SLIDE COPYING By Eric Deeming LRPS and Dave Deeming LRPS BPE1 (Area 9) Having tried unsuccessfully to copy slides with a slide copier using daylight and flash we went to a M.C.P.F. seminar which included a talk by Geoff Ashworth FRPS on his method of copying slides and manipulation. It was a coincidence that an article then appeared in the C.R.C. News about his methods and the offer to purchase some of the rear projection material he used, which we took up. On a wet Sunday morning after breakfast and not being able to do any photography outside we decided to experiment with the system and chose a failed competition slide that the judge said was too small in the frame, so we set out to enlarge it using the following equipment. a) TABLE Putting the slide into the projector you focus onto the screen and obtain the required image size by moving the screen backwards and forwards on the table (a zoom lens on the projector is useful). You can fine tune with the lens on the camera. You then fit the 80a filter onto the projector with the blue tack, take an exposure reading through the camera and shoot away. You then repeat the process with the 8b filter to see the effect the 2 filters will give. You will need to experiment with your equipment to see which will give you the best results. THE DETAILS OF THE SLIDES SHOWN ARE SLIDE No. 1. ORIGINAL TAKEN AT THE KINGSBURY WATER PARK NEAR TAMWORTH.SLIDE No 2. 80A BLUE FILTER ½ SEC F4 SLIDE N. 3. 80A BLUE FILTER 1 SEC F5.6 SLIDE No. 4. 80B BLUE FILTER ½ SEC F4 SLIDE No. 5 80B BLUE FILTER 1 SEC F5.6
PROJECTOR TO SCREEN 76 INCHES COPY FILM WAS KONICA 100 ASA, WITH FULL LAMP INTENSITY. Having taken our first tentative steps with the system. We are impressed with the ease and the quality, and it our intention to attempt to do some creative work and the results we will pass on through the C.R.C. News. |
