The Easy Way to Calculate Long Exposure times with your filters on your camera!
The most likely time to damage or break your neutral density filters is taking them on and off your camera. Rather than take your filters off to calculate your exposure time, leave them on and use this simple super fast technique!
All you need to remember is seconds at ISO 6400 = Minutes at ISO 100
In this video, I have used both the 10 stop and the 6 stop Nisi Neutral Density filters to maximise the exposure time.

I've been out and tried this and I have to say, this is possibly the most useful photography tip I've been given.
Many thanks again for sharing.
ITs a ripper isn't it :)
i know Im asking the wrong place but does anybody know a method to log back into an instagram account?
I stupidly forgot the password. I would appreciate any assistance you can give me.
@Major Keanu Instablaster ;)
@Reece Kairo thanks for your reply. I got to the site on google and im waiting for the hacking stuff now.
Looks like it's gonna take a while so I will reply here later with my results.
@Reece Kairo It did the trick and I finally got access to my account again. I am so happy!
Thank you so much, you saved my account!
Have to say, in forty plus years of photography, I think this is the best and most simple tip I have ever come across, many thanks, you have a new subscriber.
This is an excellent method for quickly assessing long exposure times. If you want to shoot at ISO 64 then test at ISO 4000 (approx 64x60).
Vincent O'Sullivan spot on! Thank you
This is the best I've seen re calculating exposure with ND filters. Thank You!
Adam's rule
This little video is carried with me everywhere - known as Adam's rule - I pass it on to all that I photograph with & teach !!!
Brill' !!!!!
I am a novice with filters, and after some frustration I contemplated tossing them to be honest. But that would have to be the best explanation I've heard in calculating exposure times. Can't wait to try it so maybe my filters will get some use after all! Thanks :)
Nicely done! Excellent video and beautiful setting - perfect demo. Thank-you for creating this. It helps a lot!
You're a bloody genius mate... big time!
hahaha Nah, I got this many years ago from a friend. Just passing it on :)
Many thanks for sharing adam.......awesome tip
My pleasure :) Thanks for watching and leaving a kind comment
I've been doing long exposure photography for quite a while, this a brilliant technique.
Thank you :)
Fan-bloody-tastic! I haven't heard of this tip before. Can't wait to try it with my shiny new NiSi kit. Thanks so much Adam.
This is amazingly invaluable. Can't wait to test it out. Thanks so much!!!
Brilliant way to manage settings in working with filters.
I saw this a while ago and forgot. Now i wanted it saved. It is a very good tip. I am a beginner and having ND on while calculating helps . It is fiddely wit entry level camera nad budget nd filters. The tend to move focus when screwed on. Thank you.
PS: My dslr goes from 200 iso, so in that case the time would be 1/2 minute instead of 1 minute ( pr second test exposure) . ;)
I was thinking the same thing that Tim Brown stated. That is a wondeful tip. Thank You much!!
David Banks pleasure
Great and simple way to calculate long exposure.........thanks for the tip!
My pleasure :)
Thank you sir... I am very close to making the plunge on the 100 mm NiSi V5 Pro Filter System as I don't believe they offer a quick ref. exp. chart. They do however build very high quality 100% Nano coated optical glass filters at an affordable price in comparison to the very pricey resin ( acrylic/plastic ) filters offered by the competition. So I forgive NiSi for this... lol...
The " Seconds @ ISO 6400 = Minutes @ ISO 100 " tip is of tremendous help for me, thank you very much!
Bill Farr... Vermont, USA... :-)
Hi Bill, the NiSi system is excellent and does come with a handy mobile app. However I find this system is faster and easier.
best of the best option to shoot
with ND filter on - great information - thanks
Pleasure! :) thanks for stopping by
I am gonna try it.
Great! Let me know how it goes
That's quite a neat trick for calculating long exposures :-)
Pretty cool hey 😃
Makes sense. Must try it out. Thanks, mate.
Thanks for sharing this method.
Superb tip. Can't wait to give this a go. Thanks for sharing.
Works great, you will love it!
Thanks for sharing the info, i'll have to go out and try this. This will make it so much easier.
Finally and easy peasy way to calculate .. I owe you a tall one
Really good info sir. Always like your tutorials.
Thank you :)
Great tip, hate taking off the filters to readjust although if you want to do a different comp you are going to have to take them off anyway to set focus. Nonetheless, still a fantastic tip and looking forward to trying it out
Mackymcd awesome! Let me know how you go
Can you see or, does the camera see to make focus if you crank the iso up higher? I do this with macro work but have not done long exposure filter photos before.
