Long exposure is an old trick that one sees often. The results always have this "wow" effect and the first question that always pops in your head is “how long was this exposure?” The LC-A+ (also applies to the LC-A) has the edge for low-light photography because of its light metering. But in this case, one has to "deceive" the light meter.
I think everybody knows this trick. To get your long exposures with the LC-A+ or LC-A, just simply cover the light meter window with your finger, or if you plan to shoot in "quasi" bulb-mode, cover it with a masking tape or scotch tape; then using a marker, write over the area of the light meter window. Check how opaque it is but pointing the camera towards a bright light, half click the shutter release button and check if the right LED or slow shutter light glows red.
If you don't have a tripod, put your camera over a table, a metal railing or any stable object. Using a shutter cable release is helpful but not necessary. The question remains, how long should your exposure be? My standard exposure time is 5 seconds and with this, you get the following results:
The shots above would otherwise have ended up underexposed and grainy if I didn't expose it for 5 seconds. Sometimes, depending on how much light there is, I go as long as 15 seconds at the most. The results are close to overexposed:
The light metering of the LC-A+ is excellent but at times you have to go "manual" and add of few more seconds (5-15 seconds) of exposure time using this simple trick to get better and more interesting results.
