Example of HDRtist

Thursday, April 29th, 2010

Here is an example of an HDR photograph assembled using HDRtist. Here are three reduced size original images (taken at Raglan in Monmouthshire in the UK). The first one is the “normal” exposure, the second is one stop underexposed, and the third is one stop overexposed.

Image at Raglan Castle — normal exposure Raglan Castle — one stop under exposed Raglan Castle — one stop over exposed

Here is my output from HDRtist from these three superimposed images tonemapped to provide this.


Long time with no posts

Tuesday, April 27th, 2010

I had every intention to keep this weblog active with at least a post a month and preferably more than one each week, but pressure of work got the better of me.

There have been a lot of things that I have wanted to write about. I’ve recently discovered HDRtist, an amazingly easy High Dynamic Range (HDR) application for the Mac that is free. It is very simple to use with essentially just one control and can combine multiple photos or even generate pseudo HDR images from a single raw image. I will post a couple of my examples soon.

I’ve also been exploring personal finance software. As previous posts have noted, I’ve been sticking with gnucash on Mac OS X largely because I’d used it for a long time on linux, but it is hard to compile on Mac OS X (actually, its hard to compile on linux as well) and while there is a ready compiled version available at Source Forge, it has some limitations. My current strategy is to get my gnucash data as clean as possible and then try to convert at least the last few months to iBank. iBank appears to support the features I need, and although some previous experiments found some flaws, it seems the most suitable for my needs.

I’ve still not upgraded this MacBook to Snow Leopard. This is largely because of a few legacy programmes that I’ve used in the past for storing passwords and application serial numbers. I’ve been using 1Password for a long time, but still have a few passwords stored elsewhere, and some old serial numbers scattered about. Once I’ve done this clean up I should be able to upgrade my MacBook. Although it is over three years old now, in some ways my MacBook (2GHz Intel Core 2 Duo) is my most powerful Mac computer. My iMac was an original Intel Core Duo, and my Mac Mini (bought at just the wrong time before a refresh to the mac mini almost three years ago) is also only a Core Duo machine.

Hopefully I’ll keep the posts coming now. Even if no-one reads these ramblings I find it quite therapeutic to jot them down.
