As a birthday present, my partner surprised me with a trip down to Hobart, Tasmania for the weekend. A big part of my present was that I could spend as much time as I wanted taking photo's without any pressure to hurry up. What a great gift! I definitely made the most of it, and took a lot of shots. I've am planning to have them all printed in one of Apple's Photo books, so when that arrives I will let you all know how it turned out.
On the Saturday, we drove down to
Port Arthur, the site of Australia's largest (and most brutal) penal colony from 1833 to the 1850's. Pretty spooky place, there was a lot of history there, and with icy conditions, and strong winds, it put an exclamation mark on the already unbelievable atmosphere.
I took a few
High Dynamic Range (HDR) shots over the day. The theory behind this is that you take 3 photo's (or in some cases, create three different exposures from one RAW file), one shot correctly exposed, one overexposed and one underexposed. This way you manage to capture all the detail in the shadows, while also capturing the detail in the highlights. If you were to expose only for one or the other you would end up with either black shadows, or blown out highlights.
This is an example of three seperate images, the top overexposed by 2 stops, the middle exposed correctly, and the bottom image underexposed by two stops.

I then used a program called
Photomatix, by HDRsoft, to combine the three images. There are
plenty of
tutorials on how to do this
manually, however I quite like the effect that Photomatix produces. You have quite a lot of control over a range of variables in Photomatix to produce a subtle HDR effect (which I prefer) or a more dramatic, cartoon like effect, that is quite common on sites such as Flickr. Below is the control panel, and the same image, done with the cartoon effect (which I am not so fond of).

Finally, after a little further sharpening, and level adjustments in Photoshop, the final image looks as follows:

As you can see, this retains all the detail up in the clouds, whilst also capturing the fine detail in the grass and stonework. It captures the whole dynamic range.
A few other examples from the weekend.