Great tip!!! I'm using this the next time I shoot waterfalls or waves on rocks
Cool, let me know how it goes.....
What a great tip. Thanks so much
Great video ! Great tip ! I don't like shutterspeeds that long though. During the 6 minute exposure the brightness (amount of light outside) can change a lot and the pic is over/underexposed
You will learn with experience to monitor that and adjust accordingly
helpful also when using manual focus..thanks
Good quick method for long ND images. Thanks mate!
Great video! Since my camera (Lumix G85) only has iso 200. I will do this using iso 12800. Let’s hope it works for my case, thanks!!
This is what I'm here to ask about. How did it work out?
Great video and well explained, thank you.
Thanks Max, let me know how you get on when you try it
Great tip. I'll try it.
wow thank you from England UK

Would this technique work at night with no filters?
great tip Adam, thanks.
Pleasure Bruce!
Very... Very cool !! I'm gonna try it.
You brightened the scene in post but was that beautiful rust there before ?
Nice job
Thank you! Cheers!
Thank you, i am going to try this
Great tip Adam
I will try it out next time .
Very Nice. Earned a new subscriber.
davidyanceyjr great to hear!
Thanks for the info.I'll be trying this out
Pleasure 😊
I’m going try this technique I’ll let you know when I’m done
Extremely helpful, thanks a lot
Pleasure!
Thanks for what appears to be a great tip for Long Exposures. I wondered what you were doing with your left hand during the time you were altering the shutter speed with your right hand,was there an action that you did not mention,or were you just keeping your camera steady? Ron
Just keeping the camera steady :)
Nice one..
Thanks mr bobb!
Blimey! This is genius!
hahaha maybe not, but a nice cheat all the same :)
Cool tip. Do you reckon your initial 6400 exposure was thrown off by light coming in the viewfinder? I do find that if I meter on my canon without my eye up to the viewfinder, or with it uncovered, I tend to get an underexposed image.
Cheers
andrewford80 Nikon have a rear shutter for the eye piece. If I leave it open it will stuff things up
ooooohhh I can't wait to try this. thanks m8 great tip.
Let me know how you go :)
If your cameras base ISO is 200 would you just halve it again based on the correct exposure at 6400? So on your example 3 minutes instead of 6?
geoff stapledon exactly 🙏
@@AdamWilliamsCreative Sweet. Thanks mate
Thanks for asking. This is exactly what I was scrolling for!
You're a champ. Thank you.
Pleasure
Thanks so much for a great video I was getting so frustrated with my ND filters, can’t wait to try your formula. Do you have similar formula for 6 or 10 stop filters?
Hi Chandan, the formula works the same no matter what filters you use
So when you check exposure with filters on, is the focus on auto? Or do you use manual?
Go to manual, the auto focus gets confused with the filter on. JE
Yeah manual, Auto will hunt and mess thing up :)
for fuji iso200 we use 12800 or 3200 ..?? or the sane?? iam confused eheh
Arménio Barão 128000
I'll have to try that trick...
I normally carry my quickie reference table Filter Factors; or I do the math using the Filter Factor, my calculator along with what my light meter tells me about what my base exposure is...
Nice video nonetheless.
great tip, thanks!
danteuss88 pleasure 😊
Great video nice
Thank you Divi!
Hi! I'm using a 10 stop ND shooting at f/16 100 ISO and anything over 40 seconds is blown out, way over exposed. How exactly are you achieving this shot during daylight with a 6 min shutter?
I have the 10 & 6 stop in together
@@AdamWilliamsCreative Thanks for the quick reply! I guess it would have helped if I had actually read the video title haha, my fault.
would appreciate your support ......How to decide which size filters to get ....??? 100mm or 75mm??? I have a Sony 7r mark 3 ...????????????
Really depends on how wide your lens is. Contact your local NiSi supplier and they will sort you out. If you haven't already be sure to subscribe and then join us for the LIVE Shows!
Awesome . Thank you
Pleasure :)
Nice work Adam. I assume you need to lock down your focus prior to installing your ND filters?
Spot on David
I had the same question...so if this be the case, then you have to put it on after you focus. So you still can't get away with removing it and putting the ND filters back on and off..
bassplayer60 well unless you want to leave them on in your bag, you will need to put them on and off at some stage. Set up comp, set focus, put on filters, calc exposure. No need to take them on and off during the shooting process 😊
Hi Adam - Great tutorial. I am curious about how you know your camera's f Stop is incorrect. Thanks.
Hi Laura, my lens doesn't communicate with the camera so it needs to be set manually, for whatever reason the camera doesn't read the stops properly in manual
nicely explained tip. But how about setting up composition? It seems like every time you set up a composition you'd need to remove the ND filter(s) anyway.
