  • Quirks of the Nikon COOLPIX P100

    Nikon COOLPIX P100

    This was a pretty good superzoom fifteen years ago, and it still can produce good pictures. It takes more effort to get those good pictures than with most of old Pa Pitt’s other outdated cameras, though, and sometimes he wonders whether the results are worth putting up with its eccentricities.

    First, this camera takes a proprietary battery. Almost all cameras these days do. Camera manufacturers were shamed out of using AA batteries by online rants, but all the online rants Father Pitt has read against AA batteries in cameras start from the same premise: rechargeable AA batteries do not exist. Father Pitt does not know how that incorrect assumption became accepted dogma in the photography world. With good AA batteries, the number of pictures per charge is comparable to what proprietary batteries can do, and the advantage of having one kind of battery for every camera becomes more obvious the more cameras you have. Father Pitt has a lot of cameras, so he tries to look for cameras that use AA batteries. But this camera came at a very low price, so it was worth trying out.

    A more serious difficulty is that the separate battery that runs the clock and keeps the settings is defunct, and it cannot be replaced. With most cameras, this means the minor inconvenience of having to reset the date and time with every battery change. With this camera, though, all settings are reset to defaults with every battery change. That would not be a problem if the default settings were reasonable, but they’re rubbish.

    First of all, this is the only camera Father Pitt owns that does not default to its highest-quality image setting. Fine, Normal, and Basic are the three settings available, and the camera defaults to the middle one. At the “Fine” setting, the camera can store more than six thousand pictures on a 32-gigabyte card, so there’s no good reason to skimp on quality.

    Next is the “AF area mode.” At the default “Auto” setting, the camera hunts around for things to focus on and picks a different one each time, usually the wrong one. Setting the mode to “Center” makes autofocus work reliably.

    Then comes “Distortion control.” Like most superzooms, this one trades a fair amount of lens distortion for its long zoom range. You can set the camera to correct that distortion—but the setting is off by default.

    And here we run into one of the other odd quirks of this camera, which is that you can’t have distortion correction and exposure bracketing, or a number of other things. You must choose one or the other. The manual has a two-page chart, in small print, of “functions that cannot be applied simultaneously”—and it leaves out a lot of things, which you can only find out by experiment. For example, it doesn’t tell you that you can’t use distortion control with auto bracketing.

    Next on our list of bad defaults, we go to the “Optimize image” submenu. Here we ignore the second level of options and pick “Custom,” which allows us to adjust the contrast, sharpening, and saturation, all of which are much too aggressive by default. Father Pitt sets them all to the lowest levels.

    Because the settings are lost every time the battery is changed, this routine has to be repeated every time the battery is changed. To be fair to the camera, it was not designed to lose the settings; they were meant to be kept by the clock battery. But it is also fair to point out that the clock battery was designed not to be replaceable, and online chatter indicates that it failed early in a large number of these cameras. And it is also fair to point out that other cameras do not lose settings when they lose the date and time; other manufacturers found a way to store those settings in nonvolatile memory.

    Finally, one other annoyance: the camera is not smart enough to take the zoom into account when using Auto ISO mode, and the image stabilization is unimpressive. To get a sharp picture at the long end of the zoom, it’s necessary to set a higher ISO speed by hand, and then remember to set it back after retracting the zoom.

    All right, but what about the pictures?

    Well, they’re kind of lousy at the default settings, but once the settings are tweaked, they’re very good for a superzoom. The camera will not save in raw format, but the CMOS sensor compensates for that somewhat. Father Pitt likes to use exposure bracketing, and the three exposures are taken quickly, with the camera ready for another three in a second or two. These bracketed exposures can be made into HDR pictures that preserve a high level of detail in shadows and highlights.

    So, for the shopper looking for a cheap used camera, is the P100 worth it?

    If you have a choice (and that’s what online auctions are for), old Pa Pitt would recommend something else. His Fujifilm FinePix HS10, for example, has the same resolution and came out at the same time, but it is far better at everything it does, and it has more capabilities, including saving in raw format. Also, its internal clock still works.

    But if you see one of these Nikons in a flea market for $5, well, you can get some very good pictures out of it.

    A few pictures taken with the Nikon:

    Lut’s Meat Market

    Lutz’s Meat Market, Hill District. This is one of those HDR pictures made from three bracketed exposures. The speed of bracketed exposures is one of this camera’s chief recommendations.


  • Easy to Use

    A pocket digital camera was sitting around, and Father Pitt picked it up to see whether it might be worth using. Here are the Modes:

    Scene Recognition Auto

    Auto

    Program

    Natural & Flash

    Natural Light

    Portrait

    Baby Mode

    Smile & Shoot

    Landscape

    Panorama

    Sport

    Night

    Night (Tripod)

    Fireworks

    Sunset

    Snow

    Beach

    Party

    Flower

    Text

    But you can’t control shutter speed, aperture, or focus, because that would be too hard to figure out.


  • Meet Frankencamera

    If Victor Frankenstein had a camera, it would probably be put together like this. The camera is a Sony Alpha 3000. The lens is German and more than seventy years old (probably; old Pa Pitt is not sure about its date). It’s a Wirgin Telepar 105mm lens, which makes it the full-frame equivalent of 157½mm on the Sony with its APS-C sensor.

