In 1982 the Photographers Workshop was the first privately run darkroom hire centre in the UK. We continued to offer darkrooms and tuition until about 4 years ago when demand almost dried up. Since then of course I have received regular requests for darkrooms, now I only am aware of one. Here are some details
Photochats is a community photography project offering exhibitions, photographic workshops and high quality traditional darkroom printing facilities at a reasonable price.
Black and White and Colour Darkroom Hire.
All darkroom users have to attend an induction session before using any of the facilities. This will cover health and safety, darkroom and building procedures. The induction lasts for one hour and costs £10.00.
Inductions can be arranged at any time subject to availability. Call 07921 816754. This can be extended to include a second hour of directly supervised refresher printing if requested (£20.00 including induction).
Subsequently enlarger time can be booked by the session as shown in the timetable above. There is no annual membership fee. The basic charge is £4.00 per hour to use the darkroom. Alternatively you can buy 12 hours for £35.00. These hours should be used within 3 months of purchase. All darkroom bookings should be made at least 24 hours in advance by phone: 07921 816754 or emailphotochats10@yahoo.com
