How To Photograph Fireworks

Just two days away from the Fourth of July. Some of you may be watching fireworks with a camera on hand. National Geographic has some photography tips on how to photograph fireworks.

Set your camera to manual mode. Use ISO of 100, f/11, and 1/2 second. If it’s too dim or too bright, you can vary the shutter speed but keeping the aperture the same.

And lastly, don’t forget to post your best photo online.

Nikon AF-S NIKKOR 50mm f/1.4G

I have been shopping around for a prime lens for my Nikkon D90. I was looking at the Nikon AF-S NIKKOR 50mm f/1.4G. It’s super fast and it works great in low light. It’s a great walk around lens as well. In addition, it also takes great portraits and landscapes. You can find a find several reviews of the Nikon AF-S NIKKOR 50mm f/1.4G at

Testfreaks is a great site if you are doing comparison shopping. They collect product information and reviews from several thousand sources. You can practically find any electronic product you want at testfreak.

So, I’ve been reading hundreds of product and user reviews of the Nikon AF-S NIKKOR 50mm f/1.4G. Testfreak rates it at 9.4. The cheapest price is $429 at Amazons. Maybe one day, I’ll make the bold move to purchase this piece of glass. At the moment, I’m still using my 18-200mm VR lens, but I can’t wait to work with a 1.4 50mm prime lens.

In the meantime, it’s cold and rainy in Northern California. What happened to Spring?

Difference Between Nikon G and D Lenses

While doing research for a Nikon 50mm lens, I found out that Nikon offers two types of lenses, the G and D. I found this forum discussing in detail the differences between the two types.

Essentially the G is the cheaper one of the two since it’s made of cheaper plastic. The G also doesn’t come with an aperture ring. You’ll have to set the aperture settings in your camera’s body. This means, you can’t use the G on older cameras.

I’ve been interested in acquiring a 50mm prime lens to go with my D90 camera. A 50mm lens, I think, is ideally suited for portraits, low light and bookeh photography. Speaking of forums, Dpreview is still one of my favorites. Although, I’m not a frequent visitor.


Here’s a nice article about gPhoto, a command line program in Linux capable of intereacting with your digital camera. It can read your camera settings or download images to your desktop. Nikon and Canon have their own proprietary programs, but they run on Windows. gPhoto will work with a good number of cameras. The writer on this article tested on his Nikon D80. I have a Nikon D90. Interesting. I might as well check this program and see what it can do. Since the gPhoto runs on the command line, the possibilities are endless from scheduling backups, resizing images to creating thumbnails.
