You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 44.195.0.0/16 has been blocked (disabled) by ‪Blablubbs‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 09:46, 11 January 2025.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

'''John Nash Ott'''<!--not "Dr."...Ott did not have a degree, having never gone to college--> (23 October 1909 – 6 April 2000<ref name="obit2000"/>) was a photo-researcher, writer, photographer, and cinematographer who was an early adopter of many modern photographic practices, including time-lapse photography and [[full-spectrum light]]ing.((citation needed|date=July 2018))

==Photography==
Ott's early career was in finance. He never went to college,<ref>((Citation|title=Dr. John Ott: The Light Side of Health|url=https://www.motherearthnews.com/nature-and-environment/john-ott-zm0z86zhun))</ref> although he enrolled in finance courses at Harvard Business School while working for several Chicago area banks. During this period, he developed an interest in [[time-lapse photography]]. He made his first time-lapse film in 1927, while he was still in high-school,<ref name=":0">((Cite book|title=My Ivory Cellar|last=Ott|first=John|publisher=Twentieth Century Press|year=1958|lccn=58-59587|location=Chicago, IL|pages=122))</ref> but did not develop the automated mechanical camera rig which he used in his later films, until 1937. His early amateur films led him to a career in [[cinematography]]. In addition to making films, he performed research about the effects of natural lighting on plants, animals, and humans.

Initially, Ott's interest in time-lapse movie photography, mostly of plants, was just a [[hobby]]. Starting in the 1930s, Ott bought and built more and more time-lapse equipment, eventually building a large [[greenhouse]] full of plants, cameras, and self-built automated electric moving camera systems (the first movie camera [[motion control]] systems ever built) for moving the cameras to follow the growth of plants as they developed. He time-lapsed his entire [[greenhouse]] of plants and cameras as they all worked and grew.

His work caught the attention of organizations who employed him to make time-lapse segments for films they were producing, including the educational film ''Secrets of Life'', for the [[The Walt Disney Company|Walt Disney Company]] in 1956,<ref name=":0" /> and ''The Story of Wheat'', for the [[Atchison, Topeka and Santa Fe Railway|Santa Fe Railroad]].<ref name=":0" /> From the late-1940s to the early-1950s he hosted a Chicago-area television program called ''How Does Your Garden Grow'', which featured gardening tips, botanical information, and short time-lapse films. Episodes of this program can be viewed on the YouTube page of the [[Winnetka, Illinois|Winnetka]] Historical Society.<ref>((Citation|title=Dr. Tilden Roberts on HDYGG, John Nash Ott ((!)) Winnetka Historical Society|url=https://www.youtube.com/watch?v=cv1bPbv_tpM|language=en|access-date=2019-08-13))</ref> More episodes of ''How Does Your Garden Grow,'' Ott's educational films, and raw time-lapse footage can be viewed from the [[Chicago Film Archives]]' John Nash Ott Collection.<ref>((Citation|title=John Nash Ott Collection ((!)) Chicago Film Archives|url=https://collections.chicagofilmarchives.org/Detail/collections/117|language=en|access-date=2023-11-16))</ref>

Ott developed a theory in the later years of his life that movement of plants could be manipulated by varying the amount of water that plants were given, and varying the [[color temperature]] of the lights in the studio, with some colors causing the plants to flower and other colors causing the plants to bear fruit. His 1958 memoir ''My Ivory Cellar'' details not only his personal history as a filmmaker, but also outlines these ideas.

Ott's experiments with different colored lighting systems and their effects on the [[health]] of plants led to [[experiment]]s with colored lights on the health of animals, humans, and individual cells, using time-lapse micro-photography. Ott's experiments led him to believe that only a [[full-spectrum light|full spectrum]] of natural light (including natural amounts of [[infrared]] and [[ultraviolet]]) could promote full health in plants, animals, and humans. He wrote a 1973 book entitled ''Health and Light'' advancing his theories. Such topics were also addressed in his 1974 film ''Exploring the Spectrum.''

Ott received an honorary doctorate in science from [[Loyola University of Chicago]] in 1958.<ref>((Citation|title=Honorary Degree List|url=https://www.luc.edu/honorarydegreelist/))</ref> Although it is not customary for recipients of such an honorary doctorate to adopt the prefix "Dr.", he was widely referred to as "Dr. Ott" thereafter.

==Natural lighting products==
Ott believed that the proprietary [[lighting]] technology he developed was the closest replication to the sun's natural wavelengths. He developed several consumer products based on this technology, including altered lightbulbs and a special pair of polarized sunglasses which he believed would enhance the physical and mental fortitude of anyone wearing them.<ref>((Citation|title=Ott Sunglasses Infomercial ((!)) John Nash Ott|url=https://www.youtube.com/watch?v=ZbF9-q3Rc3c|language=en|access-date=2019-08-13))</ref>

In 1989, entrepreneur Fred Mendelsohn started Environmental Lighting Technologies (doing business as Ott-lite Technologies) and worked with Ott to develop the technology into award-winning products for businesses and homes. OttLite describes its "508 technology" as providing a balance of brightness and contrast that reduces glare and eyestrain and produces very low heat. The products, called "High Definition Natural Lighting", are marketed online and at lighting, crafting, and hardware stores.
