High Definition Photography is an image codec that gives a high-dynamic-range image encoding while requiring only integer operations (with no divides) for both compression and decompression. It supports monochrome, RGB, CMYK and even n-channel color representation, using up to 16-bit unsigned integer representation, or up to 32-bit fixed point or floating point representation, and also supports RGBE Radiance. It may optionally include an embedded ICC color profile, to achieve consistent color representation across multiple devices. An alpha channel may be present for transparency, and Exif and XMP metadata formats are supported. The format allows decoding part of an image, without decoding the entire image. Full decoding is also unnecessary for certain operations such as cropping, downsampling, horizontal or vertical flips, or cardinal rotations. All color representations are transformed to an internal color representation. The transformation is entirely reversible, so, by using appropriate quantizers, both lossy and lossless compression can be achieved.
High angle refers to the situation where the camera is above the subject and looking down. From this perspective, the subject seems weaker, smaller, or more exposed. In storytelling, film, or portrait photography, it's frequently employed to elicit emotion, portray power dynamics, or provide visual interest.
Any digital camera is a good start, HD doesn't really pertain to still photography anymore. Only video
High key lighting photography is a technique where the scene is brightly and evenly lit, with minimal shadows and a predominantly white or light background. This creates a bright and cheerful atmosphere in the photograph.

The modern definition of photography is the process of producing images. This also includes, the process of taking or producing a photo.

Photography is the process of taking pictures with a camera - it's the definition of the word. Without a camera of some sort, it's not photography.

High key photography is a technique that involves capturing images with predominantly bright tones and minimal shadows. It can be effectively utilized by using a well-lit environment, overexposing the image slightly, and using a light color palette to create a clean and vibrant look. This technique is often used in portrait photography and product photography to convey a sense of positivity and energy.
