I use rechargeable batteries in my bushnell. They last several weeks between charges.

I've been using a Busnell 119716cw for about a year, and while it is fun to see the animals, the picture quality is poor. The model is labeled "16mp", but in reality it has only a 3mp sensor.(you have to read the manual to figure that out) I read one article about trail cameras that said that is true of all of them until you get to the quality used by magazine photographers or scientists who spent $10,000+.
Does anyone have info on outdoor motion/heat detector cameras that have better sensors? Most trail cameras are in the $100-$300 range, but the sensors are not described. There a few that take stills and video at the same time going for about $3000. I don't need to take stills if I could get really good video. I can't find much info on the true quality of cameras sold for security, but prices lead me to guess they are similar quality to trail cams.

I lived in Richland in the late ‘60’s when my husband was a reactor engineer at Handford. Even outside the handford reserve it is an interesting part of the world. Many people don’t realize Washington is half desert and how important the river is for life. Be aware the temperature can vary from -40 to +120. They also have wind and sand storms so bad they can take the paint off your car. During WWII they were called “termination w-inds” because so many people would quit their jobs when one hit.

I use a roll-aboard suitcase. You can add dividers or foam protectors

Not necessarily true. Some teens take very good photographs; just as with any art form some people have an in-born ability. They may benefit from some additional instruction or better equipment. Some of us make do with learning techniques and tricks in an attempt to make up for lack of talent.

I’d reverse it. Let them start with creative side and when they wish the results were better introduce the technical side. People hear the answer better if they ask the question first.

Country cottage or other old buildings.
Farms and hilly pastures
Coast line (Cornwall or Dover)

Depends on where you are looking FROM. They don’t look very old to me. Grey Hair is no longer a sign of old age. More telling is problems with posture, energy level and mobility.
Also, as you get older you get accustomed to the idea of death and get used to visiting cemeteries to either say goodby or to visit Friends.

Since it is by a door, and appears to be about 3-4 inches, I've had luck sticking a hoe out a door to knock it down and then slam the door before the wasps find a way in. Sometimes I need to reach out a second time and smash it with the hoe on the ground.

Ever realized that the word “intoxicated” is based on “toxic”. The feeling is caused by the killing of brain cells. Yes, alcohol is a poison.

Have you tried select by color?

I like 3 best. The contrast between the dark water and the bird combined with the good reflection as well as the pale reeds behind make it eye catching

Since you are doing several pictures, consider how they might be grouped together on a wall, and what size walls he has available. Maybe 4 squares to make a bigger square? Or assorted sizes that highlight different poses to hang over a bed or sofa for a gallery wall? Or will the each be hung in a different room? How they will be hung may influence shape and color/style of frame and mat.
Does he live there full time or is it a second home? An unoccupied Cabin may have higher humility (I know from personal experience). If that is the case consider canvas, acrylic or metal prints as they are less likely to get musty.

I have a D5600 and am very satisfied. I selected it primarily for the articulated screen. I’m 74 and the screen makes it possible to get low angle shots that I would otherwise not be able to get now that I can’t get down on the ground. As far as learning the controls- you can always start with the automatic setting, which is really very dependably good. Then try one new setting at a time. Learning new things is a good way to keep your brain active.

During the ice age there was an ice dam that blocked what is now the Columbia river. From time to time it would break and the resulting flood would scour the area. If you have ever visited the Grand Coulee area you can see rocks the size of houses that were washed down stream by the massive amounts of water. Google Lake Missoula
