More Pixels Let You Get More Detail From Your Originals.

One of the first digital cameras that I owned was the Olympus C-2000Z. This was way back in the year 2000. With its 3X zoom lens it had a sensor able to record images 1600 x 1200 pixels – roughly 2.5 megapixels. I treasured this digital camera since it allowed me to bypass the all of the film, darkroom and scanning steps and go directly to the computer screen. While the consensus is that 35mm film is roughly equivalent to 20 megapixel resolution, the quality of printed images from the C-2000Z would not match those made with film but they were certainly adequate for computer display.

Of course we’ve witnessed so many amazing improvements in technology these past twenty years and many would argue that digital imaging quality has surpassed that of film.

Since then I’ve been lucky enough (or unlucky according to my wife) to own a succession of digital cameras. With each new model the sensor resolution among other features has steadily increased. For a few years I have been using the Sony A7 III camera. This is a full-frame, mirrorless device with a 24 megapixel sensor and has proven to deliver excellent images under a large variety of shooting conditions. This camera had about the equivalent image quality as my ancient 35mm film cameras about 6000 x 4000 pixels.

A few years ago I upgraded to a newer Sony A7R IV camera mostly for its advanced autofocus and high burst shooting capabilities. It also gave me another feature – a sensor that captures 9500 x 6300 pixels – an astounding 60 megapixels of imaging data.

Shortly thereafter on my next photo excursion by car, I headed out west with the A7R IV.

Below is a photograph that I took when I stopped to shoot a large cattle feed lot near Ogallala, NE. I was standing across the Interstate highway about 100 yards from the lot fence.



The size of the original image is 9504 x 6336 pixels but for this web article the original has been reduced to 600 x 400 pixels (or 1200 x 800 if you click to enlarge)
.



Below I have cut portions from the original image to show you the amount of detail this camera is capable of recording. These portions are not enlargements. They are part of the original 9500 x 6300 image that have been cropped to fit on the computer screen.



Here are the cattle that are standing next to fence adjacent to the highway. You can clearly see the detail of these animals.




Here you can see the silo with the logo towards the back of the feed lot.



Lastly is an even smaller potion of the original image that shows even more detail of the silo.



Hopefully you can see why high resolution equipment is useful when shooting subjects such as scenery or wildlife. Capturing so much detail enables you to crop portions of your original photograph to achieve a desired composition.

How Size Matters

When picturetaking, most often I’m concerned about the subject that is closest to me. I’ll pick the length of the lens that emphasizes the subject.

But there are often times that I’ll want the subject to fit in nicely with the background. By using a zoom lens, I can compose the subject in the viewfinder by varying the lens length setting.

While taking these photographs, I stood in the same place at the same distance from the foreground subject. I changed only the length of the lens (using a 24 to 240mm zoom lens).

As I’m not verbally astute enough to give you a proper explanation, I’ll show you visually how changing the lens length interacts with the perspective of the background.

My favorite is the last photo taken with the longest lens setting which emphasizes the mountains in the background.

For those that are interested, the foreground subject is the Moulton barn along Mormon Row in Grand Teton National Park. The background are some of the iconic mountains of the Teton Range.




For reference this is a photo taken with an iPhone at 4.5mm (equivalent to 26mm lens)

Using Smaller Frames

On my computer desktop, I have a folder labeled “To Be Printed”.

Every once in a while as I’m editing my photos, I’ll drop a copy of a favorite image into the folder. As the number of images within the folder grow, I feel compelled to make prints and get them up on the wall.

Years ago I realized that I didn’t have to always make huge prints. By printing smaller sizes more photos would see the light of day and keep from setting my wallet back too much.

To make best use of the limited wall space, I started to use sets of identically sized frames. They are light weight with glass or plexiglass to protect the prints and easy to hang.

A few of the favorite photographs get special treatment – they are printed in a larger size.



these are all 4″ x 6″ prints



here is a small section of the wall with three different sizes



these are all 8″ x 8″ prints



these two prints are mounted in larger 16″ x 20″ frames



this single print is 24″ x 36″



So get those images out of your “To Be Printed” folder.

When your “To Be Printed” folder gets filled again, you can simply change the photos.

Remember that you don’t have to think big; smaller sizes make attractive displays.
