Firewire. Words

FireWire, also known as IEEE 1394, was designed to be a universal interconnect, eliminating the need for many different input/output connectors. The 1394 bus is a versatile, high speed, and inexpensive way to connect a wide variety of consumer electronic devices such as computers, digital camcorders, hard drives, scanners, printers, audio recorders, and videoconferencing cameras. With FireWire, it’s possible to connect up to 63 devices together. When 1394.1 bus bridges become available, it will be possible to connect over 60,000 devices together on a common bus.

There are currently two standards: the original FireWire, now referred to as FireWire 400 or IEEE 1394, and FireWire 800 or IEEE 1394b. As the names imply, the maximum speed of FireWire 400 is 400 Mbits per second, whereas FireWire 800 tops out at 800 Mbits per second. FireWire 800 is backwards-compatible, and unlike USB the FireWire bus speed is not diminished when a slower FireWire 400 device shares a FireWire 800 bus. The maximum cable length is currently 4.5 meters or around 15 feet.

There are three types of connectors associated with FireWire. The standard FireWire 400 connector for ports found on Macintoshes is a six-pin connector that looks like this:

Four of the connectors on the six-pin connector are used for the transmission of data, while the other two provide power to devices that are bus powered. FireWire can provide up to 45 watts of power through the connect, thereby eliminating the need for separate power supplies for peripheral devices.

Another popular FireWire 400 connector, found on devices such as camcorders and Windows PCs, is the 4-pin connector:

The four pins provide a data path to and from the device but not power.

Finally, there is the the 9-pin FireWire 800 connector:

Three of the pins provide power and the other six provide data channels for external devices.

Talking To Yourself

I don’t know what your dayrate is, but I always measure the difference in price in terms of how many additional billable days it is ie. IQ140 to IQ 160 is about 2 days fees.
So, the question becomes, “Over the expected service life of this back, 3 years or so, can I manage to find just 2 additional billable days”.
The answer is usually, “Hell yes!” –– online advice

My Suggestion

Ask not, what is your day rate, rather, ask, what is your daily profit? Use that to figure the dollar assignment for new purchases.

digital Divide

Is it better to shoot bigger, or more? Is there a better or only a difference? Is film always better than digital, never, sometimes, maybe only for the time being?
If you were shooting film decades ago, you would have had access to 110 and 8×10. The 8×10 would have had film available from no less than 5 manufacturers each offering multiple emulsion types in B&W and in color. You could have made choices for type of light. Indoor, outdoor, tungsten, strobe. Oh, that would have included multiple types of tungsten.
At one point a film supplier in Manhattan listed more than 80 film choices for 8×10. Truly a golden age, as long as you could decide, then work. The task was made easy only by knowing what you intended to do with the image. Sometimes that was the harder part.

Legibility vs. Detail

Which brings us to the central question of the photographer picking among technical options. I assume that you have the basic craft skill and so the choice becomes aesthetic and financial. I also assume that you want to own your tool. Most artists do, because of the feeling of commitment as well as the advantage of spontaneous action. In photography, in a large enough town, or with enough credit, you can always rent, either locally or by the internet.
What makes this image so effective?

Is it the detail? Look closer. There is detail, but not as much as the rabbit had. Nor is there as much detail as would be captured with today’s best glass and chip. Yet the image is legible. More importantly it answers “if looks could feel” questions. This image captures the imagination of the viewer. The rabbit has both soft fur and coarse fur.
This could sell children’s clothing, furniture, even makeup. It, of course, wasn’t designed as an ad. it was meant by the artist to be complete, not edited.
It presents itself completely, legibility, with only enough detail to achieve the goal.

The Need Of ADs To Crop

This sheet shows the crops to photographs of Tony Ray-Jones. The original photographs were made by Ainslie Ellis in 1970.
These grease pencil marks are turning the square format into the verticals used by magazines. They turn them into portrait mode, used by magazines. 393EFDD5-7183-4DB5-907A-AA951D7BF896.jpgThe natural order of cameras is landscape format. This is how our eyes are arraigned and it gives us our peripheral vision. The 120 square of Hasselblad and Rollei makes either published form possible. Different art directors or different purposes give different crops from the simple square. Since the 120 neg is so much bigger than the 135, it gave flexibility to the editor without giving up to grain.
