35mm DOF Adapter – Do You Need One?

One of the more apparent differences between film and digital video is the way the cameras handle depth of field. Film cameras have allow for a shallow depth of field (resulting in only the subject area being is in focus), while video cameras offer a larger depth of field (resulting in everything being in focus). To achieve a shallow depth of field with digital video camcorders a depth of field adapter is generally used. Before you rush out to purchase an adapter you should ask yourself if you really need one.

Before you decide if you need one, you have to understand exactly what you are purchasing. A depth of field adapter is not a quick solution. It will not provide perfect results once you install it. They are a tool like any piece of video equipment in your arsenal. This tool, like any, requires mastering. It will take time and practice to achieve the results desired from an adapter. With that said and adapter should not be an impulse by nor one you should rush to buy/build. I will say for most videographers it is a fun tool to experiment with.

Ok, so you decided you want to go for an adapter. The first thing you should do is research. They’re are many high-end commercial solution that cost $1000+, however there are also as many ‘DIY” versions on the market ($150+) and tutorials for building your own DIY adapter. I can say i have seen footage from many of the ‘DIY’ adapters and they can be very comparable, if not superior, to commercial solutions. This is why research is the key. You can search sites like Vimeo.com for HD footage from most of the adapters out there. There are also many comparison videos there as well. While researching adapters keep in mind that there are 3 types of adapters; static, spinning, and vibrating. Static is fine, but you run into trouble with keeping the internal ground glass(heart of the adapter) clean, which results in noticeable artifacts and patterns in your footage. The solution is to add movement to the ground glass…hence the vibrating and spinning adapters. Spinning adapter are larger and use a rotating disc as the ground glass, this can actually cause a ‘pumping’ focus effect if not aligned correctly. Vibrating adapters are my personal choice. They actually vibrate the ground glass, usually in a slight circular, pattern. The vibration is very slight, but enough to make any dirt on the ground glass disappear. Usually vibrating adapter allow for speed adjustment which provides you with even more control.

Okay so you decided you want an adapter and you understand the basics of each type, now what? Now you decide if you want to attempt to build on yourself or purchase one. Purchasing a DIY vibrating adapter will run you at least $250 (most likely more), while a commercial version will be at least 3x as much. Building your own sounds like a cheap route to go right? Well, not exactly. Unless you have the parts available to you at a local store (most likely not) you will probably end up sourcing them online. And you can find great prices online, however, since there really isn’t a one-stop shop for parts, you have to factor in shipping. Which really ranges greatly from store to store. This will make a vibrating DIY adapter about $100 – 200 easy. However there are a few creative solutions utilizing PVC pipe and other easy to get parts from local stores. Tutorials for these can be found at here.

I hope this helps, also don’t forget to figure in lens support and a tripod into your budget…once you start experimenting with the actual adapter you will understand why these might be needed.

Setting Up Wireless Adapters and Network Interface Cards

For your client computers to connect to your WLAN, each of them must have a wireless adapter or wireless NIC. These adapters are small transceivers (radio transmitter/receivers) that allow your PC to send and receive radio signals. There are three main types of Wi-Fi adapters available for your WLAN: USB wireless adapters, wireless NICs, and PCMCIA cards.

A USB wireless adapter connects to your computer through its USB port. It is simple to install and enables you to adjust the location of the adapter to improve signal reception. You install a wireless NIC in a PCI slot within the computer, just like an Ethernet card; a wireless NIC installed within a computer saves desktop space. For a laptop computer, the best choice is a PCMCIA card adapter that fits in the laptop’s PC card slot

Caution: Always turn off me Power to your computer when installing internal network adapters. You usually won’t need to turn off the computer to insert PCMCIA cards or USB devices, but you may have to reboot to finish the installation.

Any time you open the case of a computer you need to take special care. Always turn off the power and unplug the cord. Don’t force adapters into PCI slots, and be careful of dropping things like screws into the case. You also should wear an anti-static wrist strap to avoid damaging components with static electricity.

Wireless adapters have two modes of operation, infrastructure and ad hoc. Installation of adapters is usually very simple. Once you install or connect the adapter to the client PC, Windows (assuming you are using Windows) usually recognizes the new hardware and prompts you to insert a disk with the appropriate drivers.

Even if you aren’t using Windows, the configuration utility that comes with your adapter will lead you through the setup process and often automatically detects your access point and the channel that it is using. Manufacturers call the ability to automatically detect and select the channel frequency-agility.

Normally the software prompts you to select an SSID from a list of detected SSIDs. Assuming your AP is the only one in range, this will be a short list. You will then enter any other required information, such as encryption keys.

Note: Windows XP has a feature called Wireless Auto Configuration. This is a useful feature if your wireless adapter supports it Wireless Auto Configuration automatically configures your card to connect to a detected preferred network.

This means that you can have several saved configurations (home, work, coffee shop, and so on) and Windows XP automatically configures your card to connect when it detects those networks. It also can prevent your computer from accidentally connecting with another network (like your neighbor’s).

The software also may prompt you to select a data speed. This is the minimum speed required to connect to your WLAN. Usually your card performs this selection automatically, based on the signal strength that it detects. If your signal strength fluctuates you can set this speed manually to a signal level that your adapter can reliably detect. There also are good security reasons for setting a high minimum connection speed.

Adapter setup should be a relatively painless process. In the event that you do run into problems, review your documentation and visit the manufacturer’s Web site for updates and helpful troubleshooting tips.
