I was reading Photography Monthly (Sept 2005) the other day and they had a tut on Infrared pics from digital colour shots. So I thought I would have a go. I'm not sure if this really works. Opinions would be appreciated. Steve

I think the background way back there would be lighterif IR. I tried this a few times too and thought why buy a filter.Sure does show it in a different perspective.It is a good image for this.

it works very good for a software simulations... but some parts of this pic (light and shadows) looks as a negative shot... this is not correct... and the foliage must to be more white... a real infrared filter is a good choice! but for a software work looks beautiful!

I don't think I could make the difference to be honest but that's cos I know nothing of IR filters so to me, this looks spot on! But I think the opinion of people who actually use IR filters will be much more valuable here! I really like this nonetheless!

No expert on IR, looks good to me, I have seen several different ways to do this with PS/PSP, I agree the foliage would be whiter on real IR. My friend shoots a fair bit if IR and I have noticed on his shots how white the plant life is almost to the point of glowing. I know on some Digi cams the sensor has a filter to reduce IR, with the exception of the Canon 20Da which doesnt have one as it is for stellar photography. So if your camera cant see IR, I dont know if an IR filter would do anything? Richard (Onslow) was talking about this the other day on Zackos filters thread. Anyway I like this shot, the pillars look good, and there is also an IR tute in this months Digital photography user (landscapes) issue 80 Simon

Very cool shot but I agree with May that some spots almost look like a negative (ie. the tops of the columns). The tree on the left would be lighter too, and the background could use some slight lightening. Otherwise, a great software solution to IR. :) Here are 4 of my attempts at it: http://www.renderosity.com/viewed.ez?galleryid=861105 http://www.renderosity.com/viewed.ez?galleryid=856127 http://www.renderosity.com/viewed.ez?galleryid=834701 http://www.renderosity.com/viewed.ez?galleryid=830798

Pretty cool, Steve! When using an infared filter though...like May said, the foliage should be very white. Sure does make a neat effect though! :)

Thanks all. Will try again, not sure how to make just certain areas whiter, back to trying again. Steve

Your shot is pretty cool....
About IR, I did experiment it a few days ago with a 720mstr at 50% filter.
It is not so easy to have a good IR result. You need a strong amount of light to have a neat shot, elsewere the shot is blured.... Considering the sun direction, the angle of shot is also a factor of good result. The exposure setting is quite complicate because you can't read correct indications on your cam.. I used a speedshutter between 1 and 4 seconds... Without tripod it does not work.
