Have you ever asked yourself why those photoless days – the cloudy ones, are so diffused and blue?” Probably not, because it seems to not be an important question to ask yourself. Unless you’re me. I love deep-diving the trivial things, it seems.
Blue light scatters, and red light is absorbed. Actually, some blue light is absorbed, and some red light scatters, but it’s more often the other way around. So, on a bright sunny day, all the light comes from one spot in the sky, right? But on a cloudy day, it seems to come from every direction. That’s because it IS coming from every direction, as a result of scattering. When you take the red and yellow out of the color spectrum, what is left? Well, green and blue are what remains – but it’s the blue we mostly see, because there’s not much in the clouds to reflect green light. Water reflects blue light pretty well. So, now you know the answer, and I’m sure you feel much more fulfilled.
Photographers hate cloudy days. With the red and yellow all being absorbed, what is left is mostly scattered blue, and only 1/3 of the pixels in the photographer’s camera can catch blue light. So, the camera sees 1/3 of what it could see on a sunny day. No wonder the cloudy day pictures are dull and uninteresting.
Figure 1: Nature made a surrealistic sculpture, awaiting my lens
The photo in figure 1 is of water swept grasses. Click it to see it in full size. Nature makes some very pretty stuff by accident sometimes. Lovely to be there to catch it.

Figure 1 : Bee shot taken with K5, Pentax 50mm /f1.4 vintage lens
Recently I started to take macro tube shots of bees in my area. This is quite an addicting facet of photography, I must say. I’m a rank beginner at this task, but so far have managed a few semi-interesting shots. The picture in figure 1 is one of my favorites thus far (clicking on the photo will show it enlarged on smugmug).

Well, I kick-started my photography hobby for a second time recently after a hiatus of about 37 years. I bought into the theory that I could populate my lens arsenal with vintage stuff and save a bundle. In short order I had over a dozen lenses in my possession, none made after the date they want to check on driver’s licenses in order to purchase hard whiskey. Some were made not only that many years ago – but multiples of that many years.

Figure 1: Just one of those photos that needed more space
I’d been dabbling in the realm of photography for the past couple years, after a hiatus of almost forty years. I wasn’t a very knowledgeable photographer back in the eighties, and really have only incrementally added to my repository of things to know in this realm of photography.
Most blog sites are (well, of course they are) – meant to be more for blogging than for photography. I finally realized how tiring it must be for viewers who can’t really see my photos in high detail – due to size or layout or navigation restrictions, all the while I talk or write about those photos. Subsequent to this epiphany, I set up a photo repository (on a photo site designed specifically for photos) in order to remedy that situation. Don’t get me wrong – this blogger platform is great for blogging, but for photos it works in a more ancillary mode. The platform is more versatile if you want to run your own server, but I’d rather take the site’s photos, rather than worry about its security setup.
Technically, I could switch to another theme more suited to the photo. But in that case I’d lose the nice textual format that is the mainstay of the blog. It’s a bit of a catch-22. Anyway …
I started with a Kodak Brownie in the sixties, and eventually bought an enthusiast’s level Olympus film camera. Later, when the film process became too complicated, I bought one of the first digital point ‘n shoot Kodaks. I kept shooting my casual pics with that style of camera throughout all of the intervening years, but such casual shooting doesn’t necessarily qualify anyone as a photographer or improve their game. The whole idea behind such a consumer camera is that one can know absolutely nothing about photography and still, at least some of the time, take reasonably usable pictures.
So, my latest adventures are blessed with more disposable time, and boy – can learning the ropes of the photographic arts dispose of quantities of that! Whilst I learn, I hope you can enjoy some of my stuff, as posted at the above referenced link.
Figure 1: Homemade “DIY” power adapter for Sigma SD14
I really have come to appreciate the Sigma SD14 camera that I’ve been using for over a month or so, applying it for IR photography. It really shines there, due to the Foveon class sensor that outdistances most competitors in terms of IR sensitivity. I have captured time-lapse photos that I believe contain as low as 1.5 microns (high mid-infrared) wavelength light. This is ordinarily not possible with the standard Bayer sensor in most camera brands, based on the info (veracity unknown) – that I’ve come across in my internet meanderings.

Figure 1: An unexpected explosion of infrared on my dry erase board.
Is there such a thing as an infrared bomb? I’m hard pressed to explain the picture in figure 1, one of the first infrared photos I’ve taken with the SD14. I had just taken the shot in figure 2 (a photo of me looking like an infrared zombie) – and had gotten up to check the camera. Without touching the tripod, I snapped off another shot of the dry erase board that hangs on the wall behind the chair I had just vacated. The photo of figure 1 emerged as a result.
