JPEGs versus HEIF

Comparing HEIC and JPEG formats - The insets are 250x250 pixel uncropped excerpts from originals. 

HEIF (notice the F is not a C) is a file type for storing images.  HEIC is that type of file but is proprietary to Apple and used in iOS devices like iPhones.  The HEI portion stands for High Efficiency File and the F is for File format and the C is for Container.  This type of file has been around since 2016 or so.

JPEGs have been around forever (1992) and for many years has been the universal standard for creating and saving image files.  However, some new mirrorless cameras gives you the option to use HEIF format and most cellphones now allow saving your images in this format.

I can set my iPhone to take HEIC images, but it defaults to JPEG when using burst mode.  I only  learned this because I was photographing my game on Sunday and discovered my burst were JPEGS while my singles were HEIC.  

HEIF formats are technically better than JPEG formats because the former involves compression but no artifact creation - the files are lossless.  The latter also involves compression but do have artifacts associated with them - they are lossy in nature.  The difference is that JPEGS are universally available to all devices capable of working with images, while not all devices are capable of working with HEIF images.  Apples can use HEIC without problems and a Windows 11 machine can also deal with them effortlessly.  Windows 10, however, requires a patch to do so, otherwise, it can't read the file.  Android can open iPhones HEIF files and visa versa.

I learned a few things about these file types this weekend.  Cool.

Thanks for reading.

Harjit Bahia - Science teacher and colleague from Garibaldi died August 2, 2024

You will be missed Mr. Bahia.  You made a difference and we are sad you are gone. I keep in loose contact with my fellow retired teachers from Garibaldi Secondary School.  I talked with my long-time friend, Mike Lynch, today, and discovered that Hargit died over the summer.  Unbeknownst to him, he had an underlying heart condition and passed away after working out on his treadmill.  The date was August 2, 2024. I was shocked to hear this.  He was only 49 years old, turning 50 some 3 months later.  It was a shock to everyone, for he was loved by all who knew him.  As a teacher, Mr. Bahia was kind and fun.  He contributed to students in many ways and was always available to help those in need.   For myself, I knew him as a fellow science teacher and taught in the adjoining room to him.  He was always available to help, share ideas, and work together.  Easy to approach, I found that I could talk to him about anything and appreciat...

I found a black widow spider in a plant pot today

Image
The spider I found is a western black widow spider, one of three species of black widow that occur in North America.  The fact that this one has another red patch on the back of its abdomen above the spinnerettes tells us that it is an immature individual. The one thing that people know about black widow spiders is that they are extremely poisonous.  Their venom is something like 15x more toxic than that of a rattlesnake.  The saving grace is that there is very little venom injected from a black widow bite than what a rattlesnake can deliver.   The good news is that black widow bites seldom lead to death.  You are more likely to suffer nausea, muscle pain, and swelling around the bite.  Symptoms usually last only 12 hours or so.  Death may be a result in people with compromised immune systems or in the very young or the elderly.   In 2018, it was reported that there were 1015 cases of people bitten by black widows.  Of those, there ...

The passing of a generation

Image
Kathryn's mom and dad with our children, Josh and Leanne. A generation, for North America, tends to be between 20 and 30 years.  During that time a couple will give birth and raise children to see them repeat the pattern as they themselves have done.  Each generation has its own set of standards, values, and ideals based upon their experiences and culture, and some of that is passed down to their offspring.  What changes are the life experiences of the following generation and the new customs and ideals that are blended together as a couple becomes a family. Kathryn's mom passed away a few days ago, she was predeceased by her husband several years ago.  Both of them were the grandparents of my children, the mother and father of my wife, Kathryn.  It was my pleasure to know them and to love them as my own, for to me they were Mom and Dad.  And they were there to welcome my children into the world just as my children were with them in spirit when they left it...
