Goodbye Kodachrome

It has been many years since my last roll of Kodachrome. Like most of the rest of the world, I “went digital” a long time ago. So the time for Kodachrome has passed and it is departing into its rightful place in history. 

I started using Kodachrome as a college student more than half a century ago. Kodachrome was not just a color film, one of many tools for my photography passion, to me, and many others, Kodachrome was a potent teacher.

With Kodachrome the exposure had to be spot on. The slightest bit of over-exposure and the highlights became a chalky mess, a bit of under-exposure and the shadows became inky black. You learned to us your exposure meter. Reading the grey card, the bright areas, the dark parts – it was a bit of a production to take pictures with Kodachrome. You could not see the results for a couple of weeks while the film was at the lab. If you did not get it right, that exercise was a learning experience and history.

Since Kodachrome yielded slides, mounted slides, there was nothing you could to about the framing after the shutter was released. So you learned to see the final picture, all of it. Viewfinders had sophisticated parallax correction to help the photographer get it right. You physically moved in and out or - more rarely - changed to another lens. Zoom lenses were still a distant dream.

When I first started using Kodachrome, the daylight film had a speed – sensitivity rating – of ASA 12 (that measure, “American Standards Association” has now give way to ISO numbers of equivalent value). That slow speed required very careful management of the camera settings. If you wanted any measure of depth of field and wanted to use the aperture at f/11 that meant 1/30 second for daylight scenes. Long shutter speeds demand very careful shooting. Kodachrome taught to spread your feet, to press the elbows into your sides, and how to breathe.  For action photos like sports, to use short exposure times, like 1/500 second, meant shooting with the aperture wide open. This yields a shallow depth of field and demands perfect focus.

Yes, to use Kodachrome successfully meant knowing your camera, your subject, and applying that knowledge with care.

There was for me another very important lesson. Kodachrome was expensive, more expensive that other color films. As a poor college student I had to be very frugal. That meant making every exposure count.  It also meant that you had to press the release at just the right moment. Cartier-Bresson made Cardinal de Retz’ “decisive moment” his trademark and book title.

 

Today there is nothing to teach these lessons to aspiring photographers. Technology in modern cameras takes care of all these matters. Exposure is evaluated by hundreds of sensors and the computer determines the appropriate settings. If it still is not completely right post-processing can make the corrections.

Today zoom lenses are ubiquitous. Getting the framing right is just a twist of a control. Cropping in post-processing is standard operating procedure.

Holding the camera steady has long ago been made obsolete by image stabilization.

The primary controls on modern cameras are not shutter speed and aperture – no, you select “scene mode”, like: Portrait, Landscape, Close-up, Sports, Night Portrait, Night Landscape, Party / Indoor, Beach / Snow, Child, Sunset Dusk / Dawn, Pet Portrait, Candlelight, Blossom, Autumn Colors, Food, Silhouette, High Key, Low Key (these from the just introduced Nikon D7000). The computer inside then judges the correct settings. No worry about depth of field or a blurred subject because it moved too fast.

“The decisive moment” – history – today some cameras capture images even before the shutter is pressed. Just select the best one.

Us old-timers can only shake our heads and wonder about todays youth. How will they ever learn? We had it easy: When you mastered Kodachrome, you mastered photography.

So a fond goodbye to Kodachrome, that stern taskmaster, and brilliant teacher.

 

P.S. The illustrations here are faked: The photos were flipped in post-processing for esthetic reasons, modern technology rolls on. Click on any one to take you to a slide show of old Kodachrome photos of mine – nothing special – all from my learning days.

Sunscreen for my Camera

On a bright, sunny day the sun can heat up dark objects in no time at all. My camera is black, carried on a neck strap, it becomes uncomfortably hot to the touch.  That kind of temperature cannot be good for the insides of the camera either. My solution is to dress the camera in white. Take a look at the picture.

A child’s t-shirt is just the perfect way to protect the camera from the unrelenting sun. My quick-connect neck strap goes through the sleeves. The t-shirt can stay in place to take a picture, with the bottom of the shirt pushed up over the lens, the viewfinder is accessible through the top of the shirt.

For better control of the camera, the t-shirt can be easily slipped up on the straps, it then stays out of the way amazingly well.

I have not drawn any unusual attention from any passersby, but I did have quite an experience acquiring the t-shirt. As an older person walking into a baby goods store immediately got me marked by the sales clerks as someone shopping for a grand child. Grand parents have a reputation of sparing no expense when it comes to buying a present for a grand child. So I was shown all kinds of fancy little shirts in all colors of the rainbow – except, of course, white. There was gorgeous lace trim, beautiful embroidery, thematic designs from baseballs to spacecraft. No plain white. When the clerk finally asked “are shopping for a boy or a girl?” my reply “neither, I want a t-shirt for my camera” really got me strange looks. I wasn’t sure whether they were trying to decide between calling security or for an ambulance. Trust me, delegate the shopping of a baby-size t-shirt to a young mother!

