thanks

To specifically anwer your photos, yes, but very but it is very limited.
There is a filter on the sensor to block out IR. This filter can be removed, but you will need to have on the filter when you would want to take normal pictures.
With a red filter, or other UV photography aid filters it can be done with some positive results.

hey obi, have you tried doing any IR photos with your 20d? as you know i'm pretty into IR and i've had some good results with my unmodified 300d. i was just wondering if canon uses the same IR blocking filter in all of their recent d-slrs.

Apparently the 20D is not such a great IR camera, this is based on many threads on Fred Miranda. I have no personal experience with it, but others have stated that a lot of photoshop was necessary to bring the image up.
What do you use to get your IR pics, just a filter?

This won't be of much help if you already own the 20D, but you know that Canon has the 20Da (in Japan, can import) which is better in this respect.

i just use filters. Hoya R72 screw in type and a Wratten 89b gelatin for the fisheye. as i've mentioned in previous threads, post processing is almost a must with any camera that isn't modified for IR or isn't 3 years old and having a weak internal IR low pass filter. it's hard to tell if the people who said the 20d isn't so great for IR just didn't know what to do with the out-of-the-camera images, since my 300d isn't known to be great for IR either.

Wow! Those are really beautiful! One day maybe I'll try that too with my EOS 350D. :D

Totally cool, TeddyLoves! *thumbsup*

Very nice. What did you use to color them?
What was your workflow on these pics?

Those shots are just awesome Teddy. Thank you. What is your work flow? I'm told you need really long exposures and since the camera can't focus through the filter, you need to pre-focus. What kind of post-production work do you do on them?

(Ha - Juan - for some reason I didn't see your post before I did mine. :p)

I am going to give IR a shot. It looks like a lot of fun.

Teddy, just out of curiousity, did the images come out of the camera that way, or is it just your particular "flavor" of post processing IR? i'm NOT asking you HOW you post processed if at all, because the last thing we need is a bunch of people copying a certain style. do your images come out of the camera completely red and magenta if a custom white balance isn't set? it's not a modified camera is it? sorry so many questions - i like shooting in IR as well :)

Obi: that would be pretty cool if you got into IR too. maybe we could get an IR thread going in the gallery, and get some new stuff out there instead of all the same IR look/themes that are already all over the internet.

I wouldn't mind doing some blended IR and regular pics. Perhaps having the subject or model exposed under regular light and the background with IR. It could give a surreal look. This would be easier than Photoshopping it.
Now I gotta go get the filters. How much would they be in 82mm size?
Haha

have you seen the prices for Hoya IR filters above 67mm? they're ridiculous!
if cost is a concern, tiffen filters don't triple in price above 67mm like the Hoyas and wratten gelatin filters are worth a look too but are a pain to use. though keep in mind that the tiffens allow different wavelengths through compared to the Hoya.

i custom white balance with green grass to make sure they come out white. if not, the images will come out deep red.
but that's only with the jpeg files. custom white balance dont matter with raw files. i do CWB only because i shoot RAW+JPG so that i can preview JPG files. but from my experience (3 weeks, not much) most of the time now i can tell what the exposure should be.
i only take the filter out for composing/framing, not for focusing because it still focusable when the filter is on.
after that, the work in photoshop is another story, and it is completely at your taste.

@TheObiJuan: recently i find myself always shoot twice. one with the filter off and one with the filter on. sometimes the scene comes out nice as normal color, too. and another reason is, like you said, i have a normal version so that if i want to blend it with the IR version, i always have it. imagin something like, a red car, parking under a really really green tree, and the grass is green also, and i make 'em into IR, and the car remains red. and the sky is still blue (the blue look of IR or the normal blue look, depends) isnt that cool? sometimes i can even mix the colors together, for example, use only the color of the normal version, change into Color mode and blend it into the luminosity values of the IR version, then adjust opacity ... or we could use layer mask to blend the image so that it slowly changes from IR to normal or normal to IR ... etc ...there are just thousands of posibilities we could do with IR shots.

Here's the Hoya Infrared filter page from Canoga Camera. They seem to have pretty good prices. Click on your filter diameter in the table at the bottom to get the filter for your lens.

http://www.canogacamera.com/e/env/0001ZbUD0cIZtTgWzQ2k5i4/thk/catalog/h/004spe.html?link=040inf.html

So for instance, a 58mm IR filter is only $48

Hi.
I was just wondering I have a 300D and would like to get into IR photography. I have read reviews though that said it doesn't work with this camera.
So I thought "daangit" anyways would like to see some of your sample pictures and if you could explain how you got them aswell would be great. :D
do you do any editing in a program etc.

Wow, this thread is old. :)

Congrats on having a DSLR and wanting to get creative with it!
The best approach would be to have your 300D modified for IR, but this would make it mostly impotent to take normal spectrum pics.
You could buy the IR filter by following the link above to Canogacamera.com and then mount it and shoot away.
You will notice with the filter mounted the world looks a lil' different.
Feel free to experiment with different white balance settings to get the look you want.
Do you shoot in RAW? Do you own photoshop or lightroom?

Yes I know you can modify it but as you say it's pretty much impotent to normal photographs, I would still like to use it normally and frankly I don't have the money to have two DSLRs.
I'll be looking into it some more but it is always nice to know you can use the product before you buy it etc.
I have a small memory card therefore at the moment take photos in JPG's highest quality. If I have it on raw I can only take 6 pictures but I will be upgrading my memory card because I'd rather use raw, and I have Photoshop.

I'm new to the forum and was researching Infrared photography and found this place.
