Guys, i have a 8mm samyang fisheye lens and use it with a D7000. i would like to do long exposure shots with it but am getting all my pics blown out of the sky (20sec exposures etc). id like to use a gradguated ND filter on this lense to prevent this happening but not sure if possible due to the curve of the glass, is there a way this can be done? if so would someone please help me out even if theres any other way to avoid the blow out without using a ND filter (like a trick of the trade perhaps )then thats even better rather not use a filter. i have tried the cloth trick in font of the lens, but due to the wide angle of the lens im finding it hard to not get my hands etc in the picture cheers
IMPORTANT: there are two types of gel filters! DO NOT get the type that are used for theatrical lighting. They are NOT of optical quality and will render your images useless. MAKE SURE you get the optical quality version that is designed for use as a lens filter.
I hate when people ask me what I see myself doing in 5 years...... I don't have 2020 vision!
All of the advice given is 100% accurate, but do note that the request is for a graduated ND, which is going to be very, very hard to get right in any situation involving rear filters.
With a fisheye, I don't bother with filters. (That's especially true since my main fisheye is an 8mm FX circular fisheye that's even tougher, since it is 180 degrees in all directions!) If I have the sky blowing out, it's time to shoot an HDR. If I have to do this, it's usually a five-shot bracket at 1 stop intervals, and I usually need all five of them. This does not *always* work, but I think the problem is Photoshop and not the captures. Still, it works about 95% of the time for me.
