As much as I regretted missing Balticon (all the more so knowing that Urban Tapestry was performing), I did have stuff to distract myself with at home over the weekend. A new toy uh, extremely important new used piece of equipment that will extend my capabilities in one of my crafts. Okay, that description applies to the near future; over the weekend it was Fun New Toy. And of course I really had to play with it in order to learn how to get the most out of it (not that the lack of such an excuse would have made any difference). Thanks to the kindness of another person on a mailing list I'm on, who made a very nice offer and a time frame for payment that I ought to actually be able to manage, I've finally got a DSLR.

So as a side effect of spending so much time playing ah, experimenting with the camera, I've spent a lot of time in GIMP the last few days, tweaking what I've shot. And finding out which of my odd ideas confuse the camera, and trying to figure out how to de-confuse it when I want to do those things. (Like using a pinhole lens.)

Using the DSLR feels very different from using the digital point&shoot. Not only because it has more controls and different features, but because it feels so much more familiar since most of the film I've shot has been done using SLRs. It does have a "PHD" mode ("push here, dummy") of course, and fancy modes beyond any of my film cameras (mostly -- with one exception -- due solely to the age of my film cameras, not the fact that they use film) ... I don't know of anybody marketing a fully manual digital camera, so I don't think there's a digital equivalent of the legendary K1000 ... but one thing I've already noticed is that instead of making my old manual-camera skills obsolete, this system just makes applying those skills faster and easier.

Despite the limitations of the p&s and the increased versatility of the DSLR, there are a couple of things that a point&shoot or rangefinder-style digital camera does more conveniently: two that come to mind are using the LCD instead of the viewfinder when putting one's eye to the viewfinder would be geometrically challenging or uncomfortable, and using the LCD as a viewfinder that can be artificially brightened via the exposure-compensation setting, in poor light. (The p&s is also smaller and lighter.) In an SLR the mirror blocks the sensor until the shutter button is pressed, so it can't use the sensor and the LCD to preview a shot, only to review a shot already taken. (Presumably this could be done when mirror lock-up is used, I suppose -- do any DSLRs do it that way? The camera would have to close the shutter and drain the charge on the sensor before firing, I guess, but I don't know what major obstacles there might be.)

In addition to playing with pinholes and macro, I spent a while hunting dirt bikes and birds. Catching birds in flight with a long lens (but not really birdwatching length, just long by normal standards) is a lower-stress activity when I know I can just zap the missed shots and messed-up shots and reclaim the space, instead of each near-miss costing me a frame of film. But I'm going to need a lot more practice with birds before the next time that I try going after bats. I'm not sure what the small birds in Baltimore that move in not-quite-bat-like ways are. (That is, they're gobbling insects out of the air, AFAICT, which means they're solving the same problem insectovore bats are, though anatomical differences result in flight path differences.) I'm guessing they're swifts, assuming Baltimore has swifts, 'cause swallows have a more distinctive tail, don't they? There are a few other species visible along -- or over -- my street as well. The robins make short, low-altitude flights across the street and back, not staying in the air long enough for me to get them; pigeons mostly make short flights like that too, but they're slower and sometimes fly above rooftop height, so they're easier. The others mostly stay up where they're silhouetted against the sky -- once in a while I manage to catch one with the underside of its wing illuminated by the setting sun.

Any of y'all good at identifying birds from their silhouettes?

Memorial Day Weekend Birds 2008

( 1024x1024 version @ Flickr)

That covers much of my weekend. But other things happened as well:

B brought over a scavenged rackmount computer. Unlike the other rackmount computer I've got, the graphics card in this one gets along nicely with Ubuntu Linux. Two older machines are starting to fail, so migration will be a double win (the more stuff I stuff into the rack, the more floor/desk space I get back).

And when I got stabbed in the back with eight of these... a claw
... I decided it was time to wield these: claw scissors

And finally, links to a few more of the photos I shot over the weekend:

Most of these photos (all but the claw scissors) are in my Flickr 'photostream', along with a few I didn't list here.

At least one DSLR has a mirror-up live sensor mode, but a bunch now have tiny video cameras in the optics path in front of the mirror to drive the LCD with. And at least one has a hinged LCD that can be used for overhead and waist level shots.

Aha! On the ones with a tiny video camera, does the video camera swing up out of the way when the mirror does?

Hinging the LCD like that is, I think, an obvious step once you can use it for preview/composing. I've seen how useful a feature it is when watching folks with non-SLR digital cameras use it. (My p&s doesn't have that feature; the LCD is fixed in place.)

