Does anyone have good experiences with the XT Rebel and using Infrared filters?

I have also heard that stacking an Infrared filter with a #25 red can produce good results.

Any comments on using the dSLR with Infrared filters would be appreciated.

ooo ooo... good post! I'm planning to buy an IR filter this weekend.

Well I'm using a Hoya R72 with my 300D, if it works quite well with it I would think it'll work just as well with the 350D

What added benefits can be achieved by stacking? I've never tried IR, but am excited to give it a try... counting the days... I have already looked into the Hoya R72 and I think that's what I'm going to get.

I curious to see some results. There was an article in Popular Photography recently that noted you could use the 350D's built-in color filters in B&W mode to simulate in infrared effect, but I haven't tried it yet.

horrible luck with the 20D! I bought an older Sony...just perfect. Check out my IR pics on the link in my sig.

How would you do that? (I'm still learning my XT)... I've played around some with built in filters a little and B&W but haven't really captured anything close to IR... I'm guessing the RAW image would require some heavy post processing. Insight?

The 300 and 350 both can do IR very well BUT you will be dissapointed if you are using the KIT lens, There is a fairly "large" IR hole in the center of the glass elements (most cheaper glass will have the same problem) so what happens is that you get more IR in the center than on the sides...so much like an over exposure... you will often see "white" halos in the center of your IR images, bassically it's a IR blowout.

Exactly what I got with my 20D.... I think they are more like "hotspots" on the glass. Just made for poor photos, and the long exposures didn't help any at all.

Do you have a lens recommendation... I just bought the camera and my wife hasn't completely forgiven me yet so budget is a bit of an issue. :-)

The 50mm f/1.8 is said to work great with IR. And it's cheap as well.

If you are really interested in IR, get your paws on a 20Da. The "a" standing for astrophotography. This special edition 20D has reduced IR blocking and some other enhancements specific to astrophotography.

uhm... would love to but I just purchased my XT Kit... I'm pretty new to photography and would like to ease myself into it. I have an interest in IR and am looking to buy a filter this weekend and maybe some glass... not a new camera. Do you have any less bank breaking suggestions?
 08/11/2005 10:42:57 AM · #16
The problem with IR lies 100% with the lenses... the cheaper the lenses the more problems there will be. Bizzarely, not ALL 18-55kit lenses show the same amount of problems, another sign of "cheapness". Some Kit lenses perform acceptably and others have a "whole" that covers 1/3 of the lens.

There are a lot of good "affordable lenses"

the 17-35XrDi and the 28-75XrDi from Tamron offer spectacular glass quality and are very affordable.

OK... here's the plan...I'm going to Wolf Camera this weekend and plan on buying the Hoya R72 to try with my Kit lens just to get a feel for IR... From what I can tell on this site all advice points to "if you buy glass, buy good glass" I found the 28-75XrDi on B&H for $400 which although "affordable" is out of my reach considering the $1200 I just dropped 3 weeks ago for my kit. I will wait and save for a better lens (maybe Santa will be good to me). I can't find the 17-35XrDi however.

Just a few follow-up questions
1.) Do you have any input on the "stacking with a #25 red" suggestion earlier in this thread?
2.) Am I wasting my time with this approach or is this a good way to wet my appetite for IR?
 08/11/2005 11:54:30 AM · #18
I don't see how adding a red filter will intensify the IR frequencies... the range is really not the same. If you want "serious" IR effects, you can buy a #83 or even go nuts and get a #93 IR filter... they are much darket so you'll need to make longeer exposures but the effect is improved.

VERY IMPORTANT BAD NEWS: Here is another piece of extreme bad news for you... your lens (the kit) is, I think a 56mm... and you will buy a 200$ filter to put on a 100$ lens.... The bad news is that Quality lenses are 77mm and this means that when you upgrade.... your filter will no longer fit on your new glass....

SO if it is your intention to upgrade... don't by a B&W or a Hoya.. but get yourself the cheaper (yet pretty cool) Cokin filter...at about 35$ you won't feel bad when you'll trash it for a 77mm B&W.

I think he was misstaken and meant this lens.
//www.bhphotovideo.com/bnh/controller/home?O=productlist&A=details&Q=&sku=303166&is=REG&addedTroughType=search which is fabulous for the price, but more expensive than the 28-75.

Thanx Kybosh, I'm sorry for the mistake.

Ouch, you're full of good cheer aren't you! I knew I was getting to an expensive hobby, but holy crap. Thanks for the valuable information!!! My kit lens is a 58mm and I priced the Hoya at just under 50 on B&H. I figured that was fair to experiment with if I could get the same price or comparable at Wolf (since I'm going there anyway).

I think you just talked me out of experimenting with IR... It was going to be strictly for fun anyway. Maybe I'll just get a better lens. (off topic) Suggestions on something for landscape photography?

I really think that for 50 it's worth the buy...if you have a folliage rich environement, it can be a lot of fun. the filters do get expensive when you get to the 77mm size (from 50 to 200 !!). I think that regardless of the lens...you would enjoy it.

Thanks again for all the information... You guys are great!!! I live in South Carolina and we have plenty of green. I'm interested to see the live oaks with Spanish moss in IR... I think it'll be an interesting effect. Anyway, I'll keep you posted on what I decide to do after this weekend.

In case I do decide to go with a lens instead, what should I look for? My profile (Places) is the kind of photography I prefer. Landscapes, etc.

Wide angles are great for landscapes, again the 17-35 from tamron will make you very happy and is quite affordable.

Regarding IR, the thing that reflects the most IR is Chlorofil, the more a tree is "healthy" the more powerfull the effect, you'll need a lot of sunlight, and you also need to make sure that the sun is directly behind you in order to get the most dramatic effects.

The Tamron 28-75 and the very popular Canon 70-200 f/4L both have a 67mm thread size. If you plan on buying those lenses (my favorites) in the future, you can get a 67mm IR filter and a cheap step up ring. That way, you can use the filter now on the kit lens and won't need a new one when you move up to better lenses later on.
