Pentax LX aperture priority, Pentax-M 28mm f2.8, about a 15minute exposure on Kodak Ektar 100 of Hoover Dam and new bypass bridge from the Arizona side parking lot.
really impressive

Did you use the lightmeter of the SLR or something else ?

Thanks!

That was shot using the LX's aperture priority mode. Funny thing was I was initially thinking of conducting star trails but forgot to take a cable release with me so going to the dam was plan B.

BTW, will an external meter be able to calculate these very long exposures? If so, how long can they calculate?

i have absolutely no idea, as i have never used a lightmeter. I know how it's suppose to work, but that's all. Hence my question

It depends on the meter. Some hand-held meters are very sensitive and can be used to calculate very long exposures in "available darkness". The Gossen Luna Pro SBC, for example, has a sensitivity range of -8 to +24 EV(100). That is 8 stops (256x) more sensitive than the meter in my K10D. To put it in more practical terms, how does 16 minutes at f/2 and ISO 100 sound?

My first SLR shots

These are a couple of my first SLR shots. I bought a Pentax SLR, with Tamron 50-200mm lens to test the waters. I took these with Kodak 160 VC Portra. The second shot, was the best I got of my boy, but I can't put one without the other.

Here's a few more from the Provia 100 roll I shot with my Canon A2e and EF 28-80 USM Mk1.

Portra comes in 160, 400 & 800 speeds.

I like the shots, especially the first.

A 9 frame (portrait orientation) stitch of the Las Vegas Airport D Gate using Kodak Ektar 100 in the Pentax LX + Pentax-M 28mm f2.8 in aperture priority mode. Same roll as the previously posted Hoover Dam shot.



Automatic stitch using MS ICE (Image Composite Editor).

The History Channel's Pawn Stars is one of my favorite shows so I had to take this shot. At night of course as it was in the high 90's during the daytime! This is years expired Fuji NPZ 800 in the Pentax LX + Pentax-M 28mm f2.8 in aperture priority mode.

True, but the meter in a LX is capable to measure from -6,5 to 25 EV....One of the most sensitive meters in a camera!

With the LX, it depends on which of the three metering systems is being used. The oft quoted -6.5 EV figure is based on accumulation metering off the film surface DURING exposure (the "working" EV range referred to in the camera manual). The shutter stays open until enough light has struck the film. The manual mode meter (used for pre-exposure metering and viewfinder display) has a more typical range of 1-19 EV.

So, if you want to know, pre-exposure, how long a low-light exposure is going to be, a sensitive off-camera meter would still be your best bet. Be aware, however, that most hand-held meters have fairly ordinary low-light sensitivity and that it is only some models that are useful in the dark.

But for these long exposures with extar 100 you should probably add some more seconds to account for the >1 stop of light loss due to reciprocity failure.
