Prince Regent Royal Pavilion
Part of a set photographs of the Prince Regent’s Royal Pavilion (also known as Brighton Pavilion).

Built in the Indo-Saracenic style, borrowing ideas from Indian architecture in the days when that region was still part of the British Empire.

Unlike the originals, the building’s frame is Cast Iron – cutting edge technology at the time when the building was redeveloped by the architect en.wikipedia.org/wiki/John_Nash_(architect) are actually very small scale – much too small for an adult to fit inside. Like the shrunken higher up windows and tapering outline of the Senate House of London University, the reduction in size of the minarets adds to the illusion of scale.

The viewpoint (often used in picture postcards) is also deceptive. By perching the camera on the edge of a small (four paces by ten paces) ornamental pond, the false impression is created that the pavilion is adjacent to a huge lake.

There is an official Royal Pavilion website.

During Work War II, Adolf Hitler is famously claimed to have spared the Pavilion from bombing because he wanted to use it has his English headquarters. This is reputed to be based on statements by William Joyce, an American born German radio propaganda broadcaster (named Lord Haw-Haw by British listeners), statements presumably made to demoralise listeners into the belief that this outcome was inevitable. Brighton was bombed, however, so maybe the Luftwaffe just missed.

The image is made up from High Dynamic Range (HDR) files. A large number of (identically framed) bracketed exposures were merged into a single HDR file. This 32 bits per channel file (over 4 billion shades of red, green or blue) was converted to a more mundane 8 bits per channel jpeg file. (It is not currently technically feasible to fully display 4 billlion shades per colour on a computer monitor, or on a print.) In the conversion process Local Adaptation was used, a trick that enables the detail in both very bright (floodlit) areas and very dark (moonlit) areas to be viewed in the same image. The human visual system is particularly sensitive to detecting edges, and "overlooks" intervening smooth gradients. This makes Local Adaptation a viable technique / optical illusion.

The image has also been modified using transformations to remove any barrel distortion, and also adapted to ensure a classical perspective with parallel verticals.

A Canon 300D DSLR was used. The number of exposures ranged from 1/250 sec. to 30 secs. in 2 EV/stop increments. Two large, nervous, ornamental carp live in the pool. I think that they moved about between exposures, causing the feint, strange, multiple streaks in the surface of the pond.

    Very Impressive Product – Bought Four More!, October 2, 2011

    By K. J. Simon (The Great Lakes State) –

    Verified Purchase(What’s this?)

    This review is from: 3M Privacy Filter for 19″ Standard Monitor (5:4) (PF190C4B) (Personal Computers)

    My work space is like a fish bowl. I often work with student or applicant confidential information on my computer. I always felt guilty whenever someone approached me and I hit Alt-Tab to switch to a benign screen – I worried that it suggested inappropriate use of my computer rather than work 🙂 !

    I’m using the 3M Privacy Filer PF 19 on a Dell LCD 19″ monitor.

    Things to Consider When You Purchase a Privacy Screen:

    PRICE: I got out the catalog of the office supply chain that offers our institution a discount and checked the prices of privacy screens. Then I talked to our IT department and found out what they could offer my department. To say I had sticker shock is an understatement! One source was $100 more, our own IT department was $30 more than the screen I’m reviewing here and purchased from Amazon.

    STYLE: I checked different privacy screens throughout our 8 story building and decided that there was no clear advantage to having a frame around the screen. It added to the bulk and quite a bit to the cost. The screens I looked at without frames were held in place by small tabs that came with the screen and attached to the monitor frame. No one I spoke to who used the frameless models reported any problems with the screen falling out, and a number of users said it stayed in place without the tabs (as I discovered later, mine does too).

    EFFECTIVENESS: This privacy screen works very, very well. I’ve lost track of how many people have made me laugh by stopping and watching me stare at my screen as I’m intently reading something and asking me what’s so fascinating about a monitor that’s not on! I usually laugh, switch to a neutral web page and invite them over to “see” what I can see. The next question, after the “WOW”, is where did I get it? I’m glad I kept the original packaging because I just pull it out and lend it to the person and usually I hear later that they’ve ordered one for their workstation(s).

    As another reviewer noted, unless someone is standing right behind you or within approximately 20 degrees of the center of your monitor, they won’t be able to see what’s on your screen. And yes, if someone walks behind you, there is a point in their pass-by that they can see your screen, but it’s brief, and unless they stop to focus, they quickly are out of the “I can see your screen” zone.

    NICE FEATURES: There are two different “finishes”, or looks to the screen. One side is a high gloss, the other matte. After using it both ways, I’ve decided that the gloss works better for my eyes. A second nice feature is a little half-circle, thumb-notch in the screen, at the top, that makes it easy and fast to pull the screen off the monitor if you want to share your screen with those around you. When I’m done sharing, I just pop it back into place. This is easy because as I mentioned before, the privacy screen stays in place wonderfully without the need for the tabs that are included.

    The 3M Privacy Filter -3M PF19 is a product that not only would I purchase again, but did – 4 more of them for just our little department. I’ve always trusted 3M products, and this item has reinforced that trust.

    Could have been great if it weren’t for the awful glue strips, January 8, 2018

    By razzman_d (O-H!) –

    Verified Purchase(What’s this?)

    This review is from: 3M Privacy Filter for 23.6″ Diagonal Standard Monitor, Protects your confidential information, Reduces reflections and blue light (PF236W9B) (Personal Computers)

    They work exactly as advertised on the privacy side, but for attaching to the monitor they are pretty bad, and if they won’t stay put then what’s the point? I am using the tacky strips, and the screen will not stay stuck to them. I put them on last week, and after this weekend I walked into my office to find them laying flat on my desk. Now I am finding myself constantly pressing them against the strips so they’ll stay in place.

    I can’t use the clips as that causes them to bow and bend and create out of focus areas.

    For the price this is a terrible result.

    HIGHLY Recommend THIS item, September 30, 2012

    By Safiya Ahmed Mohammed (Abu Dhabi, United Arab Emirates) –

    Verified Purchase(What’s this?)

    This review is from: 3M Privacy Filter for 22″ Widescreen Monitor (16:10) (PF220W1B) (Personal Computers)

    I used this on an HP Compaq LA2205wg screen and it fit PERFECTLY. There are 2 sides to this filter (which doesn’t stick on the actual screen), one glossy and one matte. I used the matte side to face me, and from a distance the screen looks completely black. At closer proximity to the computer monitor, things are visible and if someone’s standing directly behind, the screen is clearly visible. However, it has immensely increased the level of privacy and I can work happily knowing that no one’s watching me from behind. The filter can be lifted for cleaning and the see through stickers that you attach to the screen are to help keep it put. Even without the stickers, the filter will stay put.

    Buy it, it’s totally worth it, although HIGHLY priced.
