Post Lee Big stopper
First play with a Lee big stopper on a Canon 5D MkII and Canon 24mm f1.4L mkII lens.

I like the moody feel of the image created by the misty appearance of the water. I love the streaking clouds! I'm looking forward to experimenting with one of these filters.

If you were to shoot a colour-chart/grey scale using a 'normal' exposure and a long exposure, is there much of a colour shift between the original two before colour grading/matching?
The older high ND Tiffen filters I use exhibit a significant magenta/orange shift.

I'm not seeing any obvious colour shift with this filter. The image was shot at 6200K which is the manual white balance I always use for raw work and I didn't see any need to correct it during the conversion. The image is slightly cold i.e blue but it suited the image.

I don't have access to a colour calibration chart but I can shoot a couple of images with and without the filter today and post them up for you to have a look at.

On a side note Live view on the 5D easily handles the 10 stop filter and you can compose and focus without having to remove the filter :)

regards
Kev

I ran a basic test on the Lee big stopper this morning down in Cemaes Harbour and what I said in the previous post is rubbish!

I took 3 photographs with the Canon 5D MkII and Canon 24mm f1.4L MkII lens. Why three? well after shooting with and without the filter using the 10 stop exposure correction given by Lee I noticed the filtered image was underexposed by about a stop.

There is also a blue cast produced by the Lee big stopper. Rather than try to describe the effect of the Lee big stopper I have uploaded a zip file containing the 3 original raw images (CR2 format) straight from the camera so you can assess the images yourself, it is 70Mb so be patient :)

The Lee big stopper filter images are here http://www.photosbykev.com/misc/CB_220810.zip

PS Now I know why people go on about covering the viewfinder, during the ealy morning test the sun was directly behind me and fairly low and one image came out like this ! First time I've ever seen this happen and I used a rear lens cap to cover the viewfinder for later images.

Thanks for the test. Illuminating.
I sometimes use the 5D2's lens-port/body cap to fit over the OVF(Optical Viewfinder) to prevent backlight interference - you can push it on over the OVF and it usually stays in place even when tilting the camera.

Another suggestion: If you have the Kendrick 'camera cosy' option for dew control, try adding the hood to block out stray light. It's very easy to adjust and sits pretty tight over the camera. I've also used it to protect against spray in beachy environments.

Damn you Colin, everytime I come on this forum I see something else I need to buy ;) That cosy camera and dew control heater seems ideal for timelapsing because condensation is starting to become a pain this time of year.

Hi,

thanks for the comparison Kevin.
I got the 10 stop resin filter from Hitech, from looking at your RAW files I would say the colour cast of both filters is very similar.
Looking at the price and the good availability the Hitech is a good alternative IMHO.
If there is interest I could take some photos with and without the Hitech filter tomorrow and upload the RAWs.


Best Regards
David

Eric -

BH Photo Video and several other vendors have them on back order in the US. I have not been able to find any company with them in stock so I have ordered one form each of several on line camera vendors. I have been waiting notification for about 5 weeks now. Good luck finding one.

I've just ordered a pair of the tea cozys and firelite dew control systems from www.altairastro.com in the UK, thanks for the info Colin, they look ideal for keeping the mositure off the cameras and lens.
