Both Soho Images www.sohoimages.com and Film & Photo www.film-photo.com offer 16mm B/W Negative processing in London. Brian

You could try 7203 B/W Pos although it will probalby been rather high contrast. You could also try 7366 F G duplicating positive if you can lay your hands on some. It is worth trying any B/W stock including B/W Dupe negative stock 7234. I assume you are processing the reversal yourself. The stock numbers I have quoted are acetate, you can, of course, use the poyester equivalents - whatever you can get hold of. Brian

If the film is black then it can either have been unexposed in the camera or the first developer has not worked. You need to look and see if you can see any edge printing saying 'Orwo' or there should be clear areas where you laced the film in the camera. if you have no edge printing then the first developer has not worked. If you do have edge printing then the film was not exposed in the camera. The film being black means that it has been correctly re-exposed and re-developed. Brian

I have a copy of the NP55 datasheet. It is a panchromatic negative stock; the speed is ISO 80 and it recomends developing to an average gradient of 0.65 by developing for about 6 mins in ORWO developer 17. There is no mention of processing as a reversal but conversely it does not say it cannot be done. I have worked in labs doing B/W Reversal processing and it is not usually a problem to reversal process a B/W neg stock. If I remember correctly you get a slight increase in speed when reversal processing a negative stock of around 1/2 a stop. You do not mention what the problem is with the reversal exposure. It is important to give sufficient exposure for it to work correctly; you would have to give a very high exposure for there to be any problem with too much exposure. Brian

Hello Andres 72161 is Fuji 16mm Panchromatic Negative RP film, it has an exposure rating of 80ASA daylight and 64ASA to Tungsten. Although I have no experience with pushing this film, I would not think that there is any problem with doing so. The datasheet says that it is for normal or high temperature processing. Brian

Martin The Digital work was carried out at The Digital Film Lab (of Copenhagen) in their London facility. You can find some information on their website http://www.digitalfilmlab.com/ under Shorts and Features - Bloody Sunday. I was working there shortly after this work was done; I believe that the film was shot on Super 16mm Eastman Color Negative however I am sure an enquiry to DFL would give you the information you require. Brian

There have been a number of labs in UK/Europe carrying out tinting and toning in recent years. Prestech in the UK has been producing tinted and toned prints recently; Soho Images did some work about 5 years ago. there is a lab in Rome that did some work on the NFTVA's restoration of 'Piccadilly'. The NFTVA has also done some work themselves in the last 5 years. There is information on tinting and toning on my website at: http://www.brianpritchard.com/Tinting.htm Mnay archives and archive labs have produced sinulations of tinting and toning on colour stock by pre-flashing and colouring images.

Probably one of the few things you could do with B/W processing is to partially solarise the negative by exposing the film during developing. It is not very easy to do; you have to get the exposure correct. I remember a long time ago I worked in a lab where we had a small window that could be uncovered in the developer lid so that we could control the exposure. I think we used various filters to vary the exposure. Like all methods which affect the quality of the image you should think carefully before making irreversible changes to your valuable negative. You can do the same with colour negative, provided you could persuade the lab to do it for you, at your risk of course, taking heed of the above warning. Brian

Hello karl A normal Greyscale chart as used for colour film would be fine. You need to make sure that you get a range of density from white to black and that you can see all the steps of the wedge. I would have thought that if the film had been refridgerated then it should be in excellent condition. It might be sufficient just to shoot a short length of picture and include a fleshtone in it and make sure the density of the face is not too light or too dark. Brian

Motion Picture film stock does not have an expiry date on it. If you process a short length, Kodak stock will have a date code on it which will tell you when it was manufactured. You can find information on date codes on the Kodak website.Neither a date code or an expiry date is of much help to you. You need to determine the fog level of the film and its speed. These will depend on the storage history of the film. You need to process a short length of unexposed film and also do an exposure test using the normal development time and temperature. You can then make any adjustments for the film. If the fog level is too high than it is preferable not to use the film although you can try an anti foggant. In the days when features were regularly shot on B/W film every batch of film would be sent to a lab before shooting to have gamma tests made so that the lab knew how to process the film to get the correct gamma and to get the exact speed.

Film and Photo, 13 Colville Road, London W3 - 02078 992 0037 Film Lab North 96 Kirkstall Road, Leeds - 0113 2228333 Soho Images Meard St London W1 - 0207 437 0831 All will process 200ft of Colour Negative - you need to check for a minimum charge before sending your film. Brian Sorry, typing error. The number for Film and Photo is 0208 992 0037 Oh dear I am having a bad day. I meant to say 'will process 100ft of Col Neg,' but do check for a minium charge. Brian

Unfortunately Film Lab North do not process reversal; they provide a high quality service in Eastman Colour Neg processing and printing in both 16mm and 35mm. Film and Photo are the only lab offering a reversal (E6) process in the UK. They can process 16mm and 35mm. Brian

Soho Images: www.sohoimages.com and Film & Photo: www.film.photo.com can both process 16mm B/W Negative in the UK. Brian

You can get around the case of a tape system that does not permit 00 by using light 1, covering the hole with tape and duplicating the tape. Very time consuming if you have lots of lights to change! Brian

Actually there is a 00 setting on Model C's. It is sometimes known as a zero close. I know because I have used it on many occasions. Brian

You can achieve the same effect, and some times a better effect, by printing. Unfortunately it is much more expensive as you have to pay lab costs. You put three sync marks on your film on adjacent frames and ask the lab to print the film three times using red, green and blue exposures; using the first sync mark for red, second for green and the last for blue. If the grading for your film was 23 24 27 (on a Model C printer) then they would print it 23 00 00 for red, 00 24 00 for green and 27 for blue. I used this effect many years ago for a film that we were printing of ballet dancers. By moving the sync marks further apart you can change the effect ,particularly if the object are moving fast. You are welcome to contact me off-list if you need further information. Brian

Changing the shutter angle changes the exposure time of each frame and therefore enables the production of a fade out or fade in. If the aperture is adjusted to compensate for the reduced shutter angle it will produce a sharper image by reducing the motion blur and will enhance the strobe effect. The effect will depend on the speed of motion of the objects being photographed. Brian
