Hello,

Will a 52mm Hoya IR filter work well enough on my Nikon D3000? I've read about a bit, and some say that some SLR's won't take good IR pictures even if a filter is in use.

Regards,
 
Recent Nikon dslrs (D70s on) aren't good for IR photography, you'll need a tripod and 30 second or so seconds for each exposure. At least the filter isn't all that expensive if you want to give it a go.

My avatar was done, handheld, using a converted D70s
 
Using a tripod and long exposures wouldn't bother me, i'm just wondering if the results would be decent enough?

What is a converted camera?

The internal filter over the sensor is replaced with an infrared one, it means that you can use it like a normal camera, without needing to resort to using a tripod.
 
Generally DSLRs are not very good at infrared, but some are better than others.

Digital sensors are sensitive to a wide spectrum beyond both IR and UV, and have filters over them to restrict them to visible light. However, if they they have a fairly soft IR filter that doesn't cut in hard right at the red end of the visible spectrum, with the right accessory filter it's possible to get a bit of IR going, mixed in with a bit of deep red visible light.

It can still look quite effective but not as good as a converted camera that has had the factory IR filter removed, and an IR passing filter put in its place. You can see through them and frame as normal too, as the filter is over the sensor and not the lens. These are the camera conversion folks - Advanced Camera Services http://www.advancedcameraservices.co.uk/
 
Get an ordinary tv remote or similar and point it at the lens while pressing one of the remote's buttons. If you can see in your liveview screen [assuming your camera has liveview?] a white light flickering on the remote, then your camera has reasonable IR sensitivity.
 
i have had reasonable results with a d300 some tweaking to be done in PS haven't had the time to try it with my d300s yet, give it a go.
