And yet - how cool to have a PDA and a digital camera in one form factor ... great, no doubt. But this is not the same thing that the digital camera and a PDA separately. What good is a digital camera? Its utility. Taking from coffer cell, we take it in hand, is applied to the peephole viewfinder, shutter button feels ... We take to the hands of the camera and nothing else. To what "kiss" in the case of the Sony PEG-NR70V? Where to look? And where the shutter button to quickly "stop a moment? And that the press in order to select the desired resolution, adjust the exposure settings and enable flash? And where is the built-in flash on your camera? No flash ... On the other hand, even the most compact digital cameras (as described earlier "Soap" entry level does not count - yet it is not real camera) does not fit in your pocket. And the ones that fit, for the operational work will not do. Camera size of a credit card "looks great, but try to capture its hundred or so shots in two hours. Hands fall off ... So, a good digital camera - the device is clearly not a pocket. He needs a wardrobe trunk, or at least cover (you know, dear thing, plus optics, plus buttons that are easy to press by accident). This is not something that is "always with you." In any case, it requires attention and caution. A handheld computer - there he is in his pocket. The shape and design of the case and buttons - all of it is fit for work on the go, for extreme conditions, when even the strong and reliable notebook could easily become a costly, plastic "wood." Pocket PC is sturdy and reliable. Its easy to get out of his pocket and insert. If he had built a camera, and shoot them, you can easily ... There's your contradiction - seems to be better than a digital camera and then digital camera is worse. Let's look at an unhurried manner. What and for what applications do better. And as with these amazing hybrids controlled. It is impossible to lay those little things without cause. For the same money they paid. And even some money ...
With a camera in your phone
Let us turn to what we do not have - to mobile phones with integrated cameras. In South-East Asia, where this technique and produced similar devices are already popular enough (or at least known). In America - only just emerging. Concept phone with built-in photo module (in fact, a real smart - because of its extreme kompyuterizirovannosti) looks very attractive. Universal communication device, an electronic organizer, largely acting as a handheld computer, and yes even in combination digital camera. And all in a compact phone package that easily fits in your pocket, and in a holster on his belt, and in the business portfolio, and a purse ... Is it because such a demand communicator (just try to buy the same Treo - need a good search) that they adequately meet the specifications of the universal device for all occasions? A cell phone is universal - it is easier as a means of communication and compact as a PDA. And just more convenient to administer.

Looking through the posts of updates to foreign high-tech companies involved in the development of smartphones, I have defined for themselves are some common features phones with integrated cameras. On the phone, and kind, computer functions, these devices still do not talk - only about the photographic component. Thus, the modern smartphone with a built-in digital camera - it is a phone with a color graphic display that can display thumbnail preview images, and possibly pictures in full size format, but to show parts (moving image on the display - for a detailed view of fragments of images). However, the latter only an assumption, since the smartphone screen size of a large postage stamp can hardly be regarded as a tool for comfortable viewing images."Thumbnails" on this screen will look like painted rice grain ... Nevertheless, regular screen Smartphone allows you to use it as a viewfinder, built-in camera, and displays a menu of settings and controls.

