Re: [Texascavers] Digital (cave) Photography
A lot of the fun/pain of digital photography for many people is
interface dominated. The same is true for film cameras with
computerized controls. If the interface of that really nice camera
doesn't jive with the way you think, or controls you use all the time
are buried in layers of menues to it takes 45 seconds to take a picture
all the time, you'll get mad. Make sure you actually use the camera as
much as you can, or at least cameras in the same series made by the same
manufacturer, so you can get some idea of how it really works for you.
If you take a lot of pictures, you'll need a big hard drive.
There's some kind of WYSIWYG (What you see is what you get) problem with
Nikon that some caused some rather serious photographers I know to each
abandon several thousand dollars of Nikon lenses and start over
completely with Canon when they went digital. I don't remember exactly
what it was but it involved using a CCD in the camera that was the wrong
size (or something like that) so that although the pre-digital lenses
and digital cameras were mechanically compatible and billed as such,
that the images were not produced correctly in the image plane, or the
image in the viewfinder was not the same in the screen or photo, or
there was distortion because the chip picked up the non-rectified part
of the image from the lens, or something like that. A friend of mine
just bought a rather expensive digital version of a Nikon lens for his
non-Nikon camera that uses Nikon lenses. I don't know what this is
really all about but if you have Nikon lenses you want to use with the
D200, look before you leap.
The speed of throughput from digital camera to posted image on the
Internet or printed image (via photo retailer or your own printer) is
staggeringly fast compared to film.
All of my TCR images were taken with a $450 Canon SD850 that fits in my
pocket. I can't imagine what I could do if I had the money to spend on
a digital camera that actually had parts.

RE: [Texascavers] Digital (cave) Photography
Your TCR pictures looked great to me, Gregg. Please look for them and a SLEW of more photos from TCR by a cadre of talented cavers and photographers in a special edition TEXAS CAVER, coming to your mail box in early December. If you don't want to miss out on this issue, there's still time to join the TSA! Go to http://www.cavetexas.org/TSA/join.html immediately, if not sooner to rectify this.

[Texascavers] Canon has less sensor noise at higher ISO Re: [Texascavers] Digital (cave) Photography
Scott, Check out dpreview.com and robgalbraith.com. www.dpreview.com/reviews/canoneos40d/page23.asp * Canon has less sensor noise at high ISO. * Canon has more IS, image stabilized, lenses available. * Canon has more of the big glass. Witness how many white lenses are on the cameras at sporting events. * To be fair, most of the photographers at a weekend photo workshop I was just at were shooting with Nikon. I would say avoid the Digital Camera lenses that can only be used on small sensor, 1.6x magnification, cameras, unless you really need a 10mm, 16mm actual, wide angle lens. Watch the ads from the big electronic retailers. I just got a Canon 40D kit with the IS 28-135 lens for ~$1250 from Circuit City, $ off plus a 10% discount plus 12 months same as cash. If you really want a compact camera for point and shoot cave photos then look at the Canon G9. It now has RAW mode, 4096 exposure levels vs. 256 exposure levels in JPEG (12 bit RAW vs 8 bit images for JPG). There are times when a 30D or a 40D is too much of a tank and it is really nice to have the G9 in a jacket pocket or cave pack. Also you can get the G9 converted to take visible, IR and UV photos, www.maxmax.com/powershot_g9.htm. According to their guy doing the conversions, the G9 is his recommended PS to convert at this time. Although they will convert a number of PS and DSLR models. nigelDo not meddle in the affairs of dragons because you are crunchy and taste good with Dinosaur barbecue sauce. - Visit our website: http://texascavers.com To unsubscribe, e-mail: texascavers-unsubscr...@texascavers.com For additional commands, e-mail: texascavers-h...@texascavers.com
Re: [Texascavers] Canon has less sensor noise at higher ISO Re: [Texascavers] Digital (cave) Photography
I'd like to throw my opinion in on this subject - I think low sensor noise is even MORE important than density. (i.e. high number of pixels) It seems to be frequently left out of specifications and 8 megapixels ain't jack if they're noisy! I have a reasonable Leica lensed Panasonic camera which takes good rich, sharp images but when called on to use higher resolution than 1200 x 1600 - grainyness comes into play and 2400 x 3200 pixels isn't much of an improvement. Ideally, I figure you could extract full frame images from a tiny section of a wide field 6400 x 9600 pixel image (virtual digital zoom) but it doesnt seem like it works like that - and digital zoom itself (at least in my camera) seems horribly grainy and worse at higher ISO. -WaV On Nov 15, 2007 10:00 AM, Nigel Dyson-Hudson n...@cavesar.com wrote: Scott, Check out dpreview.com and robgalbraith.com. www.dpreview.com/reviews/canoneos40d/page23.asp * Canon has less sensor noise at high ISO. * Canon has more IS, image stabilized, lenses available. * Canon has more of the big glass.

[Texascavers] Digital (cave) Photography
Since the current topic is (Cave) Photography
I'm finally upgrading/updating my camera setup from film to digital.
I've used Canon/Pentax/Nikon 35mm SLR gear for many years...and I'm in the
middle of the learning curve about Digital SLR cameras.
I've almost decided on the Nikon D200.
Does anyone out there have any feedback/suggestions as I make the leap into the

RE: [Texascavers] Digital (cave) Photography
Last summer I bought myself a Canon PowerShot A630. Don't know how it is in
caves since I don't cave any more, but it's great for outdoor and indoor shots
and has a lot of bells and whistles which will take me some time to, if not
master, at least get the hang of. Cost on sale less than $300.
