Photosynth – An Introduction to Microsoft’s Photosynth – A New Way to Present Your Photos

With Microsoft’s Photosynth those static displays of your holiday photos, for instance, are a thing of the past. Now you can show your friends and family those photos of your trip to The Grand Canyon or The Taj Mahal as a dynamic, moving display!

Your photos will be merged together and presented in an almost cinematic-fashion. It will appear that you are moving around and through the scenery.

The effect is difficult to describe so I would strongly suggest you see for yourself. Once you have seen examples of Synths made by other people and uploaded your photos to make your first Synth I am certain you will be well and truly hooked!

You will be able select any particular photo and zoom in very close and see the tiniest of details. And with modern high-resolution cameras those details can be small indeed!

My very first Synth was made using some photos I already had stored on my PC. They were of my son’s holiday in Egypt taken some time earlier so were not taken especially for Synthing. I picked 6 shots taken at Abu Simbel which were of the same scene and uploaded them to Photosynth. I was staggered by the result. It was almost ethereal! The first photo had my son in the foreground, the next he was with his wife off to one side, then his wife was standing on her own in front of the huge seated figures and then they were back together in the front and so on until the sequence repeated itself. I was amazed as the camera panned and tilted and zoomed in and out.

As I said it is difficult to explain and they do say ‘A picture is worth a thousand words’ so this simple 6 photo Synth must be worth several thousand!

Pause the sequence and individual photos can be selected and zoomed in on to see the tiniest of details. And with modern high-resolution cameras those details can be very tiny indeed!

I have made many Synths since and some of them contain many photos, hundreds in some cases and I am amazed at how beautiful the Synths often are. My cameras are fairly modest but even so the results are impressive. I know that many people use cameras far better than mine and the detail that can be seen in their Synth’ed photos can be staggering.

One of my Synth which I am rather proud of is of St Paul’s Cathedral in London. The photos were taken with my Olympus pocket camera and my Nokia N95 phone so the pictures are not the most detailed and probably don’t stand up to too much zooming but the overall effect is very impressive as the camera swoops around the Cathedral and nearby buildings. Buses come into picture then fade away, people appear and then disappear and all the while the camera is moving around the building and spinning around corners, looking up and down. Search for ‘St Paul’s Cathedral 291008′. I was very pleasantly surprised that it had been marked as a Featured Synth so I must have done a reasonable job on that one!

Attaining 100% Synth can be a little tricky at times but well worth the effort. Use photos that have a good area of overlap. This will help to ensure that Photosynth finds plenty of matching points and also use bright, clear, sharp images. If you have any photo editing software use that to brighten and sharpen up any dark or not quite in focus photos. It could be that not quite perfect photo is the one that links 2 sets of photos together to give that 100% Synthy rating.

Photosynth can be easily found by just searching for it by name in Yahoo or Google. And don’t forget it is free, so do have a look!

I can thoroughly recommend Photosynth and I am sure you will love it once you’ve tried it for yourself.

Why is Chlorine Present in Drinking Water?

Why should chlorine be present in our drinking water? It is for very good reasons, as the treatment and distribution of safe drinking water are considered by the U.S. Centers for Disease Control (CDC) as one of the major public health achievements of the twentieth century.

Towards the end of the nineteenth century it was found in London, UK, that water from a city well that had spread infectious diseases ceased to be dangerous after having been treated with chlorine.

Then in a few years the practice of water treatment was adopted by most of the civilized world as a means of protecting public health.

Up to those times drinking wine instead of water of dubious quality was the best assurance against illness, for those who could afford the expense.

Disinfecting the drinking water for human and animal use ensures that it becomes free of active microorganisms causing serious and life-threatening diseases, such as cholera and typhoid fever.

Chlorine is effective in killing most pathogenic bacteria and viruses. Chlorine however is not effective in killing certain protozoa like cryptosporidium.

The term chlorine refers to the chemical element Cl that exists as a poisonous yellow gas, irritant of the respiratory tract even at low concentration. As it is a very active element it is found in nature mostly as a compound, of which common table salt, sodium chloride (NaCl) is an example.

Chlorine gas is soluble in water. A common household product, bleach, is a water solution containing about 3 to 6% of sodium hypochlorite (NaOCl). This product too can be used to disinfect water in case of need.

Additional chlorination effects are the removal of iron and manganese and the residual property of continuing to hinder pathogen reproduction during the long way from the treatment facility to the house tap.

Is it safe to human health to drink chlorinated water?
It depends on whom you ask.

Some studies point to increased risk on health, while others show no additional risk.

It is generally recognized that drinking water chlorination is the process of choice for eliminating most of the life-threatening pathogens possibly present in the water reaching treating plants.

Some research efforts concentrating on the effects of certain by-products of the treatment, seem to suggest that substances like Trihalo-methanes (THM) have the potential to induce cancer in individuals as they do in laboratory animals when supplied at very high levels.

However it is commonly accepted that their presence in treated water in minimal quantities is far from threatening.

EPA regulates how much of these substances are tolerated in chlorinated water for safe use. The current EPA regulations establish a limit of 80 parts per billion (ppb), for THMs based on the annual average of eight distribution system monitoring locations.

Industrial and commercial sources, with deep interests in the use of chlorine and its derivatives, vehemently insist that independent medical sources failed to find statistically relevant results connecting chlorine with development of cancer diseases.

Other sources interpreting more strictly the results of certain research, seem to find concrete demonstration of the dangerous effects on health of chlorinated water.

Until more definitive research will authorize to settle the dispute by defining ways to sort the probable outcome of illness course according to additional contributing factors, it is possibly quite safe to assume that the present official standing of appointed authorities on water quality should be accepted except perhaps in unusual circumstances.

All sources agree that the benefits of chlorination for eliminating the presence of pathogens, are much greater than the minimal risk still remaining, if at all, relative to residual by-products.

The other existing means for obtaining a comparably safe result (ozonation, Ultraviolet light treatment, and use of chlorine compounds like chloramines and chlorine dioxide) are more expensive and do not provide sufficient advantages to promote their substitution.

It is suggested by professional experts that installing a suitable home filter at the point of use removes the nuisance of chlorine and byproducts from the drinking water.
