InfraRed

I had a search around other forums and couldn't find anything in one of the general comments about InfraRed filters.

I have a D5300, and I don't want to get it converted to shoot InfraRed only, as I don't have the money and it's not something I'm looking to do long term. But it does interest me, and I would like to give it a try.

At the moment, I'm looking at some 720nm filters, which just screw on to the end of my lens. I've seen a lot of different opinions online after Google searches, and some great images that claim to be shot using a 720nm filter. I'd just like to get some feedback from you guys, if you've ever used a similar filter, and how you found the PP work required to get the expected results.

FYI - I know we're in the middle of summer here, but I'm looking to get some nice scenery shots when spring hits and we start getting the greenery back and getting that white, fantasy type look on the photos.

I'm OK with the PP work, I'm just not sure on the filter itself. Thanks.

When I was looking for a 720nm filter for my D7000 the general census seemed to be that cheap filters gave bad colour casts. Not wanting to spend £100 plus on an expensive filter I bought a cheap (£10) Neewer ir720 of EBay. Wasn't expecting much but it is a great filter with no colour cast. So saved a pile of cash and got a good filter. I then bought the Neewer ir850 as well as at that price it is well worth it.

I knew I posted this topic already!

So are the results better from the 850 than the 720? Or is the difference insignificant? I've seen some bundles that offer IR ranges from 720 up to 900+ in one bundle, and I think it was only £23 for the 52mm screw on. But as it's my first time, I'm looking to keep the costs down until I'm sure I can grasp it properly and capture some decent shots.

"Better" results from an 850nm? No. Different results for sure.

Take a look at this from the folks at KolariVision on choosing a filter. These are all done with converted cameras, but they do sell filters as well (yes, the "expensive kind") and you can assume that the filter on the front will be similar - but remember, your sensor stack has some IR filtration built in, so you may lose some of the light/color.

Also realize that the more light you filter out the longer an exposure you'll need, so putting an 850nm on the front of a lens may require prohibitively long exposures if you want everything crisp, because tree branches will move.

Thanks for the link, certainly explained a lot better than some other sites I've been on to, and with good examples too.

I'll be mostly doing channel swap type shots, rather than B&W, so I think I'll stick with the 720 for now. I am aware of the extra exposure time needed, so I'll be choosing my days wisely for when I go shooting in IR. Thanks again.
