Available at AmazonI have an Alpha 300 and a 58AM speedlight that I've been using for over a year. I needed a second speedlight but didn't want to spend the 0-0 that another 58AM costs. So I purchased the 42AM. It's a very capable speedlight, especially for off-camera work.
I always shoot using off-camera flash (for my studio work). And I always shoot with ttl (through the lense metering). My biggest issue when I bought the 42AM was whether it would recognize the existence of the 58AM and the two speedlights would ttl meter appropriately. (Remember you cannot set flash ratios or groups on an a300. You need at least an a700 for that.)The answer is that they do! In other words, I can put my two Sony flash units anywhere around a subject and the ttl metering gets it perfect and adjusts the flash for BOTH units accordingly. And I can do that with just an a300! (an a200 can also do that.)
ttl flash metering is essential to dslr photography. You don't have to mess around with manual flash adjustments and do photography by trial and error. ttl flash metering will give you near perfect exposures with very little effort. And it doesn't matter if you're bouncing the flash into an umbrella, soft box, the ceiling or firing directly at you subject. The ttl system knows what you're doing and takes the "big picture" into account when determining the flash exposure. The 42AM is a very sophisticated flash that can ttl and has high speed sync for quick shutter shots. (Of course you always have the choice of using manual flash mode and setting the flash yourself. So you can be as creative as you like with the 42AM.)
One word of caution. The 42AM cannot act as a "controller" (Sony speak)for other off-camera flashes. In other words, you can't attach the 42AM to your camera and fire another off-camera flash. Only the 58AM can do that.
The 42AM is a great speedlight and it's improved my photography a lot.

One of the dirty little secrets about these white-balance filters is that almost any white material held in front of the lens will work. Melita coffee filters are often used for comparison with the latest 0+ filter. It seems, from what I have read, that Melita filters don't work as well as white plastic, but that the cheap white filters like this one work as well as those costing ten and twenty times as much. I haven't tried it yet.
(For the uninitiated: In artificial light, digital cameras need to have their white balance adjusted. This is done by taking a reading with the white cap over the lens (auto-focus OFF) and locking it in.)

The new packaging is about 3 times as big as it needs to be. This makes it hard to pack. I found five 10 packs can fit into an Altoids tin making it far easier to carry and in a more durable container. The zink paper is not as good as my dye-sub printer, but the convenient size is the reason I bought it.

pinhole can invent the simplest type of camera ever, and there is time. These cameras are used for art, entertainment, science and monitoring. You probably have one or know someone who does not. But have you ever thought about the mechanism behind a pinhole camera?
The device is not typical
The pinhole is not a function of traditional cameras and you are used both in its form. Rathertypical camera bag, a pinhole camera using a light-tight box - matchboxes and cereal boxes do. And instead of conventional glass lenses are very, very small hole so big it caused by a PIN.
But do not underestimate the cardboard cameras. Indeed, the results are impressive and sophisticated works of art. The images are only available after the exposure is much better than a normal camera, it is. Blando and crispAt the same time, and the images have an almost infinite depth of field.
Simple concept
This simple device that works well on a simple principle: Optica pin. One side of the box has a small hole. The light from outside the box goes in the hole and the image formed by the camera to one side.
To help you better understand the concept, imagine a big black box. On one side of the room is a small hole and out of the room is a friendKeep a flashlight. Now, this friend of the torch shines through the pinhole, at different angles.
Imagine the wall opposite the hole. This is a small dot is created by the beam of light shone through the hole. As your friend moves the torch, there is little even move the wall.
Now imagine taking this big box and display it in your garden. On the wall opposite the hole, is inverted mirror image of the landscape. Each pointGarden and the beam emits light emitted from the point through the hole, so that the corresponding number of light on the opposite wall.
Each point in the landscape is the output (light through the hole, and reflects on the wall) at a time, so that the entire image is created on the wall.
The largest of the scene and automatically through the hole is a longer process. It also means better results. The image is of courseare tenuous, the hole is very small.
small camera
The pinhole is used in real sizes. But still, it is much smaller than the image above. And instead of a bare wall outside the door, a dark room makes the use of a type of film. The film, which is against the wall, light or image that passes through the hole.
The device creates, with a beautiful view of the fire scene, where aSet the camera. The exposure time is usually half a second to several hours, much longer exposure time of the usual conventional camera. This is because the hole can pass the light at the point but the result is worth waiting for.
Outdoor Home Security Camera Systems are the most popular type of system for home security system installations. These systems allow homeowners to view their property and record video for playback later. This way, if anything does occur around their home, the homeowner can provide video evidence of the occurrence to police, giving a chance at recovery of any stolen property and prosecution of the perpetrators. Outdoor camera systems can be as affordable as an alarm system and provide infinitely better evidence for use by police.
Outdoor Home Security cameras have become very popular with homeowners, due to the fact that good quality outdoor cameras can be found for anywhere from $50-$150 each and can provide good quality video when hooked to a Television, VCR, Standalone DVR or even PC-Based DVR recorder, to build a home security camera system that can provide video coverage of your front yard, back yard, driveway or front door. Digital Standalone DVR or PC-Based DVR Systems can even be configured to allow you to remotely view or sometimes even remotely record from your cameras while you are at work, on vacation or anywhere in the world.
These systems provide great evidence for homeowners, so that if something ever occurs around your home, you can provide police with evidence that can lead to prosecution or even return of any stolen items. While also important for overall home security, alarm systems cannot provide any evidence or even alert you when someone is around your home.
With childish vandalism on the rise in many neighborhoods around the country, good home security camera systems are the only way to combat, deter and capture video of these occurrences around your home. It is no wonder that many homeowners have already installed home security camera systems
