developing at the same time and continue at the same pace throughout development. However, there isn't very much to develop in the shadows and so they reach completion of development(everything there is to develop has been developed to completion) before highlights do. The...

and I got it partly wrong too in post I just deleted.

Ralph, Take a look at what your signature settings actually are in your forum settings. They are clearly wrong as its showing an unbounded url tag.

But the etymology is as various as how, why and when to use a grey card (or not as the case may be):wink:

A friend who used to run a small private catering company told me that she really loved doing catering for wakes because the bereaved were always happy to let her choose the menu and organise it as she wished without interfering or being picky about anything. They were just happy that someone...

It was OPs above quote that dictated what I wrote. He's headed off down the grey card and 18% road which only leads to oblivion so I tried to stop him in his tracks. There are those who have lost all perspective and continue to search for the magic bullet in a grey card which doesn't exist and...
