What’s Up?

It was a great weekend for all types of football. On Saturday, the Minnesota Vikings came back from a 33-0 deficit in the second half to win 39-36 on a field goal with 3 seconds left in overtime. It was the biggest-ever comeback in an NFL game. In the third game that day, the Buffalo Bills, after trailing by eight points in the fourth quarter, defeated the Miami Dolphins on a 25-yard field goal in a blizzard with no time left on the clock.

The FIFA World Cup final was boring for 82 minutes as Argentina led France 2-0 from early on. France looked as if they were done for until Kylian Mbappé scored on a penalty kick and followed that a minute later with the tying goal. But Argentina’s legendary Lionel Messi poked the ball into the goal to put Argentina ahead again. But not for long as Mbappé netted a hat trick on his second penalty kick. Regular play lasted 90 minutes plus two additional 15-minute periods plus stoppage time. Both teams had numerous great chances for the last fifty minutes; the action was breathtaking. Each team just missed scoring in the last minute of overtime. When that ended, the game was tied at 3-3. Argentina won 4-2 on penalty kicks.

After winning seven Ballon d’Ors, lifting 38 trophies, and playing over 1,000 games in his career, the World Cup was the only title missing from Messi’s resume. It was fitting that the 35-year-old clinched that elusive title in such a remarkable game. Despite not being not quite good enough to inspire France to successive World Cup titles, Mbappé’s third goal secured him the Golden Boot – a trophy given to the tournament’s top scorer. He scored eight goals in Qatar. Read more here. Better yet, see all the thrilling highlights in the YouTube video here.

Today is Monday 19 December. I fly to San Diego for five weeks this morning at 7:15am. I am staying for about five weeks. What can I say? I love the pelicans and the weather.

This image was created on 13 December 2022 down by the Lake near my home at ILE. I used the BLUBB-supported Sony FE 400mm f/2.8 GM OSS lens with the Sony FE 2.0x Teleconverter and The One, the Sony Alpha 1 Mirrorless Digital Camera). The exposure was determined via Zebra technology with ISO on the Thumb Dial. ISO ???. 1/500 sec. at f/5.6 (wide open) in Manual mode. When evaluated in RawDigger, the raw file exposure was determined to be quite excellent — see more below. AWB at 6:58:39am on a cloudy morning about ten minutes before the time of sunrise. Tracking: Flexible Spot/AF-C with Bird Face/Eye detection enabled performed to perfection. Be sure to click on the image to enjoy a high-res version. Crested Caracara — large crop

Image Quality Factors

Many factors determine image quality. Among those are sharpness, clarity, color, and fine detail. The higher the quality of the sensor in your camera and the lens you are using, the better the image quality will be (all else being equal). Understand that cropping always degrades image quality. In addition, and in general, the higher the ISO, the poorer the image quality will be (again, all else being equal).

The JPEG for today’s featured image was created from a TIF file that was cropped dramatically; it represented only 13.5% of the original pixels. 86.5% of the original pixels were cropped away and discarded.

Study the EXIF, enlarge the photo and check out the image quality, put everything together, and leave a comment with your best estimate of the ISO used to create the image.
