Cant see any noticeable colour cast on my monitor which is calibrated so should look ok.They sure are. Not really Infra Red weather at the moment but went out yesterday determined to get some shooting in:

Can anyone see a cast on the monos? They're colour output from the Zomei filters. I can't see any cast on my screen though the histogram tells me there should be some areas of colour, my phone shows a teensy tiny bit of purple perhaps. For some reason however, if I try and process as Black and white in lightroom the exposure is suddenly dropped, likewise if I slide the saturation all the way left or try and use a camera monochrome profile. Very strange.
Given that you'll be moving, albeit gently, I'd choose one that has quite a low filter factor so that your choice of shutter speed won't be restricted too much.I'm taking my EOS M full spectrum, what would be a good filter choice please?
Are you saying that the exposure value of the scene is the same whether you use your 680 or 850nm filters?But if it's a full spectrum with a filter on the front of the lens, it should behave as a normal camera regarding shutter speed - mine does. I can normally shoot at 1/1000 easily in good light - obviously as the light drops so does shutter speed.
No but generally shutter speed is not an issue on a full spectrum or converted camera as it is on a non converted camera. As long as there is sufficient natural light around then shutter speed is not really a problem - at least I've never found it to be on any of the conversions I've done. My current Panny G1 has no issues with shutter speed as long as the light is good - obviously if the light is bad with little or no IR, you are in trouble - but on a full spectrum conversion, you can just use it with no filter at all and just go for the retro washed out look.Are you saying that the exposure value of the scene is the same whether you use your 680 or 850nm filters?
thats really nice james ^^
