Didn't make it to rehearsal -- no ride, which is just as well since this headache hasn't gone away. Tincture of basil helped but not enough and not for long.

I offloaded the pics from the digital camera from yesterday, and every damned frame came out almost entirely black, whether it was shot in shade or sunlight, with or without flash, and regardless of exposure compensation dialed in. WTF? (This camera tends to underexpose night shots, but not this much, and not usually in daylight.) I started tweaking them in GIMP with the levels tool (the histograms were all piled up in the leftmost quarter of the graph in each frame), but then backed out and ran the whole directory through ImageMagick's 'convert' program and told it to equalize every file. The adjusted versions are at least bright enough for the thumbnails to be useful when picking which of the 97 frames to look at more closely; many wound up unuseably grainy after equalization, but some aren't too bad and a few of the grainy ones might be salvageable if I go back to the dark originals and try adjusting them by hand ... or not.

I do not understand what would make the camera screw up like that on every frame. But I'm glad I shot four rolls of film as well as the digital shots. (Er ... that'd be about 110 frames give or take a few, depending on which rolls I got an extra shot on: 24 B&W, 36 Kodachrome, 36 colour print, 16 medium-format slide (I gambled on shooting a roll of Velvia in the Holga).) But I've gotten used to how quickly I have a file to work with from the digicam, so I'm feeling impatient about seeing what's on the film. I don't quite have the energy to go develop the black-and-white tonight, but maybe I should grab a few other rolls and the changing bag and start loading up reels and devloping tanks in case I feel up to pulling out the chemicals tomorrow. The colour pring and slide film will probably have to wait until I have a car again and run up to Charles Village where the lab I go to is.

[Later edit, since if two people in a row misread this entry the same way, maybe I wasn't as clear as I thought I was in the second paragraph: the extremely dark pictures were the 97 from the digital camera. I haven't seen any of the film yet, but I said I was glad I'd shot film as well because I'm counting on that to come back with fewer surprises ... when I finally manage to get it developed. I used four different film cameras, so if one of those glitched as well, I should still have usable pics from the other three.]

Off the top of my head. when I did that stunt, I had the wrong f-stop for the film.

The camra's battary or film being old or there being something wrong with the lense could also be a reason

If your developing the film, is the "Darkroom" dark enough? Did any light get in to over expose the film? Were the chemicals at the right temp and not over used?

Way too many questions.

Er ... I haven't seen any of the results from the film I shot yet -- the nearly-black images were from the digital camera (a point-and-shoot where I've got an exposure compensation setting but no other controls that affect exposure other than the choice of whether to use flash.

I just tried a flash picture and it looks okay on the LCD screen; I'll try in daylight tomorrow.

Is it possible that the film's too old? I had that happen on the last 'real' roll of film I shot, a few years ago -- and that was shots that I really needed to have look good, as they were for selling jewelry.

If you get some of it scanned in or online somehow and want to send it to me, I can play with it in Color It! (think Photoshop for those without much money) and see if I can make it clearer.

Not possible with the frames in question -- the glitched ones were from the digital camera; I'm counting on the film, which I haven't seen yet, to come out better.

I've had that happen with my little cheap HP digital. Usually it turns out that it's gotten confused by a patch of light in a corner of the frame. Apparently, it really does try to average the light level across the entire frame...

The spouse & son have much nicer Olympus digitals that can do spot metering in addition to averaging, so they rarely run into that problem. Since I mostly shoot pictures of fencing bouts (and awards pictures), I'm always running into "issues" with not enough light, no flash allowed, and rapidly moving white-clad figures... The want^H^H^H^Hmust have list for my next digital (still or video) is getting fairly specific (and probably expensive).

Hmm, that's weird about the digital camera. I haven't seen that before (with either camera), but I'm hardly a pro.

I presume it's not that you somehow had some wacky levels set in the customization menus? (I think those would reset on a power-cycle.)

The exposure compensation setting persists across power-off / power-on, but I'm pretty sure it gets reset after a battery change or a memory card swap. And I used at least two different settings during that day (and changed batteries partway through).

Equally mysterious, it worked fine for the test shots I did yesterday to try to figure this out.

Maybe the green man doesn't like digital cameras, or this camera doesn't like him? Let's see whether it works normally at the Faerie Festival on Saturday ...
