H'mm on my computer screen there is just a slight yellow cast in Andy's one and too yellow in John's.....I guess it's what monitor you have and how you prefer the shot to look.
It's a mixer for your channels.Whats a channel mixer?
Tbh I didn't notice much of a cast until joxby posted his adjusted version, which, for me is too "warm"
Somewhere between the two versions is needed I think.

LMH-Front-Door by Andy, on FlickrWell I've got something to do..either this is the crappiest 28-80mm zoom (Nikon) ever made or the house is this crooked..OK at 28mm you'd expect the edges to go in but the centre corner of the house is bent and the bottom windows are leaning inSo I'll reshoot with some 28mm primes maybe another zoom.

I've seen some very crooked old buildings, so I can easily believe it looks like this. What did it look like through your eyes?
Given the age of the building I am not surprised that the corner lines are crooked. If you get a chance, have a look Google street view of the main street of a town called Lavenham in Suffolk and you'll see what I mean.

Another shot from the same night shoot at Kenilworth Castle as my first night shoot, taken on the other Pentax MX loaded with Vista 400. 5 seconds, the slowest of the 3 exposures I made. @steveo_mcg was right, the longer exposures blow out on the right, so I think it was brighter than the LV1 I guessed.

I've not had much experience with long exposures on colour negative so I'm not sure how well my crib sheet stands up. It really depends on the reciprocity of the film you can easily blow out the highlights while trying to get enough light for the shadows on some films. On the other hand working out what LV1 is relative to others shots is largely practice and I bet I'd mess it up more often that not now I'm out of practice.
Well someone would probably say I'm talking a load of..... for colour neg film but I've taken shots up to 45 secs without adjusting the ISO and they came out ok (maybe I was lucky)....when you think about it e.g. the Canon T90 goes to about 45 secs on auto, well you'd think a sophisticated camera would have an inbuilt repciprocity factor for long exposures if needed....if Canon never had a clue about film characteristics....then shame on them.

Nice idea but how would the camera know what film was loaded and therefore the reciprocity needed? A camera is just a box that opens the shutter for as long as it deems necessary to get an exposure using the settings you provide (over/under/0) and its' light meter.
Well the camera knows the ISO by the bar code, and if all films have a reciprocity problem then the inbuilt computer could adjust for the number of secs\mins..Ok it might not be spot on for every film made but good enough when you consider the latitude of neg film. Anyway most of my night shots over the years are under 7 secs and never had a problem.
Even if a 10 or 20 year old 35mm SLR camera could recognise RF though the DX code, it would most likely be limited to the film database programmed into the camera at the time of manufacture. If so, how many currently available 'modern/improved' film emulsions would it recognise today, bearing in mind there's no way of updating the software on the T90 (or even the EOS3, which I believe was one of the last 'electronic' pro-grade 35mm SLRs offered for sale)? It's a nice idea, but it's perhaps just as well they never did it, as it probably wouldn't be much use these days.
Well if it could read type of film in the 80s and as most modern\new film emulsions are more light sensitve esp Fuji it would just mean the neg would be more over exposed and the film's latitude could cover that...but did have a get out in saying I might be talking a load of ...![]()


That is awesome [emoji108]
If the DX code for the emulsion had changed the camera wouldn't be able to recognise it against the ones programmed into its memory, so it would probably have a hissy fit and burst into tears... in other words it would be overcome with emulsion!![]()

OK ...![]()
Presumably some films were ok to use without worrying about reciprocity up to that time limit? I could be wrong but isn't the benefit of Fuji acros 100 that it doesn't suffer from reciprocity failure? Or at least that it is unaffected up to a certain exposure time which is longer than many other films.Well it was a good idea in the 80's, but maybe there was a good reason why it was a bad idea and never programmed into the camera's computerbut still doesn't explain the cameras that can go up to 45 secs on auto (or the OM's can go up to 90 secs ?) when in theory the exposure would be wrong.