Jason Thomas you would obviously set up the composition first before adding the filters
Really great tip. Similar to the Sunny 16 rule I imagine. Can we call this the Adam 6400 rule?
I would love to take claim, but I heard this many years ago from another photographer (which I can't remember) Just the 6400 rule sounds good
I go on the premise that there's no such thing as a dumb question: Actually less of a question and more a confirmation that I'm understanding this video which I've watched about 6 times. I decide on composition, set up on tripod, using AV w autofocus on compose scene. Put on filter, change ISO to 6400 & see what exposure time reads in seconds which I will convert to minutes. Switch to Bulb and use cable release....my question is how does the camera read anything with filters ON? I was taught to use an APP....but really would like to use this as it is much simpler......Big thanks in advance for your response
rosalie bischof all you are doing is taking a highly sensitive test shot
If you use auto focus, switch back to manual focus to lock it after you have achieved your focus and then put the filters on. To adjust your exposure it is recommended to put the histogram on, that will tell you if you are under or over exposed. Histogram is your best friend here! I don't know what AV is but he is using M for Manual all the way. After the "seconds" test-shot, do not forget to switch to bulb-mode for longer exposure.
Tried this on fujifilm x100t with an nd8 plys nd4. At 6400 iso it gave 3 sec exp at f11. So i figured at iso 200 1.5 mins. Image was way over exposed. What did i do wrong?
My best guess is you tried it in changing light conditions like sunrise. Or the sun came out from behind clouds
@@AdamWilliamsCreative hi thanks for getting back to me. I was trying indoors just to check if I could make it work.
THANKYOU...
Subbed ya mate. Quick question for you. How would that change if it was a 9 stop filter and you're using f16?
The Happy Hour Hound that’s the beauty it doesn’t change. Regardless of settings and filters, seconds = mins at iso 6400 - Iso 100
I have difficulties to read the ride exposure times on the nikon it has no / sign so I can't use an app and also your tut I realy don't understand
Let me know if it works perfectly for you too!
How do you factor for a camera with ISO Ranging from 200-3200 such as the NIKON D300?
That’s a little tougher, basically every second at 3200 will equal 15secs at 200. Or in other words 1min for every 4secs
Interesting, thanks
And Shooting film?
Christopher R. Perez grab a light meter 😊
@@AdamWilliamsCreative :)
Does it matter how many stop ND filter we use?
Nope, the same theory will work regardless of filters
what about focusing? Do you use infinity?
Sometimes, depends on what the scene requires and the closest details to the camera
The question is how do you focus without taking the ND filters off? Isn't that what you are saying?
I understand Sir, but you had me about the not to have to remove the ND filters on and off. But I
guess you have to...to focus...lock down and then put the ND filters back on again. So apparently
you can't get away from the on and off ND filters...but what a great way to figure out the exposure time. Thank you!
bassplayer60 nah, just focus before you put them on and then lock it off
Thank you for your technique though...aside the on and off...this method works fantastic...Thank you so much!
Surely this applies to only using a 10 stop filter...?
Nick Coburn Phillips, nope, works with all combos
Awesome
the perfect calculation is your instict
Jan Robin you mean like an educated guess? Nah, I would not recommend that
Oh sure, tell me this now. Not yesterday when I was perched precariously on a slippery ledge trying to nail a 10-stop shot without falling into the rushing river.
HeliRy hahaha sounds like my kind of fun!
Well then, move over because you should have seen me yesterday at Raven State Park, NC ...Muddy, slippery leaves on the edge, A Big Rock at the bottom and a raging river trying to nail a 10ND...Yeah! What's your deal?! LOL!
Is it me or does anyone else think the rock looks like a lion?
Know you mention it, yes it does :)
Ozzie Ozzie Ozzie oi oi oi.
Are we not entertained? 🇦🇺
so lost ...
Seconds = minutes
That wasn’t easy. The easy way is to use an external light meter.
come on Roger step into the digital world we don't carry light meters around any more :)
Still easier if you don’t want take filters on and off. 😀
Rodger, why use an external meter when as demonstrated the one in camera works perfectly
Adam Williams Creative because I can check changing light conditions without removing the nd. I thought your technique was interesting and of value but when it came down to it it really amounted to trial and error until you got the exposure right. I’m just starting out with trying to get fine art photography with long exposures. Went out this evening with disappointing results so I have still got a lot to learn. I am definitely no expert so I am not trying to tell you how to suck eggs. I just made my original comment with tongue in cheek. Cheers.
Awesome formula. Very usefull. Thanks a lot!
