Review: depth-of-field is the area of the photograph that is in focus. A large aperture gives small depth allowing the background to be out of focus and the primary subject jumps out of the picture catching all of your attention. Small apertures give large depth, sometimes so large everything in the photograph is in focus. that puts your primary subject in its enviroment.

So, I've escaped my little doldrums. I've been researching and trying to shift my little photomind from film to digital. I found some advice that may [or not] interest you; photography should be fun. All the thinking about apertures, shutter speeds, film[digital] speeds, and composition, and the other things that go into a really good picture, fun should be one of the reasons we do it. To finally answer my phototeachers never to be answered question, "why did you take this picture?" Because I enjoyed taking it! Now I can get my 'A'.
That's the Rainforest cafe rising above the east end of the park, we eat there almost everytime we go. Try the 'Volcano' for dessert, you must leave room for it!

I'm Back
Now, I am looking for an excuse to be gone so long; let's see, alien attack? no, too believable, lost in the jungles of Brazil. No, I've been at work. Just flat out lazy? Can't be, everybody that knows me calls me other things [something to do with my mother and father not being hithched] but that's another story. Maybe its just I've been checking out some others web sites and, jeez this little place isn't but a snif. So to work out the meaning of life I'll just have to make more pictures.
Photonote of the day: When showing your pictures to others, it isn't what you show them, it's what you don't.

The Photobear loves trains. As promised, these are the other pictures at Epcot. They change the trains around periodically, and I like the steam engine. If you notice the big round things on top are pennies. That should give you scale of the engine size. That would be the 'O' scale, which is twice the size of the popular HO.

The Photobear likes trains. That simple statement can go a very long way to messing up your hobby like photography. So the best thing is to combine the two things. Here is the train at Heritage Park, located in McDonough, Ga. ( I-75 exit 218, go east about 4 or so miles, hwy 81). This train is a type similar to the one that ran over a washed away tressle back in 1903 or was it '06? 36 people died in the wreck, their bodies were laid out at the square, now they say the square is haunted. I don't really understand why a ghost would haunt the wrong place. Maybe they are as smart as we are.
This train is a 2-4-0, very similar to the type that opened America when the railroad began crossing our country.
This view is the last thing a cow sees if its on the tracks.
Photonote: the overcast day made the shadows dark so I set the camera to fill flash. The new automatics do this so easily, not like older cameras which required much calculation to fill, or you had to quess.
If you look carefully both driving wheels are linked together by a bar and that arrangement is rotated by the forward steam piston. How simple an idea.

Eeeww!! Giant bug!
I discovered this fellow hanging from my carport wall. At first, I thought what you did, eek! Then, I looked again and realized it was a skin of bug. (Bug: a creepy crawly thing with more legs than a dog.) These guys live underground for years and suddenly they all surface, shed their skins, spread their wings, which are under the skin, fly off, meet girls or a guy, have bug marriage, lay some eggs, and die. What has that to do with photography?
Why? that would be macro-photography. The technique of taking a picture of something small and making it fit the view screen. For this, I have a macro lens. Being the thrifty type, I spotted the lens in a pawnshop attached to a Nikon N2000. I really didn't want the body, but did want the lens. And it wasn't that expensive. I'll sell the body separately on ebay. I still have the body, it's a good unit, oh well.
I set the lens at 1:1.5. umm.....did everybody get that? No?
That is the ratio of image to object. The object (bug) is one and a half times the size as the image. Translation: picture of bug is real big on the film ( or digital medium) which allows us to see details we normally would not see. Look carefully, there are white net like fibers across the face of the bug, those are mold filaments.
Being in photography there is no free lunch, note the items that must be thought about before taking the picture. When shooting really close the depth of field (the area that is in focus) is very narrow. You must take care that the little sharply focused area is on something important, normally the eyes. Flowers don't have eyes, so good luck.
The greater the magnification the greater the camera shake. I found that around 1/4 sec exposure the picture had some blurring. To get sharp pictures at this magification you need longer shutter speeds, at least 1/2 sec, longer is better, which is what I did. 1.3 seconds, this allows the camera to stop vibrating and get a sharp image. Almost all SLRs act this way, with few exceptions, ( I said this to placate those who believe Their Wonder Type will not vibrate this way.)
Lastly, you must have a steady tripod. Period. I recommend this as your second piece of equipment to buy. Period. A steady camera will maximize the lens' taking ability, an unsteady mount reduces the worlds sharpest lens to at best, soft.
Hunt for that macro lens, and if the photojourney takes too long, get a set of close-up filters and mount them on your lens. I used a Nikon 135 with a +1 filter as my butterfly outfit for years. And it never let me down. Review the last blog with the cell phone and close-up lens.

Quik photonote: Name brand macro lenses are rather pricey (Nikon calls theirs Micro) and come in different focal lengths which cost more as the lenses get longer. There are some third party brands which are substantially less. Mine is an Elicar, and on the web it has a good reputation. The next route is to buy a zoom lens with a "macro" feature. This is usually 1:4, at best a close-up lens, but it will make a nice picture, my 'macro' zoom lens works fine, it just weighs a metric ton. But that weight steadies the shot. My cake, eat it too.

Cell phone camera
I've updated my cell phone and it, of course, comes with many features, games mp3 player, calculator, and alarm clock to name but a few. It also has a 1.3 mg camera. As you know, the photobear has to try out all his cameras. To be specific, my idea of a camera is that, it should operate in as many ways as possible. Being a 'you press, we do the rest' there are no controls on the camera. Dang. It is fully automated. That's not a bad thing, just a limiting thing. To our advantage, the aperture is very tiny. That equals great depth of field. (The distance, that is in focus, is about a foot in front of the camera to infinity. That's a long way.) There is an optical illusion, that if everything is in focus, the picture appears sharp. We can discuss the large aperture later. Using the small aperture, we can get, apparently sharp pictures. Also, the small aperture requires a great deal of light, such as the sun. These were taken in overcast conditions. The little camera phone performs quite well.
Above is a pine branch, to experiment with the lens' close up ability. It's pretty good. If you notice the fence in the background, it's sharp for this type of lens. The brown end of the branch is no more than 5" from the camera. That's a down right good close up. There are lots of things in the close up world to take pictures of. Like this light blue flower. I don't know what it is, a 'violet'? Inspect the picture for a moment, is something wrong?
That is the fun of photography, experimenting. Let me know what you think of this little trick. I've got more things to shoot.

because the massive depth of field starts a little further away from the camera. Hmmm...this would be a nice shot but the flower is not sharp. It's too close to the camera, about 2.5". A part of the photoworld, we can't shoot. But wait, I have accessories, among them is a magnifying lens. I held the magnifier in front of the taking lens and guessed at the distance. It's quite good, don't you think? The color shift is caused by the magnifier being coated sort of a golden hue. I do have a clear one, somewhere.

Because there is nothing to crop out when zooming at max. But,... you can crop in the computer, later.
