I awoke at 5:34am and remembered an email from a few days before. It said the space station was to pass over my region starting at 5:38. When I got to the front window, it was high overhead moving toward the eastern horizon.
Looking to the southeast I found Mars in Scorpius. It had moved from its position the morning before. Here depicted by The In-The-Sky.org Planetarium of Dominic Ford. Being only 13˚ F this morning, I opted not to go outside for my own photograph.

There are many examples of black and white images with color added afterward. A fellow blogger has beautiful ones here. The techniques have been around since the first daguerreotypes of 1839. Hand coloring with pigments and dyes brought new life to the monochrome images before 1900. New 3-color techniques of adding color to images came about in the late 1800s. The more recent advent of digital photography allowed images in color without the need for film and chemicals.
My interest in photography goes back to the 1970s. I became interested in the desktop computer in the 1980s and bought my first Apple Mac in 1987. I moved into the digital camera realm by 1999. One could import the digital color images into the computer and manipulate the colors at will. It was great fun. A huge industry is built around color manipulation of images by the likes of Adobe Photoshop and other programs. Our phones can even do amazing things to our color images.
I was given a book last year called Mathew Brady and His World. It describes Brady‘s work from his first studio in 1844, his Civil War photographic experience, and includes photographs of many notables of the era. His black and white work was remarkable. I wondered how some of the photographs would look if they were in color.

The new camera I got this spring has many new useful features compared to my previous camera. One feature new to me is shooting images in RAW format. I wondered what difference it made in the image quality.
I conducted a simple experiment and photographed the same scene in AUTO mode and in RAW mode. For both modes, I used a 10 second timer delay to eliminate movement. The camera was at full optical zoom of 65x on a tripod. The subject was a radio tower visible from my house 100 m (330 ft) tall and 500 m (1640 ft) away.
This first image used the camera AUTO setting. The camera automatically processed the image in a variety of ways such as shutter speed, ISO, contrast, brightness, white balance, etc, and saved it as a JPG format on the memory card. That resulted in an image needing less memory space and which is generally pleasing to the eye. Click on it to embiggen to full size of 4608 x 3456 pixels.

It seemed like a good thing to do. You get a new toy like that and try to shoot something with it. I chose the Moon as my first target. It worked perfectly. Take a look.

A previous post of mine was on the topic of the Camera Obscura, a forerunner to photography and camera technology. Our granddaughter used the idea to create a project for her school science fair. She obtained three images which were excellent examples of her results. As a proud grandparent, I get to boast.
Camera Obscura is a simple device consisting of a light-tight box with a hole in one wall. The hole allows inverted and reversed images to be cast on the opposite wall. The box can be small or as large as a room. The image below is the basic idea. She used her bedroom as the box.
