The Best Action Cameras for 2019

The Gopro action cameraAction cameras are small, lightweight, wearable, mountable, portable, and sometimes waterproof. They're useful because you can mount them to pretty much anything—from skateboards, surfboards, bicycles, and drones, to helmets, body parts, and even your pets.
Besides price there are other important points to consider when choosing an action camera including:

  • Frame rate and resolution
  • Waterproof specifications
  • Mounting features
  • Ease of controls

Optimizing Images for the Web

Images often form a large and important part of web pages. They may highlight a news story, illustrate items on a retailer's site or form a gallery of travel photos. However, unlike plain text, images consume much more bandwith to get displayed on a mobile phones and computers. Consequently web designers may use a range of techniques in an effort to reduce the file size on images. JPG, GIF and PNG image file formats have been the most popular with web designers for many years, while SVG is now gaining greater acceptance. Each format has advantages and disadvantages so the choice often depends on how the image is used on each webpage.

Equally important is optomizing images to be responsive to viewing on screen sizes ranging from tiny mobile phoned to huge TVs. Various responsive options are available for this task.

The following two large images are both 800px wide by 600px high but have very different file sizes while the third image is 400px by 300px so has a much reduced file size.

koala large

The file size of this high resolution image is 1143Kb so should be used with caution.


koala 800

However, the file size of this very acceptable image is only 29Kb or about 97.5% smaller.


koala 400

While the file size of this smaller image is just 9Kb and may be quite suitable.


Making an image responsive for all screens

The next three images are actually the same small 300px by 128px image file.

Small logo

The first image is not responsive so will show at this size on all screens.

The following two are responsive images and will display bigger on larger screens but will still respond correctly for small screens

Medium image

One simple method to make an image responsive is to wrap the image within "styled" span tags as used here:
<span style="display:block;max-width:523px;margin:5px auto"> Image goes here </span>

Large logoThis image is set to display up to a max-width of 800px for larger screens. Images may also be styled with both minimum and maximun widths if this is more appropriate.

Best Camera Phone 2018: What's the Best Smartphone for Photo & Video?

At TechAdviser we test the cameras on the five best phones on the market to see which has the best photo and video skills. These are the best camera phones of 2018.

The Best Smartphone for Photo & VideoFlagship phones have got to the point where raw performance doesn't really need to get much better, and so they are differentiated by their design, battery life, unique features and photography capabilities. We're focusing on the latter here, given that for many people a smartphone now replaces a physical camera. Our aim: to discover what is the very best phone camera money can buy, for photos, videos and even selfies.

We’ve tested and compared five phones with the best cameras currently available: iPhone XS Max, Galaxy S9 Plus, Google Pixel 3, Huawei Mate 20 Pro and the Huawei P20 Pro. We've included the P20 Pro as well as Mate 20 Pro because it's still a current phone, sold alongside the Mate 20 Pro. The reviews apply to the iPhone XS, Galaxy S9+ and Pixel 3 XL since they have identical cameras to the XS Max, Note 9 and Pixel 3 respectively.

You won't find every flagship phone here, as we're including only those which have cameras good enough to be called "the best". That isn't determined by specs or features, it's judged by the quality of the photos and videos they produce. It's why you won't find the Sony XZ2 or OnePlus 6T here, among others.

Image Composite Editor - Free from Microsoft

Logo of Image Composite EditorMicrosoft Image Composite Editor is an advanced panoramic image stitcher. Given a set of overlapping photographs of a scene shot from a single camera location, the application creates a high-resolution panorama that seamlessly combines the original images. The stitched panorama can be shared with friends and viewed in 3D by uploading it to the Photosynth web site. Or the panorama can be saved in a wide variety of image formats, from common formats like JPEG and TIFF to the multiresolution tiled format used by Silverlight's Deep Zoom and by the HD View and HD View SL panorama viewers.

Imaging Resource's New Comparometer

Logo of image resources pageThis tool now lets you compare reference images from digital cameras side-by-side. These images are JPEGs straight from the camera, and were taken under carefully-controlled conditions, to provide valid comparisons of camera capabilities in actual shooting situations. By clicking on and zooming into each image, you are able to closely compare a variety of indoor and outdoor images or the test patterns provided.

You can also download the images (using your browser's "save image as" function) and output them on your own printer, to see how the cameras involved will perform in your application. (See the copyright notice first though!). Check out the Comparometer now...