My camera stays cool, even if this is not the coolest in fashion statements. Should you see me with my well-dressed camera in a park or town, just give me a wave!

Musings on Zoom

It is nigh on impossible to buy a camera that does not have a zoom lens. Inexpensive cameras that do not sport the expensive optics still have, and advertise, “digital zoom”. Why is zoom so popular? My feeling is that it has to do with human vision. We see the world with a very wide field of view, nearly 180 degrees wide, yet the primary area of interest can be very small. Indeed when watching television the TV screen takes up typically less that one percent, less than one hundredth, of our field of vision.

Photos do not really reproduce the scene as we saw it and might remember it. We cannot visually zoom into the picture the way we could the actual scene. We have learned that maybe it takes several pictures, a wider view and a closer look. Even then we can be let astray. Here is a pleasant picture.

I saw a butterfly and took the picture. Right away I realized the picture I got was not what attracted my attention. This is really what I thought I saw:

Now this is just a crop of the first picture. Had I performed the operation in the camera it would be called “digital zoom”. It works here because of the limited resolution of pictures on computer monitors. There are cameras sold with 8 megapixel sensors and “8x digital zoom”. Pity the poor buyer who falls for that – pictures with the resolution of a large postage stamp at maximum zoom. But I digress.

So the zoom lens gives us the ability to capture the detail that we so easily discern in real life. But it takes several pictures.

There is a technology that lets us see pictures with a wide view and yet discern small detail. Not quite as easy as just glancing at a spot – you need to use the mouse, but still quite amazing. I am talking about Microsoft Zoom.It.

Here is a picture with a wide field of view – almost as wide as the human eye sees – over 100 degrees horizontally – and you can zoom in to see detail anywhere in the scene. This picture has over 25 megapixels.

For best viewing, maximize your browser and click on the to see the image full screen. Use you mouse wheel to zoom and drag picture as desired.

Dud to Showpiece–Artistic Effects as the Hero

We all have some photos that should have been discarded in the camera but somehow seem to have some merit – maybe form, or color, or patterns – that appeal in spite of major flaws. Let me show you what I am talking about.

Here is a pleasant photo of a jelly fish. Unfortunately, the jelly moved and I moved the camera. The small close-up shows the flaws. This just is not “gallery” quality. I liked the photo, however. Maybe it could be used as a graphic in a brochure or greeting card …

Word 2010 to the rescue!

Word 2010 has a variety of artistic effects that can hide the flaws and still result in a pleasing illustration. “Artistic Effects” shows tiny thumbnails of the actual picture with the effects applied. When the pointer is moved to the effect it is applied to the actual picture so it can be previewed. For this photo “Mosaic Bubbles” seemed like the most appropriate effect. I selected “Artistic Effects Options” and adjusted the Mosaic Bubbles setting to a “Pressure” of 100. This reduced the space between bubbles and made for a cleaner look. So here is the final result, but there is more to getting there.

Click the picture for a large view.

Word 2010, as well as the other application in Office 2010, has some peculiar and unexpected ways of handling pictures and artistic effects. It allows only one effect – if you choose another, it restores the original picture that was inserted and applies the effect to it. Also, it changes the size of the image when saving the file. So do your work in one session and don’t save. How do you get the picture with the effect applied? Right-click on the picture and select “Save as Picture”. You can specify the file type – for most uses you will want JPG as the format. All metadata will have been stripped from the picture.

If it seems desirable to apply more than one effect, then the procedure is this:

• Insert the picture
• Apply the first effect
• Save the modified picture – right-click – Save as…
• Insert the modified picture back into Word
• Apply the next effect.
• Repeat as desired.

Let me demonstrate this with another photo. This picture has a rather dark background, the fish does not stand out very well – the edges, the tail – disappear into the background. So first I lightened the photo a bit in Windows Live Photo Gallery. Then inserted it into a blank Word 2010 document.

Background Remover

Word has a marvelous background remover tool. Here is the first default view using the tool. I set the cropping so all of the fish is included. Then I used the “Mark Area to Keep” and the “Mark Area to Remove” tools to draw lines into the tail to keep and small areas between tail and fins to remove. This is really quick, fewer then ten short strokes, you can see the “+” and “-” marks in the second illustration. Clicking “Keep Changes” removes the background.

I saved the picture as described already. In Paint I set a large area and colored it teal and then did a “Paste from” and inserted the fish picture. Back to Word for more artistic effects. First I applied “Plastic Wrap” to give the picture a ceramic tile look. Another save and re-insert to Word. This time for an overall texture effect.

