Seasonal fun


I love autumn in New England. The mixed hardwood forests can produce a magical display of color. So, I have to post some nice seasonal image.

However, while I am sharing here an image from New England, this particular image is not peculiar to the region. This image is simple seasonal fun that happens all across the country. This was a simple grab shot; driving down a rural road, I saw this beside the road, stopped the car, took a handful of photographs, and then left.

The artistic vision here is not my own, but someone else's. I can only claim good composition and exposure. The one trick here regards the white fence, which was overly bright relative to the rest of the scene; so I underexposed the image by 2/3 stop and later adjusted the curves in Photoshop.

An Evening with Photographer Joe Buissink

Just returned from seeing a presentation by photographer Joe Buissink. I confess Joe shattered any pre-concieved notions I held about high-paid celebrity photographers. He shared many images and his passion for capturing fleeting moments between people.

He still shoots film and his clientel are people who seek that and appreciate that. He primarily shoots available light at ISO 1600 and 3200. His images tend to be less grainy than most of us associate with high ISO. His film processing lab will visually inspect the film during development, empirically pushing the development until the density is good. This avoids low density low contrast, which requires compensation during printing and thereby incurs enhanced graininess.

Joe seeks emotional moments, not necessarily perfect sharpness or perfect composition. His pitch to prospective clients is more about himself and his passion. He tells the stories behind the images that you would not know from the image alone. Once people are hooked on his passionate approach, they tend to give him less direction and restrictions. He typically does not have to align himself to a required shot list.

Joe does more than just weddings. He recently completed work on a book about autism and the images comminicate a compelling joyful story. He photographed Stephen Spielberg's birthday party, Christina Aguilara on tour, and the closing episode of the Frasier television show at request of Kelsey Grammer.

The Buissink approach to photographing people is eye opening (to me anyway) and it was a truly enjoyable evening. However, it is no secret that he caters to very wealthy people and the cost for his services is adjusted to their financial means. I personally do not know anyone who can afford him.

Pixels (part 1)

Perhaps the most common question regarding digital photography is ... how many megapixels do I need? The answer depends upon how you intend to use the photo. You need to answer two questions: how large will the photo appear (inches or centimeters) and how many dots per inch (or centimeter).

If you want to share it on a computer screen, one megapixel is more than enough. Why? Computer displays typically have either 72 pixels per inch or 96 dots per inch. So, for example, to display a photo at a size of 6 by 9 inches, you need (6 x 96) x (9 x 96) = 497,664 pixels = 0.497 megapixels.

Computer screen: 72 - 96 dots (pixels) per inch
Photo print: 240 - 300 dots per inch
Magazine: 100 - 200 dots per inch
Poster or banner: 100 - 150 dots per inch
Billboard: 10 - 20 dots per inch

Magazines print fewer dots per inch. If you look real close, you may see the individual dots, but maybe not. It depends upon the exact printing equipment and the tendency of ink dots to blend together. Billboards, viewed from far way, use very low resolution simply because it is not apparent from far away.

So, here is another example. For a photo print 6 x 9 inches, you need (6 x 240) x (9 x 240) = 3,110,400 pixels = 3 megapixels. More pixels in your camera means that you can get larger prints without sacrificing quality. Using the same math, you can easily see that a 20 x 24 inch print needs 27 megapixels.

You may ask: 240 dots per inch? My printer supports 1000 dots per inch.
OK, here is the bottom line. If you print at the higher resolution, can you see a difference in the final print? You might see a tiny difference, but 240 dpi usually provides excellent quality and sharpness. If you are using a photo lab to make your prints, consult their guidelines, but 240dpi or 250 dpi is very common.

Water Lilly

Paddling the river this evening, I had planned on a quick trip; however, I stopped a half dozen times to photograph flowers (aquatic or nearly so). The day was waning and yet another stop may mean I would finish my trip in the dark. But each time I stowed the compact camera safely in my dry bag, I soon found another reason to dig it out of the bag yet again. This continued until the battery expired.

Worth a thousand words?

While I have long loved nature photography, sometimes a still image, a photo, cannot possibly communicate a simple concept that a video can. Here is an example of moving fog with some unexpected colors. Although I tried to photograph this as a still image, it just looked like mush. Had to switch to video.
