Low Light Photography Guides

Dave Johnson has recently posted an interesting article on taking better photo in low-light condition. He suggests shooting at the lowest possible ISO all the time.

“In ordinary conditions, stick with the camera’s lowest ISO level, since that’ll give you the least digital noise. But when you notice that the camera is recommending a really slow shutter speed (less than about 1/30 second for handheld shots with a point-and-shoot), crank up the ISO. Just remember to drop it back down to the lower value when you’re done, so you don’t accidentally capture a month’s worth of pictures at ISO 800.

Another thing to keep in mind: Most digital cameras don’t allow you to adjust the ISO, or any other setting for that matter, when you’re in Automatic Exposure mode. To tweak the ISO, you’ll want to be in Program, Shutter Priority, Aperture Priority, or a Scene mode.”

Sigma AF 10-20mm f/4-5.6 EX DC HSM: The images also exhibit great clarity and impressive definition of intricate detail. This Sigma lens seems to be optimized for the very finest results at focal lengths from about 10-14mm at most apertures. By 15mm, edge sharpness is a bit softer, although central sharpness remains very high.

Fujifilm Cuts 5,000 Jobs

Bloomberg reported that Fujifilm will eliminate 5,000 jobs and shift some production to China from Japan.

“Fuji Photo’s plan symbolizes an end to the film camera era,” said Hiroshi Chano, who helps oversee $6.7 billion at Yasuda Asset Management Co. in Tokyo. “The digitalization of the camera industry occurred at much faster pace than I expected. Reorganization will be a painful process for Fuji Photo.”

By taking these restructuring steps, we hope to reduce fixed costs and secure stabile profits in our imaging solutions division,” the Tokyo-based company said in the statement. “

High-Speed Shock Wave Photographs

American Scientist Online has recently posted an article with cool images of high-speed imaging of shock waves, explosions and gunshots.

Shock Wave Photograph

This full-scale schlieren image shows the discharge of a .44 Magnum revolver. Two spherical shock waves are seen, one centered about the gun’s muzzle (the muzzle blast) and a second centered on the cylinder. The supersonic bullet is visible at the far left. This weapon produces a bright muzzle flash and a cloud of products of gunpowder combustion that envelops the hands of the shooter. Such high-speed images help forensics experts understand the transfer of gunpowder traces to the hands when firing a gun.

Canon PowerShot SD430 – Review @ CNET

Shams Tarek reviewed the Canon PowerShot SD430 and gave it 7/10 (very good) at CNET. He wrote:

“Rounding out the Canon PowerShot SD430′s Wi-Fi feature set is the ability to print wirelessly without the use of a computer. The camera comes with a Wi-Fi adapter that plugs into a printer’s PictBridge-compatible USB port, traditionally used for wired camera-to-printer connections. Unfortunately, it works with only Canon printers at the moment.

If you don’t have a yen for remote control or wireless printing, then save yourself some money and get the PowerShot SD400. But if the wireless remote control option sounds like the solution to a problem you have, you’d be wise to give the Canon PowerShot SD430 a try.”
