Autopano by Kolor vs Autodesk Stitcher

E-mail Print PDF

San Marco Square Little PlanetA few years ago I purchased a product called Stitcher by Realviz.  This product was sold to Autodesk and updated further (and split into a vr tour application as well.)  While Stitcher still seems to win out over most competitors by any number of factors, new entrants are chipping away at its heels.

A Powerful Zoom Lens

E-mail Print PDF

A few months ago, I added an unusual lens to my bag, a Sigma 600mm F8 Nikon mirror lens.  Ebay photo of a simlar 600mm F8 Sigma lens for saleIt shares the same body conventions as other catadioptric lenses (ones that use a combination of refractive and reflective optics) which 'fold' the light coming into the camera similar to how a satellite dish collects a signal.  By reflecting the light twice (bounced from the rear element to forward one and back to the sensor) it achieves an economy of size that belies its reach ... comparable true glass lenses tend to be multiple times the size (length) of this lens.  Nothing is free however, and this economy of size (and price) comes at the expense of several stops of light.  Stuck at F8, this lens is practically useless in poor lighting conditions or without a camera that has solid ISO performance.

Mine is a fun olive green and was purchased from Columbus Camera Group, one of the many fantastic local camera stores in Columbus Ohio. When you buy your lens, be sure that it comes with the rear filters, or at least the neutral one of them as these are necessary for ensuring the lens captures the image properly.  

The first image below is a quick shot for context, taken of the roof of St Mark's basilica as seen from the Campanile (tower) in the Piazza San Marco.

Adobe Photoshop CS5 and the Content Aware Fill feature

E-mail Print PDF

Content Aware Fill is a truly amazing algorithm that can be found in the new version of Adobe Photoshop. It is useful both for spot fixes, as well as larger 'creative' fills.  In the example below, you can see how the 4 images of a panorama come together and leave borders, edges, and empty space.

Travel and Photography

E-mail Print PDF

This year I had the 'tremendous good fortune' to spend roughly the equivalent of three straight months in a car, driving approximately 25,000 miles.

That is equivalent to one circumnavigation of the globe at the equator.

iPad as a Monitor

E-mail Print PDF

I use a program called MaxiVista on my Apple iPad and my Sony Windows 7 laptop.  This application beams over monitor information to the iPad via my local WiFi connection, and lets me space out my working area on multiple displays. 

Technically, I'm using it as a third monitor, as I have a small Dell 15 inch LCD display from a few years back that is also setup on my desk for my laptop.  

Performance is acceptable as far as refresh / redraw goes ... video looks to run at about 5 to 10 frames per second (this means I can frequently type faster than the screen can update.)  

What is really amazing however is how much crisper / legible the display is vs the actual LCD monitor from Dell.  The iPad is brighter, sharper, and has the same resolution as my traditional external display.

Resolution and Megapixels - how to make your own D300x

E-mail Print PDF

I've been discussing some issues with the recent release of a new Sigma camera with some photographer friends of mine.  

This new Sigma claims a resolution roughly 3 times it's apparent sensor size, and some people are crying foul over this practice.  This is largely the same argument that's had about some of the Fuji DSLR sensors as well.  With the Sigma it captures each channel separately, and with the Fuji, it captures differently sized pixels of data and extrapolates that information.  This same extrapolation also is found in the Nikon (and I'm assuming Canon) universe, except that they sample certain colors (R, G, B) differently and interpolate the differences.

Mice, Trackpads, and Trackballs

E-mail Print PDF

I've been working on a virtual tour project for a client recently and am in the processing stage, where I take the Circular Fisheye images from my Sunex 5.6mm lens (NikonCanon) and process them through Autodesk Stitcher.  

I'm doing this on my laptop for some reason, a mind numbingly frustrating process where nuanced clicks to try and set the horizon lines within the images are interrupted by palm clicks and zoom effects from my multitouch trackpad.
