Ladies and Gents,
I have a small collection of 2 and 3 stop Lee, Hoya and Hi Tech ND filters - all graduated. When I tried some long exposures there was a strong magenta tint which, I have learned is most likely from the filters. Since I want to get into long exposures for interesting applications as well as the more common uses, I thought I would bite the bullet and get 3, 6 and 10 stop solid filters that are not at the low end and that will not have any color cast. I know that there are a number of manufacturers and I will have to price compare. One question is whether I should get screw on filters or use a filter holder with square or rectangular plates. I will need a filter thread of 77mm and have the step down (up?) filter rings. Before I spend a bunch is there any advice to help me spend wisely?
Thank you,

THe magenta tint with long exposures is a result of light leaking through the viewfinder onto the sensor. See example att from a 20 sec exposure. Some Nikons have a viewfinder shutter to block stray light. A small piece of gaffer (not duct) tape on the viewfinder, or that plastic viewfinder cap (the one that came with your camera that you've lost) will do the trick.
rgrenaderphoto,
That may be true but a lot of folks on this forum feel it is also due to some filters that are responsible for the color or tint shift.
Some filters are specific about not having this problem. My collection seems to have the problem.

I use Lee filters - they are considered one of the top brands though there are other good filter manufacturers. Nisi have been mentioned and they are also considered to be a good make. One of the questions you asked is whether to get screw in filters or a holder into which you can slide your filter(s). One of the main attractions for me with the holder option is that you can have as many as 3 filters in at a time - I'm not sure that screw in filters allow this. Lee filters are supposed to display a blue colour cast but I'm not sure that I've been aware of it. I primarily just use the solid NDs now and of course a poloriser - I have a huge array of grads but seldom use them as you can get the same effect in post. One of the respondents mentioned the use of tape on the viewfinder when taking long exposures - I did do this with every shot but seldom do now - I've had one or two issues when I haven't, particularly if the sun is directly behind the viewfinder so I still keep a roll of electricians insulating tape in my bag.

I have some Lee ND filters and have not noticed a color cast. Could be stray light not entering through the filter as previously noted.
The problem with screw-on filters is that you need to focus first and then put on the filter, then for every new shot go through the "screw filter off - focus - put filter back on" routine. That's the system I have, and it works, but it can be a bit of a pain. It would be simpler just to be able to drop the filter into a holder and take it out again as needed.

There’s this: magnetic filter ring:

Thanks for that: I had never heard of those magnetic filter rings.

Filter color casts from inexpensive coatings usually manifest in the sky as a green tint.

The Lee 10 stop ND filter will give a blue color cast on long exposures. It can be corrected in post by setting the WB to 10000, or set the camera WB to 10000.
Light thru the viewfinder will not cause a color cast, usually streaks at the bottom of the image.
I bought a set of Gobi 3/6/10 stop screw on filters. The company is Australian and does not have a lot of reviews but the reviews I did read pusuaded me to try them. They work great for me.

As long as you do not attempt to stack screw on ND filters. You will get vignetting.