In the design I can remember, the vid pickup lives up inside the pentaprism, so it doesn't have to move. It of course does have mirror blackout.

Which DSLR did you get? And unrelatedly, are you planning to go to Baitcon?

a) Pentax *ist-D -- which means I can use all my old lenses on it (some more easily than others; I lose some useful metering info with pre-A lenses because Pentax left out the aperture simulator lever on this body). I used a Super-Takumar that's about as old as I am, on a screwmount bellows attached to an M43-K adaptor, to shoot the 2mm buds that will eventually become grapes (http://dglenn.livejournal.com/1138797.html). (Of course, none of my wides are digital-sensor superwides, but I reach teles more often than wides anyhow, so I can live with that for a while I think.) Now if I manage to find an FA 50mm, that'd be nifty (none of my primes are autofocus).

b) I would very much like to go to Baitcon. I'll change that to "planning to go" once I've ascertained that I can actually get there.

I wish my Samsung P&S digital had a viewfinder in addition to the LCD--it's damn near impossible to use outside on sunny days. (I'm considering a flip-up hood that Ritz Camera sells, or making a hood/shield of my own to allow me to see the LCD under bright light. (My Nikon CoolPix 3100 has both LCD and optical viewfinders, and you can turn off the LCD viewfinder to conserve battery.)

My wife has a Nikon D70 and a D200, both of which are dSLRs with standard viewfinders and LCD review. (By definition, the Reflex precludes using the LCD as a viewfinder, I would think.) However, there are manufacturers who make 45-degree mirror lens adapters, allowing you to shoot off to the side without pointing the camera in that direction..

Pentax calls the thingie that attaches to the eyepiece and has a 90° bend a "refconverter". I've used one, and it makes lining up a shot with the camera on the ground much, much easier. (I don't currently have one. I had one but it got stolen -- and I'm not sure whether it would've fit this camera or not anyhow.) But the ones I've seen are still "put your eye up to this" devices, not for holding the camera overhead or at waist level.

Pentax did make a waist-level finder for the 67II (medium format SLR), but that had the advantage of starting out with a 6cm X 7cm focussing screen, mirror, etc. (I know waist-level viewfinders exist on other MF cameras as well.) If you know about something that amounts to a waist-level viewfinder for 35mm or DSLR cameras, that'd be something I'd enjoy knowing about.

(Y'know, as much fun as the *ist-D is, I still dream of getting a 67II someday. 6x7 slides are cool.)

Now I'm visualizing a google-attached fiber optic or RF viewfinder extension... :)

My psychics (or at least my bird-watching main squeeze and her bird-spotting book) suggest that the third from the top on the right edge is likely a Chimney Swift. The big center one and the one on the bottom right are doves of some sort.

The two on the left of the bottom edge and the second up from the bottom right corner appear to be herons of some sort (seagulls generally have wider tails and a less thick neck, but the stills' angles could be deceptive).

The two on the right side of the top edge are pigeons.

I don't know of anybody marketing a fully manual digital camera
Casio QV-3500EX camera (from DCResource) Canon PowerShot S1 IS camera (from DPReview) Panasonic DMC-FZ18S: Lumix 8.1-Megapix DigiCam w/ 18x Optical Zoom, 28mm Wide-Angle LEICA Lens, 2.5" Diag LCD
All of my (non-SLR, so far) digital cameras have allowed manual operation, along with full auto (with various "scene" modes) and aperture or shutter priority. (You can specify that in most of the on-line camera-finder-for-you shopping guides.) They've also allowed manual focus, but (for all 3) that's been very cumbersome, and it wasn't really possible to judge focus with the the viewfinder or the screen. (The first had an optical viewfinder, and the other have 2 electronic.)

Mine allows full manual control, but I don't know of any that, like the K1000 -- favourite of photography instructors for so long -- is solely manual. (And finding one would surprise me. Though it would be perversely cool.)

Nice thing about an DSLR (compensation for all that extra weight I'm carrying compared to your pleasantly featherwight camera): manual focus works just fine. (OTOH, I have to change lenses twice to cover your camera's entire zoom range.)

Pentax K1000 SLR camera (from Louis Villafranca)I didn't remember that the K1000 was purely manual. (Mine was stolen many years ago.) I haven't seen a retro digicam like that either.

Part of the manual focusing problem is the typical digicam's user interface, particularly on smaller cameras. It's all switches; they work OK for selecting from menus and making adjustments in steps, but they are inadequate for fine, continuous control. Very few have something as efficient and effective as a ring around the lens barrel.
