What Is Depth of Field in Cameras ?

The depth of the image which can remain in acceptably sharp focus with any given lens and given aperture. With telephoto lenses this is very narrow, with macro lenses narrower still. Wide angle lenses can keep nearly all of an image sharp. The Hyperfocal Distance (best chance of keeping everything in focus) is about 1/3rd of the way into the image.

Opinions On A Few Of My Photos Please? Thanks!?

I think the duck is really good - and the little boy looking out of the window emotes a great deal of depth and feeling. The candles do not seem to have proper lighting or composition. Keep pursuing what you love!

Depth chart position

Compared to other American football positions, the holder is one of the most trivial positions, requiring precision in the receipt of a snap and placement of a ball in short time, but requiring far less physical talent than a skill position and much less bulk or strength than a lineman. Because of this, it is exceptionally rare for a team to preserve a roster spot solely for a placekick holder; most teams will instead use a player who plays another position to double as the holder. One notable exception was Patricia Palinkas, the first female professional football player; Palinkas played holder (and no other position) during her short time as a pro player. The holder's actual position, on the team's official depth chart, is generally either the punter or the backup quarterback. Some high school football teams will place a wide receiver or running back at the holder position because of their good hands (this is not unheard of at other levels; Steve Tasker, a wide receiver and punt gunner, also played holder at various times in his NFL career, as does his son Luke Tasker, also a wide receiver. Others include tight end Jay Novacek safeties Paul Krause and Keith Lyle). Backup quarterbackThe rationale for having a backup quarterback holding is that the quarterback is accustomed to receiving snaps from center and long snaps from the shotgun formation. He also provides a threat for a fake field goal since the quarterback can throw a pass on such plays. Additionally, in the event of a bad snap and an aborted kick attempt, the holder might have to become the quarterback for the play, so having an actual quarterback helps in that regard. Years ago in the NFL, backup quarterbacks generally held for field goal kicks. Having the backup quarterback play as the holder has faded out in the NFL, mainly due to a rule in the NFL's collective bargaining agreement that prohibited a team's third-string quarterback from playing except in emergencies (this was repealed in the 2011 CBA, but since that time, most NFL teams have only carried two quarterbacks on the active roster). However, such usage has remained rather common in collegiate football. Many times a quarterback who was a redshirt freshman will serve as the holder his sophomore year. It is also common in other professional leagues such as the Arena Football League (where there is no punting and are thus no punters) or the Canadian Football League, where roster size restrictions generally result in one person serving as both placekicker and punter. PunterIn today's NFL, most teams use their punter as holder. New England Patriots' head coach Bill Belichick explained that punters are generally holders for the reason that punters and kickers usually have more time together to game plan, watch film, and are able to have more reps during practice than a player who has to play another position. ExceptionsThere are a few NFL teams that still use a quarterback as their holders. New Orleans Saints - The Saints tend to run more fake field goals than any other team, and due to that they generally keep a backup in as their holder (this keeps opposing defenses in more of a zone coverage, and also helps to prevent blocked field goals). Their holder for a period was quarterback Luke McCown, but is now punter Thomas Morstead. In 1970, Saints kicker Tom Dempsey kicked a 63-yard field goal, which for many years thereafter was the all-time record. Dempsey's holder was a defensive back named Joe Scarpati. There has been an urban myth going around during the intervening decades that the holder on this legendary kick was the team's colorful starting quarterback, Billy Kilmer, who did hold on occasion. Dallas Cowboys - When Tony Romo was signed by the Dallas Cowboys, he was their backup quarterback, and as the backup quarterback, part of his job was to be the team's holder. Romo was replaced by the punter in 2010, but due to many mishandled snaps, which resulted in missed field goals, Romo returned as the team's official holder. The Cowboys hired a more experienced holder, Brian Moorman, in 2012; Moorman left the team at the end of the season. Throughout the 1990s, starting tight end Jay Novacek was the usual holder on kicks. Oakland Raiders - The Raiders' Matt Schaub was used as the holder during the 2014 season. Previously, Daryle Lamonica (1967-69) and Ken Stabler (1970-75) held for George Blanda; when Blanda retired in 1976, the holding duties were assumed by punter Ray Guy, who continued to do so through his retirement following the 1986 season. Denver Broncos - The Broncos used to have former starting quarterback Jake Plummer as the holder and continued to do so after he was benched in favor of Jay Cutler. After Plummer retired the Broncos began to use their punter as the holder. Washington Redskins - Starting quarterback Joe Theismann held for Mark Moseley from the late 1970s until he suffered his career-ending broken leg during a 1985 Monday Night Football game vs. the New York Giants. Seattle Seahawks - Steve Largent, a wide receiver, was the kick holder, and in 1985, he ran in a muffed snap for an extra point.

That depends on what you want to do. When it comes to the actual VR hardware, I would have to assume no. But many companies are getting creative with their VR products. I'm answering from my phone so finding links is too much of a pain in the ass, but there are compabies releasing VR gloves, special 360-degree "treadmills" so you can run in VR, a special VR chair that lets you use your feet to move in VR and swivels, and even an excercise bike designed for VR. When it comes to software development, you could potentially compete. Unity and other platforms have begun releasing tools for VR software developers, so it should be relatively cheap and easy for you to get started.
