Hi recently I'm thinking to venture into IR photography.
But the trouble is I do not have a camera for it and therefore i was thinking to get a cheaper 2nd hand camera (canon 300d or 350d) for conversion.

Now I'm in the middle of wondering what wavelength do the few pictures below:

I know protechrepairs.co.uk offers a few types of wavelength...
But which one is best for those picture above?

Please help

Thanks!
 
Since they've all been PP'd pretty heavily it would be impossible to guess. The lower the wavelength the more visible light you get and hence more false colour, higher wavelengths are better for contrasty B&W. I use a 720nm filter, but I'm not sure whether bthat's at cut off or 50% transmission. I have ordered a 680nm one to trybut it hasn't arrived yet.

Bear in mind also lot of Canon and nikon fit lenses are no good for IR.

Here's one of mine:

 
That reminds - my IR filter completely knocks out eyes to black, so it's probably a 650nm filter on those.
 
thanks!
If I want to get into IR photography, probably I'll get a cheap camera to convert. I read that canon/nikon lenses are not good as they try to 'disperse' ..

I want to try on landscape as well as portrait.
For landscape I like the feel of blue (sky) and white colour (grass/trees)

Whereas for portrait, I like the 'anime' kind of colour and look

how is the picture look like directly out from the camera (720nm)? I read that in PP they'll swap red with blue ...and other alteration..
hmm

Striaght from the camer will depend on the camera and white balance - on an Olympus it was easy to just set the WB to 2100K and they'd come out as above (but with red and blue channels swapped), with my current panasonic it was a nightmare to set up a white balance, normally the images are just like black and white but shades of orange and red (with AWB), the norm is to take a custom white balance from some sunlit grass but that was only partially succesful with my panasonic. AFAIK it works fine on Canons doing it that way. My final method was to take the filter off, and take the custom white balance from a dayglo orange sign, which seems to have worked ok, but not a patch on my Olympus. I am considering a GF1 to have permanently converted to IR but can't afford it at present. :thumbsdown:

For the record, all Zuiko lenses seem to behave fine in IR, but older single coated OM fit lenses aren't as good (they are very flare prone and lacking in contrast).

Oh and it may be worth mentioning that ND filters are useless in IR too. (y)

Please, please DO NOT use Protech to convert your camera! I know they're cheap, but there's a very good reason for that - they're bloody cowboys!

I sent them a brand new, straight from the shop Nikon D40 to convert and after over a month of excuses they finally admitted that they'd fried the main circuit board on it whilst attempting the conversion.

To be fair they did offer to get me another new camera to replace the one they'd destroyed, but what the sent me was an old refurbished one with nearly 4000 actuations on it. When I complained about this I was told they had bought the camera NEW from Warehouse Express and that is how it came, an email to WEX, however, confirmed that, yes, they had purchased the camera from them, but that had been a faulty customer return and that Protech were well aware of this.

To make matters worse there was dust UNDER the the filter - any shots taken at an aperture below f/11 looked as if the camera had measles...

Eventually after a lot of hassle they gave me my money back (plus the cost of the camera they destroyed) but I noticed the day after I returned the camera to them it was up on Ebay, with no mention of any of it's history.

Next time I'll be paying the extra and getting ACS to do the work.....
 
hmm, Flash in The Pan,

I've been a customer of yours
can you provide ACS email etc?? how much to convert?

I'm with Canon's system therefore plan to get a cheapest slr to start my IR journey..:)

sorry for your bad experience with Protech. Maybe you are the unlucky one..
well at the moment, i need to know my budget on getting into IR game
 
Right just for info, the portraits were taken with a 680nm filter, I've just got one and that's the same false colouring I'm getting. Note though, that with that filter you don't get the white foliage effect, they're more like tinted silvery colour so if you want to shoot both types, then maybe a full spectrum conversion on the camera and a lens filter to distinguish the effect would be the way to go.
 
Excuse the lack of focus or sharpness, very quick snaps to show the colour differences:

Traditional 720nm filter (Neewer equivalent of R72)

Unbranded 680nm

Both straight from camera, Custom white balances are set for each, otherwise you get monotone magenta from the first and monotone orange from the 2nd.
 
Don't be fooled into thinking it lets all greens through though, my car is dark green with a slight blue tint:

GH1, Zuiko 50mm f2.8 ISO 1600 and 680mm filter, straight from camera.

ACS - just to be clear, I haven't used personally used them...yet
 
i used advanced camera services for my nikon D50 conversion, i chose them due to quite a few glowing reports i read through google searches. their estimated return date is about 8-10 weeks but i had my back after 4 as the "Nikon man" had a window open up for mine :D

i went with the 720nm filter as it was recommended due to me as i already had been using the cokin p007 and hoya r72 filters and is suppose to give a similar result.

i can't adjust the white balance enough in camera so my review screen is effectively pure red, i use the histogram to make sure the exposure is okay, on the computer i select my white balance to grass or leaves to give this effect

then in GIMP i use channel mixer (i think to switch the red and blue channels around)

can't wait to win the lottery and get a 5d2 converted.

Thanks Alan,

Picture right out from the camera made me feels like I'm a colour blind..lol

What kind of tweaking did they do?
because from what they did like
http://www.flickr.com/photos/jamiemckerral/4004854207/in/photostream/

Seems to be green become white colour..
blue is royal blue...

That'll be colour reversed. Things that reflect IR will go white, with a hint of blue or red. The sky will generally go very dark red, so you colour reverse it to go blue. .
