So another theory bites the dust. For months I've thought that if high-end compact cameras only packed bigger sensors, we would get better high-ISO performance and be able to use these devices for existing light photography in dim environments. But our first test case has not proven this theory to be true.

DP Review just analyzed the new Sigma DP1 compact that uses an image sensor that's nearly the size of a Nikon APS-C sensor, which is many times bigger than the standard 1 1/8" chip found in most compacts. You can see the size comparison on the first page of the DP review. Yet, in their wrap-up of the DP1's features, they write:

"While the DP1 can produce some brilliant results in daylight, it is almost completely useless in any low light situations. At higher sensitivities you'll find large amounts of chroma noise in your images, and you start losing detail. Turning on the flash won't help you much either, it is very low power and takes ages to recycle. Chances are you would not be able to focus anyway. The AF gives up completely once you dim the lights and there is no AF help light on the DP1."

Ouch!

So, this big Foveon sensor is no better in low light than my tote-around point and shoot. Of course, there could be other contributing factors to this, such as the Foveon technology itself, the supporting electronics, or some other thing that I just don't get. But the bottom line is, our first test case for putting a big sensor in a small camera fails to improve low light performance.

So, for now anyway, looks like I'll stick with my Canon G9. Maybe Sigma will go back to the drawing board and improve performance with the DP2.

Digital gear needs protection from excessive heat when working in summer weather. For these conditions, you may want to use a thermal bag to keep your gear from overheating. I like this eBags Crew Cooler because it has a second compartment on top where you can put your cool items, yet keep them separate from your gear in the insulated bottom compartment.

There are plenty of zippered pockets for accessories, dual handles, shoulder strap, and lots of storage (15 x 8.5 x 10.5 inches), yet the Crew Cooler only weighs 2 pounds.

The eBag isn't cheap ($39.99 on Amazon), but if you want a professional insulated bag that's also good for food storage, then it's worth the investment.

Post a Mini Review

Let us know what you think about either of these books. Post a mini review right here.

Dominique James has posted an interesting piece on Viveza's U-Point technology. I'm also a big fan of the work going on over at Nik Software. This latest plug-in for Aperture -- which is also available for Photoshop CS3 -- makes localized editing a snap.

If you're not a huge fan of channels and masks in Photoshop, take a peek at what Nik is up to. It might change the way you work. Oh, and one other thing. If you buy Viveza for Photoshop, the registration number works for the Aperture plug-in too, and the other way around. It's like getting a 2 for 1.

Eye-Fi Explore looks like a typical SD Card, but it's actually a 2GB storage and wireless device that can add geographic location labels to your images. In other words, maybe we finally have an easy way to geotag our images.

I haven't tested this yet, so I'm not sure how it works. But I am interested. If anyone has additional info, please post a comment.

Ring flashes can produce great lighting for portraits, either by themselves or part of a multi-lighting scheme. Expo Imaging recently released the Ray Flash: The Ring Flash Adapter that "creates a three-dimensional shadow-wrapped look around the subject. Because ring flash light originates from a circle around the lens, it produces a virtually shadowless look on the front of your subject, while producing a soft even shadow around the edges."

To put this new device through its paces, Strobist recently published a full review of the Ray Flash. The bottom line?

"...if you are mobile -- and especially if you like the TTL thing -- you have to give the Ray Flash strong consideration. And this design clearly took a lot of time and effort to produce. Not to mention a some very expensive mold design."
"For the people for whom it makes economic sense, the cost will be returned many times."
"I suspect that the Ray Flash will be a hit with the hipster wedding shooter crowd. It takes up almost no room in the bag, then you just slip it on when you wanna do the funky bride shot. You can do it at each wedding -- it's always new to them, right? This thing could make some cool reception pix, too, if you are into that kind of thing."

If you can afford the $300 price tag, Ray Flash is available directly from Expo Imaging

Adobe just released an update to Photoshop Express that includes integration with Flickr and "Save As" functionality. Plus, there's a new embedable player that allows users to post their Photoshop Express slideshows to sites such as Facebook, Myspace, and personal blogs.

You may have caught wind of this update earlier in the week when some sites reported about it. But Adobe had to pull it back on May 7 because they discovered a bug. By Friday, May 9, they had everything cleaned up and ready for users.

According to a report on the Stock Artists Alliance web site, "Orphan Works is back. Last month, the U.S. Congress held Hearings, making clear that the wheels were again in motion. Last week, it became official when new versions of the Orphan Works Act of 2008 were introduced by both the House and Senate."

If you're not familiar with the Orphan Works issue, it essentially means that if your copyright information gets stripped out of the metadata of your photo, and someone wants to use that image, they may be able to do so if it is determined to be an orphan work. SAA is looking to protect the rights of photographers by making sure this legislation isn't too loose. They have a nice piece on the issues surrounding this legislation.

This is something for all photographers to be aware of, not just stock shooters. Once your images are in the wild, you want to be sure you're given credit for the pictures you take. And if there is money at stake, you need to be part of that conversation. Learning about the Orphan Works legislation is important for all of us.

One of the things I like about Red River is that they sell directly to photographers, and they have an excellent customer service attitude. Plus the prices are fantastic! And they are one of the leaders in creating photo papers that are made from 100 percent post-consumer recycled content. This is a winning combination for TDS members.

Be sure to check out the Photo Paper Sample Kit for $7.99 with free shipping. Great to have you aboard Red River.
