tibook acting strangely

screen_cap.jpg

Strange things are beginning to happen to my old TiBook. Three years old this month and it had never really been turned off, so it doesn’t owe me much I guess. I took this screen capture after it awoke from sleep and behaved strangely, and surprisingly enough the weird pixels were captured, which I was surprised at. I think that this may be important in tracking down where the problem might lie. I’ll have to head off to Apple Discussions for a read.

Gilding the Lily

This is a composite of a colour and infrared image. The camera was mounted on a tripod, then various bracketed exposures of the infrared image were taken, followed by a colour image in the same position. I chose a well exposed infrared image and combined it in Gimp with the colour image using overlay.

Because of the long exposures in infrared, I’m getting some weird noise artifacts and occasionally dead pixels. I thing the Ixus does a lot of processing internally when it takes long exposures to reduce the amount of noise, and it’s for this reason that I’d like to experiment using RAW format, which my camera doesn’t do.

infrared and XP2 redux

I suppose I’m a little despondent about the digital IR results to date, but there again it’s early days. Seeing that the old Yashica will be fixed sometime in the near future, I wonder what results I’d get if I loaded it with XP2 and used the Hoya R72.

Thanks to Rob Novak for showing me why this idea won’t work

XP2’s response drops greatly after 630nm, and has virtually no response to wavelengths below 660nm. The R72 filter’s transmittance curve doesn’t even start until 700nm, reaching peak transmittance at 750nm.

Tracks in Wheat 

This one is doing strangely well (for me anyway) on Flickr. I uploaded it sort of as a joke because it’s so like a photo by a photographer I admire called Catherine Jamieson from Canada. Click on the image to go to Flickr and all will be revealed.

Seeing that the old Yashica will be fixed sometime in the near future, I wonder what results I’d get if I loaded it with XP2 and used the Hoya R72. The Yashica also has the advantage of 28mm, 50mm and 70-210mm lenses. It will be interesting to see. I wonder if I can get into the grounds of the bowling event in Dun Laoghaire in September so that I don’t have to shoot through the fence. Although I suppose the fence gives credence to the perception of elitism around this sport in Ireland.

Hmm.

There’s always the bowling green in Herbert Park. I need some good light.