Effects in Word 2010 scale differently with different picture sizes. I could not get a course enough texture for the original size. After resizing the picture the texture (at maximum setting) was to my liking. Here a couple of progress illustrations and the final result.

Click on the larger image for a full size view. I am happy with this fish. It is much more impressive than the original photo, don’t you think?

Maybe even good enough to hang in the café!

Art Effects from Photos - using Excel 2010

A photo outing usually results in a large number of images with just a few that are worth sharing. My trip to the Georgia Aquarium was no exception. But there is one picture in particular that I seem to enjoy looking at again and again. The pose, patterns, colors, shapes, just seem to work for me. It appears to just cry out for presentation in different transformations.

So here, with apologies and all due respect to the ichthyologists out there ---

“My Variations on a Theme by Volitans Lionfish”

Most picture organizing programs, like Windows Live Photo Gallery or Picasa, provide tools for editing and improving photos. For more extensive manipulations full-featured image editors, like Adobe PhotoShop or Corel PaintShop Photo, offer a huge palette of tools. A surprising and unexpected source of artistic effect tools is Microsoft Office 2010.

Excel is not just for numbers anymore!

Not until after you insert a picture into a cell and click on it does Excel 2010 provide a “Picture Tools” tab (this is also true of Word 2010 and PowerPoint 2010). One of the commands in the Adjust section on the Ribbon is “Artistic Effects”.

It is an absolut pleasure to use. The menu shows little miniatures of the selected image with the various effects applied. Hover the mouse pointer on one of the miniatures and instantly the effect is applied to the picture so you can preview it. There are also options to adjust the effects such as brush size.

Other options allow you to soften or sharpen the image or to change brightness and contrast – with the Corrections tool – or to change the coloring with the Color command.

The Color menu allows control of color saturation and “color tone” – color temperature. It also has a palette of intriguing “recolor” options. These recolor options include some interesting black-and-white choices as well as effects for changing the overall picture coloring. You can see the miniatures here for my favorite fish. This tool also provides a control to select  additional theme colors.

I never imagined having this much fun using Excel. This is more like playing a game – far, far, from number crunching and spreadsheets.

Why, I think I will have another cup of coffee and play on…. 

Be sure to visit the Gallery page!

Enhancing aquarium photos

Pictures taken in aquariums can turn out less than stunning. Especially for creatures in large tanks, the photos may lack the crispness that brings an image to life. Let me show you what I am talking about.

Here is an otherwise nice photo of a grouper. It looks hazy and, well, bland, because of the turbidity of the water.

The photo has nothing that is black, and nothing that is white. The range of brightness values can be best illustrated by looking at a histogram of the photo. A histogram plots the distribution of tones from black to white along the horizontal axis, with the number of occurrences for each value on the vertical axis. Most image editing programs provide such plots, many cameras even do so. Here is the histogram for this image as shown in Windows Live Photo Gallery. I like that tool because it is simple to use and provides a number of very useful tools for enhancing pictures.

As you can see there are no pixels near the black (left) end of the scale and none on the right end. Photos with pixels covering the entire range from black to white are visually more satisfying, they “sparkle”.

One of the first, and easiest things we can do is to stretch out the pixel tone values. Live Photo Gallery makes that quite easy. Note the little markers on each end of the histogram. These are actually slider controls that can be used to set the black (left) and white ends of the spread of values. Not only can this adjustment be made by just dragging with the mouse, the results of the operation are displayed instantly and continuously. Here is the view of the program with the range adjusted as it appears best to me.

Notice that I dragged the black end slider (see red arrows) up so it is just at the left end of the pixel values. I did not bring the right, white, control all the way to the highest pixel. It just looked better to me this way. Also note that I set the Color temperature to the the warm end of the range. Live Photo Gallery provides, as do other similar programs, additional controls. These too operate “live” so you can see the results as you move the sliders. Now, doesn’t this improve the photo nicely?

There is one other disturbing little flaw. Note the white “running light” on the fish. This must be a reflection in the glass, so I want to get rid of it.

Image editors, especially the pricey, full-featured ones, offer great tools for retouching and modifying pictures. Live Photo Gallery (here in the 2011 beta edition) has a very easy to use retouch tool.

Click on Retouch, drag a rectangle around the flaw, and Photo Gallery analyses the area around the flaw, finds an area that would be a good match and copies it in.  It gets it right on the first try most of the time. If it is not right, repeating the operation causes it to find a better fitting patch. Really easy.

So what were the steps I took to enhance this picture?

• I “stretched” the pixels using the histogram tool,
• took the edge of the excessively “cold”, blue, cast with the Color temperature control,
• and retouched a reflection flaw.

The editing tools in your picture management of image editing program allow you to enhance your photos so they look like you remember seeing the scene, even if in actuality it was not as impressive.