Since the built-in camera is not really the main and auxiliary functions, it has individual buttons - control is carried out with the standard telephone keypad. That is key phone functionality is clearly overwhelmed. Purpose of the buttons have to learn, or to combine not cope. Next - a light sensitive sensor. Its physical size is small, and on the device is a type of sensor CMOS. That is, the sensitivity, dynamic range and excellent noise characteristics of the sensor will not name. Small and the resolution - the same level cameras for prints on paper are not suitable. The most that they can be used, obtaining pictures for viewing on a computer screen used as illustrations for the web-pages, e-mail messages and various directories (for example, to accompany the portraits of the respondents their address book). Separated from smatfona integrated digital camera looks pale. And together - is acceptable. Even a simplified optics, low light sensitivity sensor, the lack of exposure automation and flashbulbs are not significant drawback, since the photos are quite small, therefore, not "heavy" for sending them through a wireless connection (all new multimedia smartphone supports protocol packet data GPRS and service of short multimedia messages MMS). In other words - the photo module equipped with a smart phone is not designed to obtain high-quality photos, but remarkably suited for the rapid exchange of shots, carrying the load for informational purposes only. In practice, work with this smartphone might look like. Go, say to the store. Notice a product that I would like to buy (for example, a real digital camera, but not this built trinkets). It costs considerable money, so you need good 'wife'. " We photograph your favorite thing and send a snapshot of his wife. Immediately get an answer - "dreaming" ... Everything is clear, not destiny ... or other situations. Walk yourself to Autumn Park, notice the charming young lady. We photograph it, send a picture to someone. He instantly falls in love, does offer the young lady, will marry ... And so in a spirit of love Mexican TV series .... Say - self-indulgence? Course, pampering. Arrant self-indulgence. But without this indulgence life seems fresh.
Camera in a PDA
Choice, in general, is low. On the one hand - not once referred to me and already out of production Sony PEG-NR70V and coming to replace him PEG-NX70V (ie adapted to multimedia applications clone Palm `a), on the other - a classic Pocket PC 2002 and its latest modification, retrofit the merged photo module. This all the different and limited (except for rare "vagrants" exotics, such as PV modules for the Palm `s normal that we do not consider). Since Sony does not compare computers with what we dwell on a particular model - for NR70V (more advanced NX70V in Russia is not yet available). On the computer, again, do not tell (machine just class!), Only the built-in camera. And it has roughly the same features as the camera cellular smartphones. Sensor is a tiny physical size (by the way, this setting determines the quality of the camera - the sensor is more, the camera is better) and low resolution. What is a photograph of a resolution of 320x240 pixels? Nonsense, not a snapshot ... The newest model NX70V resolution is doubled (640x480 - standard VGA), but the image quality is reflected only slightly, because in the new and old models applied to the photosensitive sensor CMOS.

Furthermore - optics. By Sony would be expected of optics Carl Zeiss, which supplies it with full-featured digital cameras (among other things, some of the best in the amateur class). But it did not happen. Optics is, but some ... miserable. Automatic Exposure and Shutter - at pyatidesyatidollarovyh "shoot cameras." Flash, of course, no. Can I rent such a camera? Why not? Especially if the pictures are for viewing on the Pocket PC ... And for the serious amateur photography training, part of which is the fine art photography (and, to a greater extent than it might seem - every camera owner sooner or later tries his hand at the art of photography), it is unlikely Do. Is it too expensive like fotoeksperimenty? Should I put off for vague murky picture six and a half hundred dollars? .. I think we should. It also is not just a camera and a computer. And the built-in camera it - is not only a camera but a video camera and a small three-dimensional scanner. In any case, better to have a pocket-sized machine with such a makeweight than without it ... Around the same consideration and be guided by the owners of Pocket Pc, enticed by the acquisition of the merged photo module format Compact Flash. At approximately the same cash outlay, they get more than the owners of machines from Sony. All the same computer class Pocket PC to practice amateur photography fit better than the Palm. A photo module CF (eg, from Pretec) on the procedure of implementation of the integrated camera Sony. To learn more about what can shown in the photo compact device is possible from our review.

| Digital camera on the expansion card Compact Flash |
True, working with attachable modules is not such a simple thing. Firstly, the PDA must be a slot format of CF. Secondly, the camera has a CF slot and can not increase memory machines. And the pictures just need additional memory. Wow them stored somewhere? Released two - to change the outdated computer to a new model in which either there are two slots for flash memory cards at once (CF and SD), or compact SD card slot built into the computer, and CF slot is designed as a removable "jacket". Or the maximum free memory on PDA unneeded applications and to stock up on a removable memory card. In this case, work with your camera will be smack in the circus juggling - insert photo module and the memory is filled with images of the CCP, then dismantle the photo module and replace it with a memory card on which overwrites the photos. Repeat this tedious trick as long as the card runs out of flash memory or battery will not sit down the computer ... By the way - Join photo module is very voracious. They are able to put the battery svezhezaryazhenny Pocket PC for some one and a half to two hours ... What we have in the "bottom line"? What are the lessons? If you have a choice, it is best to stay on a tandem from the PC and Pocket PC photo module CF. In this case, the user will receive another benefit - the ability to use established skills. The fact that some attachable modules next to the lens mounted telescopic viewfinder - the same prism, in which photographers drop is not the first century.
