ok, nik-super8, I guess you are a bit suspicious about messages like "kodachrome's gonna end" & stuff like this but it's kind a while I'm posting here. What is a forum if anyone's gonna get paranoid about every messages ? What about your post ? What's telling everybody here that your message is true ? Will everybody mail Kodak to get a personnal answer ? ...

Matt

ps: Chessy, I guess you'll have to buy a handheld meter. You won't regret it .

Hello Matt(hieu),

I`m quite surprised by your reaction to my message.
I did not want to question or to attack your credibility.
I think it is human and realistic to be a bit cautious about messages on the internet even in this forum. I think it helps others when facts are proven.
You should be happy if somebody supports your message.

You claim, you are posting here for a while but unfortunately only as Guest. Time and quantity of posts are no arguments for credibility and quality.

I`m not paranoid, I take a realistic view in my life. Everybody is free to do what he wants to do. By the way forums are living of the discussion of different points of view.

There is no "absolute truth" in the world.

Je pense, donc je suis.

Please be a bit more careful when posting replies.

500 ASA stock on s8cameras

Post by nagaarjuna »

HI!
Good question. (what cameras could take this kindof stock and how). The thing to remember is: What does the ASA-setting make the camera do? Nothing, really, but to things: First, it sets the exposure when operating on automatic, and secondly, it shows you how you´re doing via the lightmeter. (If I haven´t misunderstood completely).

Having a ZM II would for me mean dropping the option of going automatic on exposure (which I hardly ever do anyway). Instead, it´d be quite easy doing it manually: Just put the ASA dial on 400, and then close the aperture down one more stop in relation to the meter reading. Conversely, if you use a seperate meter (which I would recommend for proper results), you needn´t even think that much.

Of course, this could be done with practically any camera, but not having aynthing beyond 160 ASA means more adding up.

And hurrah for da nu STOCK!

Ok, I think I get it. Sounds pretty logical. But how can one tell or relate the proper amount of f-stops to the missing sensibilty? If I follow the white-and-red-dots-rule on the 4008's ASA knob (where 1 f-stop down takes you to half the selected ASA value and 1 f-stop up takes you to twice that value), when set up at 400 ASA, 200 ASA is 1 f-stop down and thus, I should theoretically get 800 ASA if the knob could go 1 stop higher... So if I follow this logic and I want to use 500 ASA stock when the camera's set at 400, I should rather lower the aperture about aprox. 1/4 f-stop because 1/2 f-stop up would've been 600 ASA if the knob could go that high. Am I wrong?

By the way, I never use my cameras in automatic mode, unless this is the first time and I wanna know how it reacts. :wink:

100 Asa isn't equal to one stop. I think it is better to put your light meter to 250 ASA and then close your aperture down one more stop. The difference between 250 and 500 ASA is one stop. 40-80 ASA is one stop difference; 80-160 Asa= 1stop. 125 ASa to 250 ASA is one stop. 250 ASA - 500 ASA= 1 stop. See the logic??

Hi Nik,
I think it helps others when facts are proven.
So tell me what your message prove ? Why anybody who red my former message & get suspicious would be reassured by yours ??!?
There is no "absolute truth" in the world.
True, nor mine, nor yours.
You claim, you are posting here for a while but unfortunately only as Guest
Yes, because I had problems with login in on Hostboard.

100 asa isn´t one stop. You´re absolutely right, Paul! Sorry for my obscuritanism!

as has already been suggested a handheld lightmeter is always going to be your best bet, but that doesn't mean the builtin lightmeter will be useless with this stock. I have a camera that only supports up to 250ASA and doesn't have manual exposure. When I can get my hands on some of this stock I plan on using it as is for 2 reasons:

1)negative stock has the least grain when slightly overexposed, the great amount of latitude it has should allow this stock to work fine with 1stop overexposure, this will result in highlights being blownout sooner(still shouldn't be as bad as video) and will give more latitude in the shadow areas. If you camera supports 400ASA then this stock should meter just fine as is, even 125ASA Ektachrome stock works fine in cameras that only support 160ASA stock, and it has a lot less latitude than negative stock.

2)The times I would be using this stock would be in low light situations, so the lens will most likely be wide open no matter what the meter was set to, of course if the amont of light varies a lot this might require a bit more work to keep a good exposure on the video transfer.

I haven't actually tested this yet so don't take my word for it, but I believe the results should be good.
