- HEIC / HEIF / HEVC
- The image format is called High Efficiency Image File Format (HEIF) and it’s based on High Efficiency Video Coding (HEVC). HEVC is also known as H.265 or MPEG-H Part 2.
- After Apple released iOS 11 in September 2017, the default photo file format on the iPhone and iPad was changed from the ubiquitous JPG to a file format known as HEIC. Apple was the first major manufacturer to introduce HEIC, and it created some ripples that are still being felt today.
- How to Convert HEIC to JPG | PetaPixel
- RAW format
- Camera Requirements (= wish list): (digital still camera)
- Sensor - see below
- MegaPixels - At least 10 MP
- Lense
- Superzoom 20x-30x optical zoom (NOT including digital zoom!!)
- Internal threads to allow adding a filter (e.g. UV filter)
- optical image motion stabilization - camera shake compensating system (essential for high magnification)
- Video, HD video recording - at least 1080p video
- support for RAW format
- GPS = Determine and record the shooting location for every photo. After downloading the images to a computer, the user can view all of the geo-tag data (latitude longitude) with imaging software or on a map at Picasaweb or Panoramio or Google Maps.
- LCD screen (2.5" or more)
- ultra-high resolution 3.5" OLED screen
- eye-level viewfinder
- touch-screen operation
- small, easy to carry
- I/O
- USB3 input/output (and perhaps FireWire-IEEE1394, if only USB2 is available)
- HDMI output
- Remote release port
- replaceable AA cells (not a proprietary battery that needs a proprietary charger)
- face detection
- warranty (>=2 years)
- waterproof
- 3D panoramic photo & 3D photos or 3D HD movies

- Phones
- DSLR
- Sensor - see below
- SLD = single lens digital = mirrorless = (new category that started in 2009/2010)
- electronic viewfinder (EVF)
- SLR = single lens reflex = with a reflex mirror or pentaprism
- have interchangeable lenses
- SLRs/SLDs do not have superzoom lenses - WHY??
- Shutter lag = response time
- SLRs have less/no? shutter lag
- 6 (2-11) fps continuous drive mode (or burst mode) - at full resolution - (frames-per-second)
- fast focus times
- AF tracking = auto focus to keep the subject in focus
- Continuous Tracking autofocus
- advanced Intelligent Auto mode
- 14-lumen projector (optional)
- Sensor
- SLRs have a larger sensor size than superzooms - WHY??
- Why not use better sensors in superzooms?
- a small sensor is what allows such a long focal range lens to be relatively compact
- a larger sensor means larger lenses which lessens the size advantage that many point and shoots have

- Exception: In 2005 Sony came out with the CyberShot DSC-R1. It had a CMOS ASP-C class sensor. 10.3MP, 5xOpticalZoom, 3888*2592, RAW&JPEG - currently about $900, if you can find it on eBay.

- ISO = the International Organization for Standardization (ISO)
- Note that the smaller sensors are measured in inches (e.g. 1/2.5")=(5.76mm*4.29mm), but that value is then converted into the metric equivalent (24.7 mm2).
