New Digital Camera Technologies
Most new digital cameras come with sometimes remarkable but predictable new features...more resolution, better anti-
As I write, there are at least two sources of light field cameras. One is for commercial use and the other is aimed at the causal photographer who didn’t want to know anything about focus anyway.
The Lytro camera company is selling the consumer model for $399 or 499 with more memory.
The company website gives you a good picture of the camera and its current features. They also have sample pictures that give you an idea of what you could do with the camera. This camera, in its present form, is not going put Nikon and Canon out of business, but version 2 or 3 might have them worried.
The commercial use light field is made by a Germany company: Raytrix. This company produces several models with various features and resolutions.

Stealth Developments in Digital Cameras
By paying attention only to what things are called and not to what’s really going on, we sometimes don’t notice significant developments in fields like photography. Something that’s crept up on us is the increasingly capable cell phone camera. When these first appeared, there was little worry that they would replace “real” digital cameras. The picture was low-
What these cameras still lack is an optical zoom lens and there is a little more “shutter lag” than with a conventional digital camera. They probably won’t satisfy a serious photographer looking for the great photo that will be the prize of his collection, but for many routine uses, they get the job done and are the camera of choice because it’s the camera you have with you. The picture on the left is a cell phone shot taken at a Ferndale, Michigan street fair.
A tip when using a cell phone camera: make sure the lens is clean. The lens is so small that it is easy to forget about it, but, because it is small, it is easy for it to fog over and collect so much dirt that the picture looks like it was taken through a fog bank.

A Guide to Post Industrial Detroit is Theresa’s first ebook that was composed and written as an ebook (not converted from print). Here’s what she has to say about the book:
This book is a guide to the real Detroit, with its natural assets like the riverfront and its many beautiful buildings, as well as its abandoned neighborhoods and "fabulous ruins."
My interest in Detroit and its history is personal. I came to Detroit in 1963 to attend Wayne State University where I met my future husband, David. In 1967, we were newly-
In the book, I share my observations, stories and photos of my adventures as an urban explorer in a city I and David have known well over 45 years.
The book covers Detroit's past and present, with plenty of facts and stories about neighborhoods, buildings and the changes in the landscape of the city over time. The narrative, which takes you from the Woodward corridor, to the East Side and the West Side, is liberally illustrated with photos (over 190 photos taken by Theresa and David Welsh), plus links to more photos and commentary online.

Our first eBook is a collaboration between the writing of David Welsh and drawing by Amy Welsh, his daughter. It's a quick and funny read with a bite, chronicling the biggest oil spill in history as a child might understand it. All of the events it describes are true and all the characters are based on the real people...which is why they are so funny...if you have the right point of view.
There are fifty pages of text and cartoon style illustrations that we are betting will be worth your time and money. One thing is sure, there's nothing else like it.