As this shoot
Whatever we were rich, modest digital "soap box", a smartphone with built-in camera or in the same "photo-computer, the basic techniques of photography remain the same. They are due to design own cameras. First - composite solutions. To frame was more or less successful, remember the shortcomings of your camera optics. The simplest odnolinzovy lens - it's monocle (which may be options, but the general features of behavior "mylnichnoy" optics are similar).His features are soft picture (do not expect an abundance of small details in the picture, although the details of a cheap CMOS-sensor does not transmit at all desire), the uneven illumination of human box (in the center of the illumination is greater on the edges is less), defocusing at the edges of the frame. From this rule - the plot significant objects shooting always be placed in the center of the frame. Objects located on the edges, get blurred and darkened. That is, for large group portraits such as cameras are not suitable. Next - Focusing. Hyperfocal distance of the lenses installed cost "shoot cameras and built-in camera, should provide a sharp image at a distance of 40-50 inches to infinity. But this is only a theory that the practice is not confirmed. Due to the fact that the sensitivity of the sensor "walking", and the lenses are made of plastic and are prone to thermal deformation (and a number of technical reasons, chief among them - simplified requirements for quality optics), depth of field is limited to a fairly narrow limits. More or less harsh on the images obtained objects located at a distance of 2 to 5 meters from the lens. This distance should be the main compositional guideline. Because of the limited range is guaranteed to correct the focusing holder built-in camera, in many cases will have to forget about the landscape and macro photography. In many - but not all! Budget camera and a powerful graphics editor can do real miracles. With the help of Photoshop flaw image can be turned into advantages. Apply to, say, effective filters and turn zamylenny and clearly failed in this landscape art miniatures ... color noise. In the picture they look like patches of color in the shadows and as halos on the borders of the brightly lit and shaded areas snapshot. To avoid this phenomenon, try to have the subject in the area of uniform illumination that is not in direct sunlight. If, however, have to shoot in bright sun, illuminate the face of the person you are photographing, a screen of white paper - like a mirror. Or move closer to the bright wall of a building. Usually this is enough. Backlighting and night shooting, "soapbox" is too tough. Although, again, pmozhno experiment. By the color distortion and an increase in noise level leads shooting in artificial light. The fact that the CMOS sensor is initially calibrated to the white sunlight. Correction function of the light balance, which is necessarily present in the vast majority of digital cameras middle and high price category, the entry-level cameras available. This means that the bulb will inevitably give yellow and fluorescent - a bluish tint. The position would save the flash, but it's not embedded cameras. A flash cost "shoot cameras" only lead to a "vypalivaniya - excessive illumination of a subject (remember, talk about cheap cameras, for which many of the flaws are forgivable). Support tools. Here again I draw attention to the editor, Photoshop. User to "Soap" it is necessary as anyone else. A set of filters to help get the most seemingly bad shots and in some cases to compensate for the technical imperfection of the camera. Of the tested me I can recommend two great filter. This ASF Digital SHO, which aligns the level of brightness of different parts of the picture, pulling the dark underexposed photos. And the filter Band Aide, allowing to reduce color noise ... However, Photoshop filters for processing of amateur photographs is very, very much. The choice is enormous ... more puzzling. The cost of graphic editor Photoshop with just two additional filters exceeds the cost of digital "Soap" in more than ten times. These funds could buy a second PDA with built-in camera. Or high-grade camera and a PDA separately. The authors, translation:
