Let me know where you got this f/1 lens. I need to get me one of them!

Dennis or anyone,
If I shoot a train going 100+ mph on a sunny day, my aperture would be f5.6-8, should I keep my ISO on 200 or move it to 1000? I believe my shutter speed should be anywhere between 1/1000-1/5000 of a second. I may go to a station on the NEC later to photograph. Thank you

I would avoid any ISO above 400 on the D70. It is very noisy.

Good point there, Road foreman. I really have no reason to go above 200 on a sunny day. Yes, 400 is very noisy for sunny day.

On the NEC with a bright sun behind you, try the above exposure. Your camera should just about agree with that. With a bright silver train, the camera might want to stop down to an 11 or 16 or more resulting in underexposure. Come to think of it, that MAY be the reason for the underexposure of your posted shots.

Study the manual, read other books, and test, test, test. You have to invest the time. We can only guide you here; a full class in photography is beyond what a chat room can do. You'll get the hang of it.

Amen! It's almost to the point of just go out and see what works on your camera.

Asking the nuances about settings (which depend on the light and conditions when you're actually out there) is kinda like asking about what waist size you should get for a new pair of blue jeans. Just go try the damn jeans on and see what fits...the same thing for your camera settings!

Remember, digital shots are free. Take test shots at various settings, compare the histograms, and see what is working...

What's a histogram? Enquiring minds wanna know!

As usual, folks are talking technobabble to a newbie who is learning the ropes. Give the guy a chance .............. and stop being so "aloof". People learn better and faster when things are explained in a style they understand, not what you know after 500 years of experience.

Think about it.

Dave.

Sorry, Dave, but you're kind of jumping in here without knowing the history and lecturing without enough background to conduct that lecture. The particular newbie has had plenty of help here and has consistently asked the same questions over and over and over again, both here and via e-mail. Questions on the basics. And he gets detailed answers from a variety of folks but nothing seems to stick.

And, BTW, it's not hard to go to Google and type in histogram.

I appreciate your efforts to teach us (me) a lesson, but you need to know the background of a situation before donning the white wig and judging.

Think about it.

F/1.0 is so pedestrian. It's all about F/0.95.

I don't need to Google Histogram, I wrote an essay about it, and the Zone System: http://www.davesphotopages.com/11.html

If you want a copy of my white paper (17 pages) entitled "Large Format Photography And Fine Art Printing - 1990" I'll be glad to send a copy along. It's pdf format.

I usually side with the "underdog" and never assume a "whollier than thou" attitude, even when the student isn't exactly swift at getting it. We all had to learn at one time.

Dave.

Dave, I do some teaching myself professionally and I have to agree with Ween, John is just not picking this up. Many (including myself) have given examples, suggested books, websites to visit for indepth help and truthfully, everyone has been very patient to a point. He will need much more help and time than we can offer through this forum setting. However, if you think you can change the world here scooter, have at it! If you have tons of free time and lots of patience, maybe you could help him learn but, most of us don't have that luxury.

I think Canon actually made a lens like that. Hmm....

Canon and Leica both.
I heard a rumour of a Zeiss F/0.7 lens, but I haven't confirmed it yet..

Some people learn using visuals, some hands on but, the problem is how difficult it is to figure out which type of person that John is.

But yet you assumed a "whollier than thou" attitude with me in your attempt to 'scold' me, no? And also, isn't it kind of "whollier than thou" to brag on the paper you wrote on histograms and presume that I would want a copy of it?

You are correct that we all had to learn at one time, and as the n00b on the forums, perhaps you should learn a little about the forums here and the people who contribute before chiming in with "whollier than thou"-type posts regardless of how much previous photo or teaching experience you have...

Not at all, I have some knowledge which I could pass on to others as my contribution to those who wish to learn. I put my essay online, which, as everyone knows, is free and up for grabs, you might have noticed, there was no charge for this information. The same goes for my experience with 4x5 large format photography, I'm passing that on free of charge. I could easily charge several hundred dollars for this info on 4x5 photography.

............. and yes, I have teaching experience also.

Dave.
