    Fascinating, IR filter on Santa's list. Thank you for some food for thought.

    Re: Introduction to affordable IR Photography

    This excellent thread has gone a bit quiet so I hope you don't mind if I post a couple of non Oly pics from today. The first is the straight shot, f8 at 1/3000 I think. the next is the IR through a 760nm filter. 1/45 at f4 (may have been f2.8). Both pictures have simply been converted to jpg from DNG and changed to greyscale, then downsized and exported in from Lightroom. No other tweaking involved.

    The first thing I notice is how much less sharp the IR picture is. I doubt if the camera shake was a factor as all the IR pics are similar and the lens is certainly not underperfoming at f2.8 so is the poorer quality implicit in using IR or down to the filter, just a cheap chinese ebay purchase.

    Secondly, the topic doesn't seem to suit IR too well, what are the factors in choosing a good subject for IR?

    It's odd that I have a seagull in about the same place on each picture, bit blurred on the IR version due to the slower shutter speed.

    Filter is here will go out tommorrow weather permitting. Need next installment to know what to do once I have images in camera. How do I process them?

    I'd check, but I think the G1 may be more sensitive than the E-3 for IR, so that may work even better (plus contrast AF is great for IR photography!)

    Good point, Andy, but I was itching to use that new lens!

    Not a bad start, John. Of course you picked the wrong time of year to start doing this as leaves on the trees are a great subject for IR. I can see that the branches were moving around during the exposure too.

    Raring to see more!

    Went out to play with two new toys today, the 9-18mm lens and an IR72 filter. Here's my first composition.

    The colour version

    The processed IR B&W conversion

    The unadjusted (apart from resizing) JPEG using the IR72 filter

    I'm sure that some of you can process a much better version than me. Feel free to have a go if you wish.

    Any comments and advice on my own feeble attempt will also be appreciated!

    Thanks.

    Only John (the other one!) can really answer this, having used the Chinese cheapy himself, but I wouldn't expect it to be a problem.

    There's bound to be some degradation, in theory there is with any filter, and, let's face it, the optical quality of the glass is not going to be the best in a cheap filter. However, you'd probably have to pixel peep and if the IR effect and composition are spectacular enough nobody's going to notice.

    Don't forget, some photographer's manage to regularly produce stunning images even using Canon lenses....

    Nice one Dave, not sure we're going to have any decent weather this week. I must check the forecast...

    I have an E-1 and an E-30 so it will be interesting to see what the differences are.

    great informative thread, it might just inspire me to dust off my IR filter and give it a go. i read somewhere that the e30 has strong IR filtering, so i will try my `510. it should yield better results
