10 Stopper exposure metering

Hi all,

Sorry if this question sounds a bit daft, but have just started using 10 stop Hitech filter. My question is -

How (or rather what) do people generally meter off when using a 10 stopper? A specific example would be shooting a sunrise/sunset over a lake..would I go for the foreground or a much brighter sky, alternatively do toggers use a ND grad on top of a 10 stopper and meter off the foreground?

Thanks.
 
Hi I cannot link because I am on my phone, there is a thread in the lighting section on the first page which will answer your question.
 
I've just bought a ND 0.9 hitech filter and might get the 10 stop also, would be really interested in the pics you get Anand!
I found a good guide here: http://www.redbubble.com/people/pet...the-ultimate-guide-to-neutral-density-filters

The how to use part is 1/4 way down.

Thanks for the link James...yes, just read it now..says there is no reason why a CP or a ND grad can't be used with a 10 stoppers...and yes, it's more or less trial and error apparently...TBH I was infact doing this but thougt there would have been a better way :thinking:

will post couple 10 stopper image taken some time ago..wasnt really impressed with my skills in that avenue..see what you think about the quality

I use whatever filters I would have used for a shot without the Big Stopper, then put the big stopper in.

My workflow for a 10 stop shot is this;

1) Compose, get the shot looking right in the viewfinder, including what I want in the shot and, more often more importantly, excluding what I don't want in shot
2) Focus, then switch to manual focus
3) Meter, with both the camera's internal meter and an external spot meter
4) Expose for a standard shot
5) Apply filters as necessary to get the exposure right
6) Take a test shot at a short shutter speed
7) Examine the histogram on the short shot for blown highlights or blocked shadows
8) Adapt exposure according to step 7
9) Work out 10 stop shutter speed
10) Close viewfinder to stop light leaking in
11) Check AF on manual and IS turned off
12) Slide 10 stop filter into position checking it covers the entire lens
13) Set the exposure up, either on bulb or with manual setting
14) Check mirror lockup is switched on
15) Lock mirror up, give it a second for any vibrations to die out
16) Set shutter with cable release, either one shot if it is on manual (eg less than 30 second exposure) or lock it off if on bulb.
17) Check top plate exposure timer and also chronograph for exposure time
18) Walk about, try and keep warm for up to 32 minutes!
19) Unlock shutter release when exposure time reached.
20) Review shot and reshoot as necessary (if I am doing a long exposure at dawn or dusk the exposure time is a bit hit and miss as the EV of the scene changes during the exposure).

This shot for example was shot with a Big Stopper and a 3 stop reverse ND grad for 4 minutes.

Some where on the forum there was a chart uploaded by one of the members,i think it was last year & it gave you the meter readings you need to use when using a 10 stopper.:shrug::)(y)
Maybe someone might remember that.
 
Is this what you mean ;) not the best layout but gives you an Idea (y) there will be better ones out there, this is what I use for my 10stop B/W

The Flamborough arch is superb and captured nicely.

I too would use a grad (usually a 3 stop) on top of a 10 stop filter. There is a chart somewhere giving exposure times.
 
Anand, here's a link to tutorial. May assist.

Mark, great shot of arch. Have kayaked through that arch. Must try to get there on land - guess that was a sunrise shot. Can you give your location from which shot was taken?

Hi Ken, I was up on the clifftop, to the South of the lighthouse, if you go into the shot on flickr and click the map at the top right you can zoom in, all my shots are geotagged. Glad you like it.

Very very useful...would say thats a brilliant step by step guide..thanks for that Mark..I definitely never use to expose for standard shots and check for blinkies, histo, etc..just use to attach my 10 stopper and fire on..this will definitely change my approach...thanks..(y)

BTW love your image...absolutely stunning..will be over the moon if I am able to get something like that in future ;)

Thanks for that as well...was looking for a chart online as recently changed from iPhone to Adroid...and it seems android market dont have a suitable long exposure calculator (unless I am wrong):shrug:

Thanks Ken...will have a look..

if you're up to going to that location, might join you unless you wanted to be on your own :)

There is also an app to calculate the exposure times, I think it is called 'long exposure'. Thanks Mandy

Thanks Mandy...yes, it is a really good app...unfortunately, adroid dont seem to have it.
 
Easy way to set the shutter speed is to count the clicks. Ten stops is 30 clicks on the dial (if it's set to 1/3rd stop increments, as most are by default) down from whatever your starting point is.

To get it dead right, you need to check the density of your filter first. They all tend to vary a bit from marked, by maybe 0.3 or 0.5 of a stop batch to batch. Just take some tests shots and then adjust the dial count - 29 clicks or 32 clicks whatever for all future pics.

Thanks for your reply Richard..I am afraid just bit lost here..i think i do understand the concept but not sure if i can get to 30 clicks? would my camera not go to 'bulb' mode after any more than a minute?

LOL Yes! It only works up to the camera's longest shutter speed, usually 30secs, before you go into Bulb.

In which case, if your normal exposure is longer than 1/30sec as a starting point, with a ten-stgopper you're going to need to time it manually on B.

Just on that, I don't know if this applies to all cameras, but on many models once you press the shutter on B, the frame counter switches to counting the number of seconds - saves you using a watch :)

Thanks Richard..thought was missing a point which I easily do..:). Probably the formula would be more useful on lower ND numbers?? Silly question again, how did you calculate 'ten stops is 30 clicks on the dial'?

Don't think I've got that timer on my Nikon :thinking:, need to check..thanks.

If your exposure adjustment is set in one third stop increments, which is the normal default, then 3 x 10 stops = 30 clicks.

Sounds a great idea for a meet or mini meet. Just trying to get back to normal after a month of visitors for Christmas and have a window of a couple of months before a knee replacement op which will put me out of commission for a while.

For those of you who use the iPhone, there is a brilliant app called

+ 10 stops which is available from the app store.

It's the best app, purely for the Big Stoppa and Hitech 10 stop filter, that I have found.

Andy
 
There's a free app for iPhone users called "Long time exposure" Pretty simple to use, you enter your exposure time without any filters and select the strength of filter you want to use :D
 
Just found this which might be useful

http://www.flickr.com/photos/weeman76/4440416905/

This is the app I've got on my iPhone - http://www.nsonic.de/blog/software/ndcalc-iphone/

Dont worry when you download it, it is in English!! Trust me haha
Thanks for that..have just stored it on my pc :)


Just downloading it now...hope its as good as iphone long exposure calculator

Wonderful Ken...any suggestions for dates..can put it up on 'meeting places' then, and see if there are more interests..2/3rd weekend in Feb seems okay for me at present but quite flexible if you wanted to leave it till later.
 
Can't do 3rd weekend, Anaud, but 2nd OK with me at the moment.

Could leave it a little later but by end of March I could be having op and then out of action for quite a while.

Need some clear skies.

Right...let's aim for either 2nd week in February, if the weather is bad we can always postpone it to first week of March. Would you want me to start a thread to gauge other interests?
