Product traits of shielded control cables. Product traits of shielded management cables. A shielded management cable is usually used because the connection line of electrical devices. 490's connection plug, shield control cable this meant that the digicam's publicity system would still be set for normal current gentle photography. The a hundred (and the opposite 100- by way of 300-series cameras) was designed to robotically decide flash publicity by straight measuring the sunshine reflected from the flash in the course of the exposure. Then I took a similar sequence of images utilizing the Model a hundred camera. First, I took a sequence of take a look at pictures with the Model 450 camera. I'm a bit curious as to why it was at all attainable to take an overexposed picture using the Rollei flash (in automatic mode) on the 100, but none of the pictures taken with that flash on the 450 confirmed this tendency, even when the shutter remained open after the flash fired. If you don't mind completely altering your digital camera cosmetically, I suppose you possibly can attach an accessory shoe to your camera's body (utilizing, say, small machine screws or perhaps even epoxy). In addition to needing a flash with a Pc cable, you may after all need a bracket to carry the flash, since these cameras do not have normal accessory sneakers.
So, for the subsequent check, I re-linked the Rollei flash utilizing the 'regular' Pc cable, however set the flash to full-energy (manual mode). The second take a look at, once more, used the Rollei flash and an ordinary Pc flash cable. On this case, I merely linked a regular Pc cable to the Pc outlet on the camera. So, on this case, the publicity is mounted, however the light output from the flash is variable. This photograph turned out a bit underexposed, but probably not objectionably so for most people (it additionally evidenced some gentle falloff towards the sides typical of many cheap flashes, but that's not the digital camera's fault). The third check photograph was made utilizing the Kako Mite, and this one turned out barely underexposed, but better than with the 450. As with the Rollei flash, the shutter closed instantly after/during the firing of the flash. Unlike with the 450, nonetheless, the shutter closed instantly after/during the flash's firing (the truth is, the publicity was so brief that I wondered if one thing had gone unsuitable). Given this flash's guide number, this is able to normally result in an overexposure of about 2.5 stops at f/8.8.
For the reason that shutter pace is fixed when utilizing the special flash plug, this could lead to some added flexibility when using digital flash with such cameras. Perhaps there's some minor distinction in the flash sync mechanism on these two cameras..? The two digital flashes used in this take a look at-- on the left, a Rollei 134 REB; on the best, a Kako Mite. Two very completely different digital flashes had been chosen for this experiment. While this was not a really scientific experiment by any means, I believe this little take a look at yielded some useful info. All information is offered on an 'as-is' foundation; the creator of this site just isn't liable for damages of any kind (monetary, physical, or in any other case) which might arise from the use (or misuse) of information on this site. Note: I understand that the knowledge on this web page may be confusing and tough to observe. Your experience might (and possibly will) range relying on the particular flash you use. I suppose I should be aware that Polaroid Corporation doesn't officially suggest the usage of electronic flashes with these cameras, so I'd like to emphasize that you are doing this "at your individual risk," as it had been.
While I have not examined this-- with 400-series cameras, you might be able to 'manually' regulate the flash exposure your self at the camera by changing the position of the Scene Selector and/or ASA dial to choose the lens aperture. In different words, it is best to let the flash handle the computerized publicity if potential. Test photographs were taken at a distance of 5 toes, which was chosen on account of it being a typical distance for indoor portraits, and likewise in an effort to accomodate the Kako Mite's mounted flash output (with ASA 80 film and the cameras' f/8.Eight lenses, optimum publicity should be at something round 5 feet). Film used was (outdated but nonetheless usable) Polacolor ID (Similar to Type 669) film. Ideally, A flash needs to be chosen that has an automated mode geared for about f/8.8 exposures at about ASA 80. If a guide flash is used (or an computerized flash is utilized in manual mode), then you need to keep to around the calcualted 'ultimate' distance for exposures at f/8.Eight with ASA 80 movie. But, since all the previous test photos utilizing this flash (at 5 toes from the target) evidenced underexposure, this is not too shocking from that vantage either.
