One More From Yesterday

I want to tear down one other image from yesterday morning. Like the others, the final image is a five file HDR composite. This one, though was zoomed all the way out at 24mm to get the clouds and their reflection in the water where the Mohawk River meets the Hudson River.

The 24-105mm lens at 24mm does have a bit of corner vignetting and the HDR processing amplifies that quite a bit. Normally I just use the RAW files from the camera in the HDR software but for this I first corrected for the vignetting in Canon software and saved them as TIFF files for the HDR processing.

This first file is the normally exposed scene prior to any lens correction:


24mm, f/5.6, 1/180 sec., ISO 100

Here is the same file after correcting for lens aberrations including distortion:




Here is the five file HDR processed end result using the Painterly 2 presets on Photomatix Pro:




Here's what the image would look like without correcting the RAW files first:




Finally, the geography portion of the post. This cropped section of the image shows Peebles Island, Waterford, Saratoga County in the foreground. The sandy beach is on the tip of Van Schaick Island, Cohoes, Albany County and the shoreline on the left is mainland Troy, Rensselaer County.

A Late Start for August

Part of the reason for a late start to blogging in August is the demise (mostly) of my 2010 MacBook Pro. At the end I had to use a mouse and a USB keyboard to do any work at all. The replacement 2015 MacBook Air has the same RAM and storage size but it has a faster processor, the storage is an SSD rather than a hard drive and the screen resolution is 1440x900 rather than 1280x800.

The new computer processes photo files noticeably faster and has USB-3 ports which will transfer files much faster. A Thunderbolt to Firewire adapter lets me use my firewire drives without having to resort to their slower USB-2 alternative connections.

Today is the first chance I've had to process files on the new machine. My walk over to and around Waterford afforded the material. My 5D Mark III and 24-105mm lens were the capturing tools. The new computer and Photomatix Pro software were the processing tools for five file HDR images.

Foggy HDR Composites

It was a nice foggy morning for my walk around Waterford today. Here are some HDR shots. Keeping the text short to include more images. The usual 5D Mark III and 24-105mm lens.
