Ask David: When do I use different shutter speeds?

Ask David: When do I use different shutter speeds?

Your camera is an amazing creative tool. That’s not really intuitive to a lot of beginners, because cameras are so good at recording reality. But the fact is that you can use your camera to manipulate reality just as you can use it to recreate reality and the simplest creative tool your camera has is shutter speed. Shutter speed works in two directions–you can either slow it down or speed it up. Use a slow shutter speed to emphasize movement. Use a faster shutter speed to freeze movement. So how do you decide when to choose a slow shutter speed, and when to choose a faster one?

Ask David: What’s the best way to change my camera lens?

Ask David: What’s the best way to change my camera lens?

What’s the best way to change lenses? What happens if I get dust on my lens? What about on my sensor?

The best way to change your lens is as fast as you can without damaging your gear. Minimizing the amount of time the camera and back element of the lenses are exposed to the elements minimizes the potential for dirt and other particulates to get into your camera body. Don’t change your lenses in a rainstorm, while cleaning out a dusty attic, or on the sand at the beach if at all avoidable. Those environments can wreak havoc on the internal workings of your camera.

Here is my typical lens change procedure, step by step:

Ask David: Should I purchase an off-brand lens for my camera?

Ask David: Should I purchase an off-brand lens for my camera?

Off brand, or third-party lenses, have both perks and pitfalls. Some photographers will swear by third-party lenses, while others swear they are not as sharp or reliable as a proprietary lens. The first and probably the most important advantage of an off brand lens is the price. Quite often, third-party gear companies make lenses that are similar in capability to those produced by major camera companies at a fraction of the cost, especially when you get into higher end or more specialized lenses. For example, a Canon 24-105mm f/4L USM lens retails for about $1100, while a very similar lens by Sigma retails for $899.

Ask David : Should I Purchase a 16-270mm lens?

Ask David : Should I Purchase a 16-270mm lens?

I was recently asked this question: “I have a 18-55 mm and 75-300 mm lens. I am considering buying a 16-270 mm. Is this a good idea?”

My first instinct is to say no. Between the two zoom lenses you already have, you cover pretty much all of the ground a 16-270mm lens is capable of perusing plus some. Also, as a rule of thumb, a range with a longer lens (ie 16-260mm) is not normally going to produce the same quality as a lens with a shorter zoom range (ie 18-55) or a prime lens.

I would look into lenses that cover ground my current gear doesn’t but ultimately, it truly depends on the type of photography you shoot the most. Let me explain.

Ask David: The scourge of photography: Blurry Images

Has this happened to you? You pack up your camera and go to a football game. It’s a great game, and you’re sure you’re capturing some fabulous images. You’ve got a perfect, clear view of the field, a good telephoto lens and shots of all the best moments. When you arrive home, you can’t wait to see what you’ve got. You load the memory card up on your computer and you open up your photos in Photoshop and…

They’re all blurry. Every single one of them. What happened?

Ask David: Reducing Blur In Pet Photos

Ask David: Reducing Blur In Pet Photos

No one can argue that camera lenses and cute dogs go together like peanut butter and jelly. After all, who doesn’t want to capture memories of their dog from puppy to adulthood? Our dogs’ photos go on the mantel, in photo albums, and on our walls just like the rest of the family’s photos do. But, photographing your pup can be a bit of a challenge, as one reader found out. After a few valiant attempts at it, Ramona Samoila e-mailed me her photos and asked for an analysis. Here’s my response, and the happy ending.

Do I need to get permission from the people in my photos?

Do I need to get permission from the people in my photos?

There is something fundamentally weird about being a street photographer. Your job, whether you like it or not, is to stick your nose in other peoples’ business. It goes without saying that you can create a much more candid looking image when people don’t know you’re photographing them. But is this legal? More importantly, is it ethical? Here’s how I approach street photography.

Should I purchase my next camera from a grey importer?

One can’t help to resist the allure. Imagine what you could do with that new camera, especially at the much lower price point. Grey importers operate in… well… a grey area of sorts. Their business is totally legal, but they sometimes can’t offer the same protection that you would get from an authorized retailer. So is it worth it? Should your make your next purchase from a grey importer?

Why Don’t You Tell Us Which Settings To Use?

Hey guys. I just want to start by thanking you so much for your feedback on all of my articles. I’m excited that they’re helping you out as much you say they are. Over the last few years, I’ve gotten a bunch of fairly common questions. More than one of you has wondered why I don’t give out specific camera settings in my articles. By that I mean telling you exactly which aperture, shutter speed, or ISO speed setting to use to get a certain photo. Hopefully I can clear things up by explaining why I can’t do that. Rather than just being a nay-sayer, I’ll also tell you how YOU can find the appropriate camera settings to use for your photos.

Ask David: Can I Put RAW Files and JPEG Files on the Same Memory Card?

Ask David: Can I Put RAW Files and JPEG Files on the Same Memory Card?

A lot of us like to shoot in two different modes. If I’m shooting fast pace sports like tennis or racing, I like to use JPEG mode because it allows me to take a longer burst of photos before my camera has to start sending the images to my memory card. When I want a little more control over the final result, I shoot in RAW instead. I recently received a question from one of my readers. If it okay to keep RAW files and JPEG files on the same memory card? The short answer is YES. Now here’s why.

Should I Set The Sharpness Level On My Camera?

Should I Set The Sharpness Level On My Camera?

Your camera does a lot more to your images than you think. Just as you take a picture, your camera adjusts the white balance and the sharpness for you. How much it does this depends on the settings you give it. With that, many readers have wondered if they should even bother setting the sharpness level on their cameras. Is it worth it, or does it just end up giving you a lot less freedom later on?
