iPhone camera 12 mp images compared

iPhone 11 was used to create the above images.

I will be writing a learning guide on cell phone photography.  In order to do that, I thought it prudent to purchase an iPhone, and so, for $400, I bought my very first Apple phone.  I have been playing with it a bit and today did some photos comparing the images it provides.  There are three lenses, the first three images above and the resulting crops (follow the arrow) were made with the 0.5x, the 1.0x, and the 2.0x lenses.  These are called optical zooms or images because the image produced is exactly as the sensor sees it.

The last image was magnified by the camera's software using a process called interpolation.  The same lens that created the 2.0 times image (3rd from left) created the far right shot, which then was cropped to produce the relative enlargement.   

The first two images are relatively clear but the third one is a bit off.  I think that the focus point was in the wrong place which resulted in the lack of clarity.  The final image shows considerable artifact distortion from the interpolation done to the image.  You can enlarge (zoom in) the image to capture it by touching the screen with two fingers and then spreading them apart.  You can thus magnify the shot up to a 6x value (a 300% increase in magnification), but you would get the same quality by taking the 2x magnification and enlarging it on a computer.

I put this together as a means of exploring Apple's iPhone; I will be comparing it to a Samsung phone with 3 cameras and also to my digital cameras for overall quality and ease of use.  I hope to be finished in about a month or so.

Thanks for reading.

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...

Hang in there, things will get better.

The Svendsen Family - Eric, Samuel, Leanne, Joshua (top row), Nora, Kathryn, Chanelle, Emma If I could go back, in my mind, to a day in my life when I was really down, it would be nice to be able to see into the future.  If could see things as they are today, with the many blessings that have been given to me, it would give me hope knowing that things wouldn't always be so discouraging.   The message here is we do not know what the future holds.  When things are bad, it is hard to raise your head out of the mire to see beyond the darkness.  There are no guarantees, of course, that things will be better, but I think it is true that fortunes ebb and flow as tides do.  The trick is to see beyond the low points and not be too haughty during the high ones.  I know that, at this moment, things are very good.  What the future holds is unknown, but low and high points are likely in the forecast.   This is why taking satisfaction from the moment ...
