Summer storms

Kind of a weird storm front tonight....





If you looked to the Northwest (above) there was a cool undercast to the sunset... if you looked to the West it was jet black.

Most of the big rain looks like it is going to slide just south of us again.  I will guess that we will get less than 1/2 an inch of rain even though it is being driven like a Monsoon with horizontal rain.

A warm Saturday evening in the upper midwest.

HDR 2 on Linux

Here is a slightly different version of same image....

This was created with Qtpfsqui

There is a little bit of a learning curve with this tool. I like that it allows you to work with RAW image natively vs. converting it to a format like TIFF or JPG. The particular filter that I used needed to be tweaked a bit as it was too wild for me.

I am still not completely happy.  I need some more time to bond with the tool.

HDR on Linux

I am playing with some HDR (High Dynamic Range) images on my Linux workstation.

This is not too exciting so far but it is my first attempt. Ultimately I used two exposures for this to get try to capture the highlights and the contrast in a single image.

I shot this in the field as 5 different images that are bracketed since I have not played with these HDR software packages. This initial image was made with "fotoxx".  I converted the raw images into Tiffs and then merged the tiffs. 

When time permits I would like to try this same photo with a couple of different software packages so that I can compare the results. Clearly the HDR approach helps take a noon image and make into something this is bit more appealing.

This image was captured in the area between Iron River, Wi and Port Wing, Wi.

Linux : Sync/Backup USB Drives

Here is an update to a previous post:

I use a 1tb USB drive for storing all of my images, application installs, virtual machines, source code for development projects, schematics, etc. I try to back it up on a regular basis (approx once per month) to a couple of other USB drives that are normally offline in storage. (Yeah I know... I need to rotate the drives through the safety deposit box at bank for an offsite copy...it is on the home DR list of things to-do.)

Here is the commands to make this process work with Ubuntu 10.4.

Example:
rsync -vrlptg --delete '/media/SOURCEUSB/' '/media/TARGETUSB/'

Real World:
rsync -vrlptg --delete '/media/Iomega 1TB HDD/' '/media/Iomega 500mb HDD/'

Command to compare hard drives:
df -h
