We use ND Filters to block certain percentages of light from entering our cameras, thus lengthening the shutter speed for a more dramatic effect. Calculating the amount of time needed to compensate for an ND filter isn’t rocket science and if the filter is light enough, the camera can do a pretty good job of it on its own. However, when you start using darker filters (>3 stops), it might be a bit difficult for the camera to accurately meter (if at all) and thus it’s a good idea to at least have an idea of how to calculate shutter speeds based on the ND filter (or filters) being used. I’ll be going over the math behind the voodoo and explain it using formulas and simple concepts.
Long Exposure photography is an art all on its own. When you use ND filters, the amount of light entering the camera and touching the sensor changes dramatically. Luckily, figuring out how much to compensate isn’t something to worry about with the NDTimer app from the iOS App Store.
Any landscape photographer worth his or her salt will tell you that national parks are a mecca of awesomeness when it comes to photographic potential. In other words, they don’t die and go to heaven, they die and go to [national park name]. National Geographic knows that the United States is loaded with awesome parks and decided to showcase them in their free app National Parks by National Geographic. It’s a mouthful, but all you need to know is it will describe some of the best parks in the country in great detail, with additional parks being added all the time.
Update: I understand not everyone who reads this blog is an iOS user. To cover you, I’ve included a list of links for the national parks featured in this app. Information provided by the National Park Service. I’ve also included a link to NatGeo’s National Parks Web site containing a load of information there, as well.
If you’re a photographer in any sense of the word, you likely use your camera quite a bit, I know I do. It performs for us day in and day out without question and was one of the best investments we’ve ever made. One thing we tend to neglect is regular cleaning maintenance of our equipment. Too often are we spending time in Photoshop cloning out dust spots and in my case, a hair that kept making its way into the frame. It’s annoying and not something we have to live with. Over the next few minutes I’m going to go over some basic camera and lens cleaning tools and how you can make them work for you, too, so your lens and body stays fresh, clear, and ready to go.
I am going to start with this simple statement: KelbyOne (formerly KelbyTraining) is an awesome service to learn about Photoshop, Lightroom, Photography, and a whole host of other tools. I have personally learned quite a bit from this site and I wanted to share with you some of its best features, in hopes that you’ll enjoy it, too. KelbyOne is part of the Kelby Media Group, run by the incredibly talented photographer Scott Kelby. KMG also oversees Photoshop World and NAPP: the National Association of Photoshop Professionals and it’s magazine: Photoshop User. A library of books have come out of Kelby Media Group from Photoshop to design to photography, and the video courses on KelbyOne wrap up the whole package. Not to mention: discounts… who doesn’t love saving money?
