How can we ignore the B-mode failure of our LC-A +? Here I show you how to do long exposures with your LC-A + using only one finger.
One of the limitations of the “new” LC-A + is the lack of bulb mode (B) and it is present in the original LC-A. The LC-A + is fully automatic and choose the aperture and exposure time “appropriate” for the lighting conditions at the time of shooting. This is enough for most situations but not when we need extra exposure time for taking pictures at night. For example, when we are faced with a dimly lit scene, but a strong light source nearby fools the light metering of our camera.
Most photometers must know that the LC-A + is in a nearby window to the wheel to select the ISO. When we change from ISO 100 to ISO 200 (or higher) also makes a small mask with a hole in the center in front of the photometer. The higher the ISO the greater the hole allowing more light reaching the photometer and decreasing the exposure time. This is connected with the least amount of light they need fast film (high ISO) to be well exposed compared with slow film (low ISO).
Now for the trick: We must take into account all the usual recommendations for night photography (tripod, cable release, slow film, etc) but before pressing the shutter button, we have to place a finger to block the light from entering the photometer. We keep two fingers in this position (blocking the photometer and squeezing the trigger) for a time deem necessary for our photo. Then, remove the blockage of the photometer and camera shutter closes automatically.
