It has something to do with the way its reflected.

Okay, I know my camera's not a POS, but why is it that you can't do that with dSLRs? Just moving into one now, it'd be interesting to know.


Because the mirror reflects the image to the viewfinder. The sensor isn't charged or exposed until the mirror goes up and the shutter opens. This is what gives them their fast response rate (no need to flush the sensor before recording another image) and long battery life (don't have to keep the sensor charged all the time to get a live view) compared to a P&S. That and not having to extend and retract that lens all the time. :) There are a few newer dSLRs that are starting to come with live view, but it's not something you'd use all the time.

Edit: PM me if you have any more questions, just to keep this on topic.

you can with a 1Dmk3, so expect to see it on other models as they become available.

A friend of mine had a restored 1955 Ford truck. (well, partially restored) unfortunately he was having trouble finding an authentic steering wheel. So he used the largest set of vise grip pliers he had. Worked out pretty good unless you accidentally hit the release........

You should maybe use a medium format TLR. Most people won't even think that it's a camera.

I really want to get pentax 645 or something as far as actually shooting medium format.

In other news your probably right.

Yup -- when it makes economic and ecological sense. My car is a hybrid. My TV works and gets the stations I want -- why pay monthly fees for something I don't need, or through out a working piece of toxics-laden equipment?

Technology doing a circle ? :-)

Yes, a digital tuner/adapter will let you use your current TV and an antenna; since the signal is digital, reception/fidelity is not nearly as critical as with an analog TV signal. I think the Federal Government is supposed to give analog TV owners some kind of credit towards a digital tuner when broadcasters are required to go all-digital in a year or two.

yep, the off-air signals are uncompressed so their quality beats HD over satellite or cable, even better than my FiOS (fiber optic cable). I used an amplified off-air antenna for awhile but the FiOS gives me 20 HD channels plus all the HD-only subchannels (in SD).

Just keep in mind your TV has to have a built-in HD tuner or else you need to get an external HD tuner and connect it to your TV via component cables.

its not just photography, camera or TV, my daughter (she is over 3) keep asking why?? if i say we will go in the evening to buy something then she would say "why" then she will say is that for me?? :)

I always read that when kids are about 3-4 years old they have lot of questions and now I am seeing that happening :) so far she does not know that there is something called "film camera" she knows only one thing and that is digital camera.

I don't have kids to explain this stuff to, but it floors me that:

(1) I got my first computer, a TRS-80 from Radio Shack, in 1985 and it had no practical application at all; in high school, my friends paid me to type their papers because I was one of the few people they knew who had a computer - with a dot matrix printer no less; my first email address was assigned to me by the university in 1993; I taught myself HTML in PICO in 1994 before there was any such thing as an HTML editor; and in 2007 I can't imagine life without a computer.

(2) I used to have the phone numbers for all my friends memorized. In fact, I still have all those now defunct childhood phone numbers memorized. Today, I barely know my own phone number, let alone anyone else's - that's what the Contacts in my cell phone are for! I know exactly three current numbers - mine, my parents, and my employer. How many do you know without looking them up in your cell phone? Also, I remember going on a cross-country road trip in 1996 with a large bag-style car phone (remember car phones?) that plugged into my cigarette lighter. I was the only person I knew with a portable phone of any kind. It was a generational culture shock when I went back to school last year and saw that every single student had a phone to their ear while walking between classes. And I admit I feel absolutely naked without my cell now, even though I hardly ever receive any calls.

Rebecca, thats why I dont program number sin my phone till i remember them. The ones i do this with i memorize the ones i dont... then i dont know them.

I played with a few TRS-80's and even have a 1983 IBM PCjr. (Before my time but i like old stuff).

The subsequent blows to the head explain a lot.

Trouble with using medium format is that the airport security people don't understand why opening up the film packets is actually a big problem. Especially when they've just confiscated the electrical tape you use to tape the packets shut after you've shot the film, because electrical tape is a "restraint device".

A significant number of my friends and relatives are surprised that my diary is made of pulped wood wrapped in treated cow skin, and that I update it using a thin stick of carbon. "But you work in IT, you should have a PDA" they say.

I got my first computer a little later than that...a Timex-Sinclair. Then a Commodore. When I bought my first Tandy, it had a 100mg hard drive and 2meg RAM. Salesman told me I would never fill up my hard drive and that 2megs screamed! Oh... I almost forgot the 1200 baud modem that I had to plug the phone handset into to work.

My first home computer was a Texas Instruments 99-4/A ... 128 kB of memory and a cassette recorder for storage hooked up to an old color TV. It took close to a minute just to load a 50-line program back into memory. But I eventually wrote a text editor and a couple of arcade games on it.

Next was a Mac SE/30, with 1 MB of memory and a 40 MB hard drive with the 9" built-in B&W screen and a dot-matrix printer -- the whole thing cost me $4500 on a student loan and an additional 1 MB memory upgrade cost $250. I actually never filled that hard drive, and when I got my next Mac with a 1.6 GB hard drive, I swore I'd NEVER be able to fill that one (I did).

Now I have a 3 GHz dual-processor machine with 2 GB of memory and 1 TB of storage (250 GB hard drive + 250 GB external USB + 500 GB external NAS) and I can already foresee the say that it fills up. :eek:

I remember the first time we got a computer that broke into gb's of disc space....a whopping 1gb. Bad mammerjammer.
 07/23/2007 10:43:55 AM · #44
I still remember my first computer:
Pentium 75mhz
4mb RAM
500mb hard drive
4x(!!!) CD-ROM
and a blazing fast 14.4kbps modem
800x600 VGA monitor
Windows 3.1
That was all the rage back then

In comparison, my computer now...:
Intel coreduo 1.866GHz
1GB (soon to be 2GB) RAM
80gb internal drive, 80gb and 500gb external drives
16x dvd-rw drive
56k modem (I'm pretty sure this has never been used)
1920x1200 WUXGA+ monitor
Windows XP pro
And this one still sucks...

Gotta love technology.

The first computer I used had punch cards. Not fun if you dropped your tray of cards I remember

I also used to write FORTRAN on a VAX system, using dummy terminals in various locations. I remember standing on a chair at 4AM and yelling at the thing to work after having spent 3 hours looking for one small syntax error.

07/23/2007 11:12:47 AM · #46
My First PC and kinda old since i was born in 1985 lol. Was a 286 which was replaced later by a 486 DX2 66mhz which was maxed till i got my hands on a used machine powered by a Cyrix 6x86 166mhz.

Over the years ive Aquired 286's 386's and one 1983 8088.

Ever tried using a program called MATLAB? I still stand on my chair at 4am and curse at my computer after looking for one simple little error. (ex: ./ instead of / ridiculous? absolutely)

I've actually used MATLAB quite a bit for work when I have needed to perform unconventional analysis routines, especially with large data sets. I have to say, MATLAB's de-bugging process is about 1000 times better than what we had for FORTRAN, which would not give you any clue, it just wouldn't run. Leaving you to look at all the possibilities.

I remember when debugging meant that you had to go in and find the bugs that crawled into the vaccuum tubes. And milk was a nickel and the dodgers were in brooklyn!

I love MATLAB for large data analysis, there simply isn't much better (that I know of at least). You're right that it'll give you an idea of where the error is, but not what it is. And if you forget that little ( . ) in front of something, you're screwed. This is the reason I hate programming...
