You have just finished taking photos from your latest vacation.
Your Images Are High Resolution
You used the latest Sony A7 III Alpha mirrorless camera so your images are high resolution full frame 24 MP captures. Now you want to upload them to the Internet on a photo sharing website and view it from your web browser. Read more
There are different techniques to achieve HDR in photography.
The most common is using multiple exposures to create a composite image that brings out the details and contrast. Another technique can be done in post, called tone mapping or local tone mapping. This does not require the use of multiple exposures, so it can be done on a single exposure. Read more
Humans and machines differ in how they act in so many ways.
A Form of Intuition
Yet there have been developments in AI that have led to not only more intelligent machines, but also it seems like they have developed a form of intuition. It was an insight learned from Google’s DeepMind research that involves a super computer that used AI called AlphaGo. It became a master in playing the ancient game of Go, even defeating the best human players in the world. Then a successor was built called AlphaGo Zero which defeated AlphaGo. It seems it had developed its own strategy based on what appears to be intuitive thinking. That was something believed only humans can have, not computers. Read more
Fast Super-Resolution Convolutional Neural Network (FSRCNN) is an imaging technique that upscales the resolution quality of a digital image.
Real World Application
It is based on a shallow network design that is faster and clearer than its predecessors in reproducing the image. This technique was described in this publication from the Cornell University Library of work by researchers at CUHK (Chinese University Hong Kong). Its real world application in the world of digital imaging shows potential for creating high quality images that have been “super-scaled” from their original size. FSRCNN shows it has a much higher image quality and shorter run time as well. Much of this article is based on research work by SH Tang. Read more
Pixel count in digital photography does matter, and it depends on the image you are creating.
High Resolution Cameras
Most smartphones now have high resolution cameras that are capable of at least 6 MP (megapixels) which is 6 million pixels. When looking at camera specs MP is also something manufacturers advertise. The pixels are “picture elements” which determines the quality and resolution of your photos. The more pixels the > size of the photo, the more quality and detail available for the photographer/retoucher to work with. Less pixels means < size and less detail and quality. The photo undergoes further loss in detail if compressed using a format like JPEG. The image resolution is the full size of the photo measured as Width x Height = MP. When shot in full RAW format, the details are preserved and can be edited in a non-destructive way that keeps the original image but allows for export to a different format for the final edited version.
The pixel count is determined by the digital CMOS sensor in the camera. There are different types and here are some comparisons. Read more
