How Is An Image Captured By a Camera?

Photography has become a part of our lives. We’re taking images every day, sharing them with friends and family, and quietly encouraging others to do so without even realizing it, resulting in an incredible amount of photos being taken globally.

Pressing the shutter release button starts a chain reaction inside a camera, leading to an image being recorded. It’s a series of events that happen one after the other inside the camera, all triggered by pressing the shutter release button. It’s like a domino effect – smooth and efficient.

Ever wondered what exactly transpires inside a camera during that process of image-making? Did you ever want to know how a camera captures an image? Today, we’ll learn all about that and more.

How to Use Your Phone for Capturing Videos of Adventure Sports

There are more tools and accessories to experience and record extreme sports than ever before — especially if you’re looking for a GoPro alternative. While GoPros are still great tools for recording adventure sports, you can now get accessories for your phone that allow it to fulfill the same purpose.

So, rather than having to buy a super expensive separate device, you can just get some extra tools to build on what your phone can already do. After all, modern phones are equipped with some of the highest quality cameras around. Being able to use them for extreme sports lets you really take advantage of what they’re capable of.

Tiny Time-Lapse Digital Camera

Pet

This is kind of a neat idea. It’s a camera called the “Pet’s Eye View” that you clip to your pet’s collar. It takes still photos on an interval timer, like a security camera, so you can download them at the end of the day and see what your pet has been up to.

That might make a neat time lapse video.

They say it’s for pets but I bet it works equally well on children. Let’s see… if I stick one to each kid maybe I’ll finally find out who’s been leaving the kitchen such a mess…

Review: The Flip Mino HD Video Camera

I really like the Flip video cameras. I reviewed the original Flip Mino back in June and recommended it for anyone who wanted to shoot more than a couple of minutes of video at a time or who wanted to reserve the space on their camera’s memory card just for pictures. The Flip Mino is a handy, compact, easy to use video recorder. And the Flip Mino HD (Amazon) is virtually identical in every way except one—it records 720p HD video.

Everything I liked about the Flip Mino I like about the Flip Mino HD. The body and controls are identical. You can’t even tell them apart visually except for the “HD” logo on the back. They operate exactly the same and feel exactly the same in my hand. Everything I wrote in my earlier review about the Flip Mino applies to the HD version. So let’s get on to video quality.

The video and sound quality are quite good. Video is recorded in H.264 format at 30 frames per second. Audio is recorded in AAC format at 44.1 kHz. The average bitrate is about 9 Mbps which lets the Flip store about 60 minutes of video on its internal 4 GB memory.

Review: Nikon D90 first impressions

On semi-impulse I bought a Nikon D90 kit last Thursday from Amazon after nearly four years with my trusty D70. I sat down with the manual over the weekend and got to know it a little better. There are plenty of great in-depth reviews of the D90 out there with tech comparisons and sample photos. This is not one of those. I’m just going to give you my first impressions of the D90, especially things about it that made me smile, from the perspective of a D70 upgrader:

  • Live view! Giant LCD! 6.7x image review zoom! Awesome. The D70 screen looks like a postage stamp now.
  • It is perceptibly faster and lighter.
  • I turned on the viewfinder grid, turned off the focus beep, and switched to selected area for focus because that’s how I roll.
  • The default image processing settings are fairly neutral and true to life. In Flickr terms: boring. There’s nothing wrong with that, per se, but I’m not particularly interested in absolute truth, photographically speaking. I prefer my photos to have a little more pop so I adjusted the default to Vivid which boosts both the contrast and saturation.

Review: The Flip Mino Video Camera

The Flip Mino video camera (www.theflip.com) could be the perfect complement to your digital still camera. I received a review copy of the Flip Mino this morning (sorry, no giveaway—it’s going back to Pure Digital soon) and within minutes I was making videos. See gallery and sample video at the end of this review.

Just about every consumer digital still camera I can think of has the ability to capture videos. And videos from the Mino aren’t going to wow you with their quality. What sets the Mino apart (I think it’s pronounced “minnow”) are it’s ease of use, size, and that it can capture up to 60 minutes of television quality video (640×480 @ 30 frames/second) onto a 2GB internal memory. It is a device laser-focused on doing one thing and doing it well: creating video for viewing on the internet. Think YouTube and mailing videos to grandma.

My Nikon D70 has no video capability at all and our Canon Elph, while respectable in the video arena, doesn’t have the juice to record a lot of video on a single charge. Plus, since video shares space with stills on the same memory card,

Review: Nikon Coolpix S550

Before you even take it out of the box the Nikon Coolpix S550 looks cool (mine looks especially cool being “cool blue” coloured). But while looking good is nice the important thing is how it performs. Nikon give very simple instructions for getting started with your camera, step one in the quick start guide is, no joke, “remove the camera from the box”! This might give you the impression that this camera is only for first time photographers and people who frequently try to use electronic devices without removing the packaging. Whilst the S550 would be a good camera for both of those consumer groups I’ve been testing it out as someone with a reasonable amount of digital photography experience and so far, to borrow a phrase from McDonalds, I’m lovin’ it.

Using the S550 on the Brooklyn Bridge in NYC.

It is fantastic to have a camera that fits in my pocket! Nikon markets the S550 as having the “smallest body among competing compact cameras” and it certainly is small for a camera with so many awesome features.

Make a pinhole camera for Worldwide Pinhole Photography day

Trying your hand at pinhole photography is easy and can be a lot of fun. Pinhole cameras pre-date autofocus and megapixels. They hearken back to a simpler time when a camera was literally just a box with film in the back. Photos made with pinhole cameras exude a fuzzy, low-fi charm that’s hard to resist. That said, it’s not for everyone, but I hope you’ll give it a try. If you’re anything like me, you’ll feel a little magic happening when you see that first photo. It’s sort of like stepping back in time. Have I convinced you? Do you have 30 minutes to spare? Read on to find out how to get started.