    Father Pitt picked the Sony because its image quality was said to be excellent (and it is), but also because its E-mount, with inexpensive adapters, could accept a wide variety of ancient lenses that he happens to have sitting around. The Telepar is a 42mm screwmount lens, and the number of lenses made for that mount is staggering. Father Pitt has half a dozen of them from the days when he used a Praktiflex and a Zenit.

    Now, what is the point of using a lens like this when there are modern lenses that are better and more adaptable? Well, for one thing, every lens sees the world differently. You won’t get the same picture from this lens and from a modern lens at the equivalent focal length. You might get a better picture from this lens. You might get a worse picture. But you’ll definitely get a different picture.

    Second, attaching a manual lens to a modern camera wrests control of the camera from the electronics. The camera doesn’t know there’s a lens at all: it has to be told to fire the shutter whether it sees a lens or not. The photographer has to set the aperture on the lens itself, and he has to focus by hand and by eyeball (and with the assistance of focus peaking, which he does not disdain).

    Third, a prime lens—one that has only one focal length—makes one think about composition differently. Old Pa Pitt makes full use of zoom lenses when he has them. But that laziness comes at the price of some second-rate compositions. When the only way to change the composition is with one’s legs, one puts more thought into the composition.

    Father Pitt spent an hour in the Union Dale Cemetery with this camera and lens, and he was pleased with the results. Here are a few of them:

    Fall colors in Union Dale Cemetery
    Recording angel
    Duncan mausoleum
    Fall colors
    Monument for a child
    Fall colors
    Duncan mausoleum

    The Telepar will get more use. When it is not in use, it will continue to live in the tube in which it came to Father Pitt: a tube labeled “CLOSTRIDIUM HEMOLYTICUM BACTERIN… For Use by Qualified Veterinarians.” It fits the lens perfectly.


  • The Big Advantages of Little Sensors

    Fujifilm FinePix HS10
    A small sensor means a big lens range on Father Pitt’s Fujifilm FinePix HS10.

    Everyone knows that big sensors are better. All other things being equal (and all other things never are equal, but we’re doing our best to make a fair comparison), a larger sensor will create less noise and better pictures. It will also give the clever photographer more control over depth of field, so that the photographer can go to photography fora on the Internet and talk about bokeh with other people who appreciate a good bokeh and like to use the word bokeh in casual conversation.

    Not many photographers talk about the advantages of little sensors, though, and since old Pa Pitt has a contrarian streak, he will step into the void.

    Aside from the cost, there are three important advantages to small sensors.

    The first is the size of the lenses. Father Pitt’s Fuji superzoom has a lens whose focal length would range from 24mm to 720mm—if it were on a full-frame camera. (“Full frame” in digital cameras means having a sensor the size of a negative or slide from a 35mm film camera.) Now, a 720mm lens on a full-frame camera would be awfully heavy. It would want its own seat on the streetcar. It would not slip neatly into Father Pitt’s little plaid camera bag with room for two other cameras.

    The very top of the Cathedral of Learning
    Top of the Cathedral of Learning. It would take a whole lot of lens to stand on the ground and get this picture of the second-tallest Gothic building in the world on a full-frame sensor.

    The second big advantage is depth of field. Photographers love to talk about bokeh, because knowing the word bokeh is one of the main things that set them apart as real photographers. It just means “blur” in Japanese, but “blur” doesn’t sound technical at all. And it is certainly true that how the out-of-focus parts of an image look is an important part of the aesthetic impression it makes, and good blur can be used to emphasize the things that are sharply in focus.

    Verbascum blattaria
    Look! Bokeh! The flower (Verbascum blattaria) is in focus; the background is blurred.

    But deep focus is also valuable—having everything in focus throughout the image, even at widely disparate distances from the lens. Father Pitt will not go into the technical details of how sensor size and aperture interact to affect depth of field. The important thing for our discussion is that, whereas larger sensors allow more distinction in focus, smaller sensors have the opposite virtue: they allow more indiscriminate focus, making it easier to have everything in the image in focus at once. This can also be a desirable quality. In the history of art, as far as old Pa Pitt knows, it never occurred to a painter to blur the background to emphasize the foreground, until photographic images had made us aware of that possibility. We do not naturally perceive the world as partly focused and partly blurred. As soon as we think of an object in a scene, our eyes focus on that object. It takes an unnatural effort to focus on one object while being aware of the part of our vision that is out of focus. The popularity of the buzzword bokeh, Father Pitt thinks, has caused photographers to suppose that images are attractive only when they have proper blur. In old Pa Pitt’s opinion, blur is a special effect to be used sparingly and with intent.

    Arcade under the Bell Telephone Building
    Arcade under the Bell Telephone Building along Strawberry Way. Old Pa Pitt likes this picture, and it depends for its effect on fairly sharp focus from front to back. The Fuji camera above took this picture, and the small sensor made it easy.

