A basic guide to digital cameras

The future is officially in our present when it comes to technology and the advancements just keep rolling in. Videography, photography and everything in between aren’t forgotten when it comes to today’s continuous advancements. With DSLR cameras in households of professionals and amateur photographers all around the world and high speed imagery devices in several different genres of professions, designers and engineers behind the mechanics of these devices are on full speed development.

A photographer and DSLR cameraHere is a little more need to know information to help you get a little more insight on the ins and outs of the devises you may use at home. Digital single-lens reflex cameras are uniquely designed advanced digital cameras. The DSLR camera combines parts of a SLR camera and a digital camera back, this specialized design is the featured difference between a DSLR and any other digital cameras and recording devices. Frame rate or frame frequency essentially is the frequency rate where an imaging tool (such as a DSLR camera or a high speed imagery device) accurately produces consecutive images (frames). This general term is used when describing film and video cameras, motion capture systems, and even computer animation and/or graphics.

The standard for video is 24p (23.976 frames per second) which is standard for DSLR video recording devices. To ensure proper visual appearance there is a general rule of thumb when recording video with a DSLR video device, the shutter speed should be double the frame rate. That may seem like a mouthful of information, but it helps to know how a device really works to ensure adequate usability.

Advanced high speed cameras record details of fast mechanical movements and play them back in slow motion for adequate and relevant analysis. Just a regular high speed camera typically records over 1,000 frames per second into DRAM then reverses to slow motion playback for adequate studying purposes. There is a company called AOS Technologies which produces high speed imagery cameras and devices that are used for a wide range of purposes from crash testing all the way to defence application. Biomechanical analysis is just one of the top leading, and interesting, areas of expertise where high speed cameras are significantly making an impact. Movement sequences can be precisely recorded for analysis for training on body movement for medical purposes, video animation and or graphics, physical therapy and science. It’s safe to say that high speed imagery has and continues to assist in much of our world’s advancements in a vast spectrum of areas especially scientific purposes.

Technology is growing day by day and there are engineers eager and up for the challenge. We are extremely lucky to have such amazing tools readily available for everyday use.

How to find images for your website

There’s absolutely nothing wrong with taking a DIY approach to building your website. If you choose the right tools *cough* WordPress *cough* you can produce something that looks very professional without having to know web design in an out.

As with Creative Commons images, always check the usage rights of every image cautiously. You might be required to credit the photographer, or use may be forbidden in some situations.

Purchase cheap stock photography

It is all well and good looking for free pictures, but it’s often easier to invest a small amount of cash than to spend hours finding the right totally free image.

That is where websites like iStock Photo and ShutterStock come in. These vast repositories include thousands of pictures, most of which you can buy for just a few pounds. Sure, they can be frustratingly clichéd at times, but a bit of experimentation with what you search for can generally get outcomes. Expect to pay from £1 upwards for each image.

Ask permission

This is most likely your best option if you are looking for an image of a current occasion or specific individual to use with an article or blog post on your web site. Amateur photographers are often pleased to let their photos be utilised at no charge – if you ask nicely.

A good method to find pictures is through Flickr. For example, there are many David Cameron and Tom Cruise pictures to select from. As soon as you’ve found a photo you like, just use Flickr’s contact choice to send the photographer a message asking their permission.

Do be wary using photos of well-known individuals – whilst generally it’s okay to use them alongside news stories and other editorial, you will get in difficulty if it looks like they’re endorsing your item or service.

Take your own photos

With even cheap mobile phones able to create reasonable-quality pictures, you don’t have to be a pro to capture photos that are good enough for the web.

Even though the company is in all sorts of difficulty, you will find some good suggestions for taking better photos on the Kodak website.

Assuming you already own a camera, this method is practically free – and it holds other benefits more than stock pictures. For example, do you think website visitors would prefer to determine a generic image of someone on the telephone, or an actual member of your sales team at function in your workplace?
