A good friend of mine took this photo a few days ago. Upon first glance, it looks like possibly an early morning shot. There’s mist on the lake, the sky is a pale blue, and the sun possibly isn’t quite breaching the horizon. Then you see the stars and the mind boggles. It [...]

I can tell from some of the galaxies… have you ever wondered just where exactly those awesome images of deep space from the Hubble come about? I always thought they where just images from a camera, but as it turns out, it isn’t quite that simple. Check out this video from the HubbleSiteChannel on YouTube where they show an accelerated look at the processing each image goes through.
Prior to 1990, photography was still stuck with basically the same technology that had been developed (get it?) in the early 1900s. Most of the effort in the photography world had gone into increasing the range and options for film. Because of this, photography could be a very costly and time consuming hobby. Then, in 1990, two camera’s arrived which would change everything. One was the Dycam Model 1, officially the first digital camera available to the public. The Kodak DCS digital single lens reflex (DSLR) camera was the second. When Techie sent me this photo I knew it had to be used in my photography series. Unfortunately, I failed to find a logical (or slightly illogical) place to use it. So, it’s the lede for today’s post. Which is really just a rehash of some comments in yesterday’s post. It’s Friday; I’m [...]
Once the process of taking photos started to be ironed out, people wanted to do more than stare at Oreo’s and wanted to see in color. Color photography actually stretches back to the mid-1800s. The first permanent color photograph was taken in 1861 by taking three separate black and white photos through red, green and blue filters, respectively. Then color would be added or subtracted, depending on the method used. Monochromatic Goodness After the inventions of the daguerreotype and calotype processes in the mid-1800s, the technology behind photography really started to advance. In 1839, English scientist John Herschel informed Talbot and Daguerre of a process to fix images by using silver halides rather than the mercury fumes they had been using. Probably a [...]  First photograph of a person. Watch your souls. Following the progress of technology can be pretty interesting. The camera obscura we looked at yesterday played a huge role in the development of the first camera photography. Up until the 1820s, the camera obscura would allow artists to project and image and paint it. However, our modern idea of photography is a photochemical process. That process did come along until Nicéphore Niépce created the first photograph in 1822 when he used a camera obscura to project an image on a plate with bitumen. The bitumen would harden as it was exposed to light and then the soft bitumen could be washed away. Exposure times were measured in hours and possibly days.  Illustration of camera obscura from a military design manuscript. Probably 17th century Italian The history of photography stretches all the way back to the BC era. In fact, the first method for capturing images is nothing like what we use today. It’s called camera obscura and stretches all the way back to a Chinese philosopher named Mozi who lived from 470 to 390 BC. In his writings, he described what would become known as the camera obscura calling it a “locked treasure room”. Not long after, Aristotle observed the same principles of the camera obscura whilst observing a solar eclips through the light image projected on the ground from the holes in a sieve. Euclid used the camera obscura as his basis for how light travels in Optics. Centuries later, da Vinci would describe the camera obscura in his works, and Johannes Kepler would use the term “camera obscura” the first time in 1604.

But Techie, they only look about an inch or so apart!?!