    The third big advantage of small sensors is in macrophotography. It takes special lenses or extension tubes to focus very close with a full-frame sensor. Many relatively inexpensive digital cameras, though, can focus down to half an inch without breaking a sweat. Moreover, the depth-of-field advantage of a small sensor makes it possible to get a reasonable picture of a tiny object in reasonable focus. Photographers often resort to making “focus stacks” of thirty or more images to get one in-focus picture of a tiny thing, but in many cases the same effect could be yours just by using a much cheaper camera.

    Lamium maculatum
    Spotted Henbit (Lamium maculatum). In this very close picture of a tiny flower, there is enough depth of field to keep the details of the whole flower and the adjacent leaves in acceptably sharp focus—which would be more difficult to achieve with a larger sensor. Photographed with the Konica Minolta DiMAGE Z6.

    So is old Pa Pitt recommending that you dump your expensive SLR and pick up a cheap superzoom instead? No, but he is recommending that you pick up a superzoom in addition. A big sensor gives you a huge advantage in image quality, as well as the ability to play with bokeh until you’re absolutely sick of hearing the word bokeh. But there are many times when a small sensor is a big advantage. Having the right camera for those occasions will make it much easier to get the picture you want.


  • Why We Still Use the Cranky Old Kodak EasyShare Z981

    Kodak EasyShare Z981

    The Kodak EasyShare Z981 was made toward the end of Kodak’s production of digital cameras (the Kodak cameras you can buy today are made by a different company that licenses the trademark), and it is one of the worst and one of the best superzooms Father Pitt has ever used. It’s poorly made, slow, and buggy, but old Pa Pitt keeps picking it up anyway.

    Kodak tried to appeal to the enthusiast market with its high-end Z series, but compromises made this camera less appealing to photographers, while complexity made it less appealing to casual picture-takers.

    The construction is appallingly cheap, and bits of plastic are likely to break—the battery-door hinge is broken on this one, for example, though to be fair battery doors are the most common physical point of failure in cameras that take AA batteries. A rubber band keeps the camera working.

    If you save raw files, the camera is so slow that one reviewer suggested you put the kettle on between shots. (But, on the other hand, it does save raw files, so it earns points for that.)

    At speeds of ISO 400 or above, the noise in raw files is pretty bad, and the in-camera JPEGs are smeary with noise reduction.

    As with every Kodak Z-series camera Father Pitt has used, autofocus is fiddly, and in some modes simply doesn’t work at the long end of the zoom.

    But at ISO 64, this camera produces gorgeous pictures. The Schneider lens deserves a much better camera behind it. There is very little distortion for such a long lens, although the wide-end barrel distortion is noticeable because the camera does no correction—it has to be corrected in software later. The camera itself allows a high degree of manual control over most things, and the electronic viewfinder is good enough to make manual focusing possible.

    The pictures are the main reason old Pa Pitt keeps picking up this camera again. Under the right conditions, the pictures are clear and sharp. Father Pitt always saves the pictures in raw format, in spite of the wait between shots. Even at the base ISO of 64 they can use a little noise reduction, but they respond well to it.

    The camera has plenty of quirks. Autofocus is, as we said, fiddly. Set on “Multi-Zone,” it often fails to focus at all at the far end of the zoom range. We have much better luck with it set to “Center-Zone.”

    The auto ISO selection is not smart enough to account for the zoom lens, and the image stabilization is not impressive. Even in bright light, it’s a good idea to set the ISO to 200 or 400 for long-telephoto pictures. At 400 ISO, the noise will look dire in raw pictures, but it can be tamed in editing later. Father Pitt leaves the camera set to ISO 64 for most pictures and raises the ISO as needed.

    The controls are not bad. A wheel on top of the camera changes the most frequently used settings. Menus are simple and fairly comprehensive. Dedicated buttons for flash mode, macro mode, and self-timer are on the top. The big useless “Share” button on the back can be ignored, since all the Kodak software it interacted with is long extinct. A switch on top activates the second shutter button, supposedly for portrait-format pictures; this is a useless extravagance on a camera otherwise made as cheaply as possible, and for some reason the switch deactivates the main shutter button, so you can use only one or the other. Fortunately the software is clever enough to tell you what’s wrong if you try to use the shutter button when it’s deactivated, but it could have been even cleverer and just realized that you probably want to take a picture.

    The macro capability should be singled out for praise. The camera will focus at one centimeter, which is not uncommon in superzoom cameras but still very good. This camera, however, focuses at one centimeter with the zoom lens at the full-frame equivalent of 60 millimeters; most other superzooms that focus at one centimeter will do it only at the widest zoom setting. In effect, the Kodak focuses more than twice as close as most of the rest.

    The worst thing about the camera is the build quality. It feels cheap, because it is cheap. In addition to the broken battery door, the little plastic loop that attaches the lens cap to its leash is broken. That is probably an improvement, since dangling lens caps are always in the way.

    Old Pa Pitt will probably keep using this camera until it dies. It has produced enough good pictures that he feels as though he knows how to get what he wants out of it. But after it dies, he probably will not replace it. There is one big advantage to a camera one feels that way about: it can go anywhere, and one never worries about dropping it or losing it. For that reason alone, this camera gets a lot of use.
