SECRETARY`S NOTES
The centre four pages of this issue of the Newsletter are another supplement for your handbook. Thanks due to our Chairman for the original script for the handbook notes.
Have you ever had problems with filters and lens hoods? A decade ago it was easy. Down to the local photographic shop and a quick exchange of hard earned cash saw a skylight filter and a lens hood on your camera.
Trouble came when wide angle and long range zoom lenses were introduced. If you fit a hood to cover the telephoto end of the lens then you will get vigenetting (corners cut off) when you use the wide angle part of the lens. If you fit a wide angle hood then it looks very silly at the long end of the lens.
One answer is to use the Cokin Multi Rubber Hood. This telescopes and folds back to give four different types of shade. For some reason Hoya plan to discontinue it! SRB Film Service have made protests over this. I hope they are successful in their efforts.
Another solution is to use the Cokin P type modular hood and filter holder. It is square and can be built up in units to whatever length you require. It works but looks ungainly. One good point with that system is that with the right lens adaptors you can switch the system from one lens to another.
Scotch Colour film has a UV filter layer on top of the other emulsions so there is little need for a sepArate filter. All modern lenses have also been corrected to cope with UV rays.
There is still a use for the Skylight type of filter when you wish to warm up a cold subject, and when distant scenes are hazy. But if you use yours to protect the lens, try a lens hood, its stronger.
Lots of interest was shown at Didcot at comparable displays of Konica and Scotch Chrome transparencies, and in the AV show of slides taken on Scotch Chrome film. The slides were all processed in the two handbook formulae, the Konica in the Moorhouse and the Scotch in the E6/7.
Last week Tony Chuter of Area 17 sent along 48 slides. Again they were Konica and Scotch 100 ISO. They had all been processed together in the same E6/7 handbook formula brew. The slides were absolutely first class and if they had been given to me in a random order I would have been unable to tell which type was which. Perhaps the Scotch product had a slight edge, but it should have as it costs £43 for 18 cassettes of Scotch and £26 for the same number of bulk loaded Konica. Meanwhile in the shops Fuji is now over £48 so we must be on a winner.
