Yeah, that's how I used to study for tests way back. Spend my hours making really detailed cheat sheets, then comoe test day leave them behind. Making the crutch halped my study on concentrate on the real important information. I could just never getthis to work for calc :mad:

It is actually quite interesting and so far the theory is sound. To cut a long tutorial short the basic idea is this: You look at a scene and visualise it as you want it to appear on the film. You ligh-meter the important subjects in your scene and then assign the middle subject to Zone 5, the middle subject is the subject closest to 18% gray. The zone system has a range from Zone 0 to Zone X, 11 zones in total. Each zone represents a f/stop higher than the one before and lower than the one after. It is important not to say Zone 5 is always f/5.6 or Zone 8 is f/8. The zones "slide" up and down the f/stop scale depending on the scene, you just calibrate it to the middle zone, Zone 5. The zone system then also maps to film densities, which is very important. Zone 5 is mid density with full texture, Zone X is full density with no texture, Zone 0 is no density with no texture etc. etc. Now comes the cool bit. You can then say "I don't want my middle subject showing as 18% gray, I want it lighter, but still retain good texture." Lets say at Zone 5 in this particular scene the f/stop is 4. You would then say bump up the middle subject to Zone 6, that is one f/stop higher, which is f/5.6. That is what you set your camera to. Naturally then if there were other subjects you wanted in the shot then they also scale up or down the zones in relation to your middle subject. The whole point really is to give you control in saying "Can I get in all the detail of this scene, the shadows, the middle and the highlights?" or you can say "I want as much detail in the shadows as is possible, sacrificing the highlight details." The zone system then gives you the tool to do that, with the end result being an f/stop that you punch into your camera and use. And because light-meters return a shutter and aperture number you need to know the f/stop scale so that you can map it effectively to the zone system, and then back again. All very cool :-D

Call me in two weeks. Chris Maunder wrote: The other option is just to take a glance at the lens on your camera This is actually quite annoying. So many tutorials and elder photographers say "Look on your lens for the f/stop, distance and hyperfocal numbers." I look and the only numbers on my lens are 28 to 90 and a daft picture of a flower with an infinity sign after it. I thought at first it was just my bundled kit lens that was lacking. Then I checked that Tamron out and it too only has the bare minimum of numbers on it. Seems as newer lenses are simply not printing these numbers on them anymore, rather relying on the camera body to figure it out or other tools. Tis a pity because looking at some older lenses those numbers are quite helpful.

Bah!' :-D Family and friends are begining to wonder if I am going to have my camera slung over my shoulder when I walk down the aisle one day. I take it absolutely everywhere, had to argue and then bribe the cinema lady to let me take it in, even had to show a bouncer that it was just a camera and not a concealed-weapon when I went out the other night. Hell, I was playing pool two weeks ago and had it clipped to my belt. I don't want to be like some photographers who whine "There was this perfect shot and I did not have my camera with me!"

Wow! :omg: I'm impressed. In my days, you adjusted the roll type and exposure time, and the light meter would tell you "too bright" or "too dark" (an f/stop, if it was an external device). You'd simply point it at the object to have average light (or +/- one stop manually) . Seems similar, only less concious/rationale. (I didn#t read the long tutorial, though)

(I didn#t read the long tutorial, though) Yes that is all used in the Zone System to setup the scene. The problem though with not thinking of zones and just intentionally over or under exposing is that you are only controlling the exposure of one of the subjects in your photo. With the ZS you can with some practice and thought control the exposure of 2 or 3 differently lighted subjects.

I was referring to the formula - start with 1.0, multiply by 1.4, round. Repeat as necessary. You can even skip the rounding - sure, (1.4)^5 = 5.4, but that should be enough to jog your memory to remember 5.6 as the actual setting. Don't be frightened... it's called math, and it won't bite...:-D Nobody wants to read a diary by someone who has not seen the shadow of Bubba on the prison shower wall in front of them!

You have a light meter, yes? All you need to know is to follow the light meter and then adjust from there. ie. shooting into the sun, the light meter will tell you to have a really small aperture which in turn will make your shot intolerably dark - solution drop the aperture by a stop or two. You dig? J

:wtf: Alrighty... you can probably ignore my previous reply. Clearly I don't have enough "steps" to my technique. Sounds interesting though... J

Jamie Hale wrote: Clearly I don't have enough "steps" to my technique LOL well if you like your technique and it works well then a: Stick with it and b: Share! I stumbled across that Zone System and it was recommended enough to warrant looking into. Also my explanation is obviously very brief and flawed as I am still learning, so check out the tutorial itself to judge. Jamie Hale wrote: You have a light meter, yes? No, I wish. Managed to afford the camera and lens, now saving up for a good light meter, some filters and another lens. The in-camera light meter is pretty good, just lacks a spot meter option though :( So where is your portfolio? What lens, camera, film do you use? What are your secrets? :-D

Paul Watson wrote: So where is your portfolio? What lens, camera, film do you use? What are your secrets? Err, well, you see... the trouble is... Well ok. When I'm not using my digital (and since the birth of my daughter it's what I seem to have used exclusively), I use one of these[^]. The lens is a fixed 50mm I think - I'd have to look. The camera has removable backs so you can load up a black and white AND a colour roll each in their own back, and swap between them as you please. Mind you they're quite old and I don't trust them to keep out the light, so I don't use that feature. I shoot black and white mostly, and before my parents moved out of their house, I did a lot of my own developing in their darkroom. As for secrets? I guess for me it's mostly in the subject matter. I have a lot of pictures of peoples' backs because they were looking at something in particular, or in a certain way. And I have a lot of nature shots because it's so easy to capture something beautiful. Sure lighting is very important, but I find poorly lit pictures of something intriguing typically better than well-lit pictures of not-a-whole-lot. Know what I mean? J
