Hello, my name is Gary. I'm having a hard time trying to figure out how to shoot long exposure shots during the day. I have google it and watched 4-5 different video on how to do it. But, all I get are under exposure. I shoot with a canon 6d, I'm in the bulb mode, f22, iso 100 and I'm using a 10 stop sd filter. Tell me if I'm missing anything. Now, I have been shooting boats on the river, with no shade around me at all, should that make a difference. Can long exposure shot be taken in bright day light with only a 10 stop sd filter, I don't know? Is there anyone out there that can help me.

Thank you

Have you tried covering up your viewfinder?

Gary, in my earlier response (see below) I forgot to mention that this method does not require taking the filters on and off the camera, this can all be done while the filters are on. You can compose and focus prior to installing the filter or do what I do, set the ISO to its highest setting, compose and focus in live view, then reset the ISO back to 100 before shooting. The cell phone light meter result is so close to the camera (in my case at least) that they are virtually the same.

Previous post: Hello Gary, If you have a cell phone I can offer a system that will quickly get you a proper - or very close - exposure the first time. I routinely use a 10-stop plus circular polarizer and figure the combination as 12-stops. First, download "myLightmeter" or similar app and "LE Calculator". Meter the scene with myLightmeter using your desired ISO and f stop, then transfer the recommended shutter speed to LE Calculator. It will give you the shutter speed/exposure time to use given the strength of ND filter you use. It will either nail the exposure or get you very close.

Gary my 10 stop ND filter came with a conversion chart. You take your regular exposure, and look for the corresponding shutter speed on the chart. Could easily be a couple minutes of exposure.


Here's one of many such charts. http://www.kellicleveland.com/photography/using-a-10-stop-nd-filter-to-take-long-exposure-images/

I'd say you need to be in bulb mode, also.

A 10 stop filter is easy to use. I use 1/30 sec.(without the filter on) and then what ever f stop or iso you want to use to give you the correct exposure at 1/30 sec. Then switch to manual and you f stop and iso stays the same but your shutter speed is 10 stops slower or 30 sec.
Make sure you lock up the mirror and close the shutter on your eyepiece so stray light won't get in.
Or get a ND filter app for your smart phone.

Sounds to me like you are not setting the shutter wheel to BULB. This opens the shutter on the first actuation and shuts it on the second.

The OP said he is in Bulb, which he probably would have to be in since he is overexposing.

If you use the built in meter, without the ND filter, under automatic conditions than add 10 stops you should be in the ballpark. Then, in manual with
the filter on, make the adjustments in exposure for a total of 10 stops which could be any combination of shutter speed, ISO or f stop. Good luck and share your results.
