A basic guide to digital cameras

Leave a reply Camille Mitchell

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.

Lumix Super Zoom TZ40 camera review

Here’s my overview of the Lumix Super Zoom TZ40 camera.

Housed in an ultra compact body, Lumix have packed into the TZ40 GPS, Near Field Communication, Wi-Fi and 20x Super Zoom.

Panasonix digital cameraThe 24mm ultra wide-angle 20x optical zoom lens is a Leica DC Vario-Elmar, which combines quality and versatility. Furthermore, Intelligent Resolution technology means that, even when using the zoom, deterioration of picture quality is kept to a minimum and is also available whilst in video-recording mode. Meanwhile, flare and ghost are kept to a minimum courtesy of the Nano Surface Coating of Panasonic’s black box technology.

A newly integrated 18.1 MP High Sensitivity MOS sensor provides high speed signal processing and high quality image recording, whilst new noise reduction and edge smoothing technology newly incorporated into the Venus Engine does exactly what it suggests. Meanwhile, a combination of the high-speed digital signal output technology, the light speed and the mechanical shutter realize full resolution 10 frames per second consecutive shooting.

Follow the simple guidance provided and the NFC technology and Wi-Fi connectivity allow you to connect the camera to tablets and smartphones by simply placing them in close vicinity. Then enjoy remote shooting, uploading and transfer.

The camera will also record HD videos which, courtesy of the 5-axis correction technology which can detect and compensate for operator movement, will seem like you shot them using a tripod.

The GPS function detects and records landmark, town, county and country information alongside photos and videos which can then be logged and reached quickly. For more information check out the camera on Panasonic’s website.

Integral Compact Camera Case Review

It’s been about two weeks since I last posted an article, and to get back into the swing of things, I am going to do a review.

Camera Case Review

The beauty of today’s review, is that it is a case that is suitable for the majority of compact digital cameras. In my most recent case review, I looked at a case for the BlackBerry Curve 8900, which was a great case that I am still using, however it wasn’t a general case for use with all phones, which meant it was more of a niche market product. The camera case I am going to review today, can protect most modern, small and medium sized compact cameras.

Integral Compact Camera Case

Integral camera case and memory cardThe case in question is an Integral Compact Camera Case, which (at the time of purchase) costs £16.99 GBP. You might be wincing at the price already, as you can pick up a reasonably good camera case for just a few pounds these days. So what makes this case special?

As you would expect, the case is secure. The case has a strong zip, with two metal pull tab sliders, so you can open and close the case with ease.

Inside the case, there is an additional storage pocked. I use it to store the batteries, although you can use it for anything really, a spare memory card, credit cards, whatever you like really.

The case feels very firm, yet the inside is softer to ensure that your camera doesn’t get damaged. I think the case would be better were it to have slightly more padding on the inside, as it is a multi-camera case, small cameras could potentially break easier, as the case is fairly roomy.

The case has a belt loop and a strap, so you can either wear it over your arm, attach it to your belt, or carry it in your pocket.

Additional Features

A fantastic additional add-in that comes with the case is a 16Gb SDHC memory card. Most compact digital cameras now support SDHC , and 16GB is a lot of photos! On one of its best settings, my camera can take around 4,000 photos, which is a lot! The memory card has a transfer speed of up to 20Mb per second, which is pretty fast, meaning that when taking photos, and downloading them to your PC, the memory card shouldn’t ever slow you down.

Overall I really like the case, it is simple and does the job of protecting my camera well. It is easy to carry around, and is reasonably sturdy, so that were I to drop it (not that I plan to) I think it should protect my device. 🙂

The camera case used in this review was provided by Love Cases, who have asked us to point you in the direction of their camera cases, so if you liked this review, you know where to get a case!
