Back to photography: Here are some guidelines and basic rules about composing your photographs. Nothing spectacular, but a good basic introduction worth reading.
I am spending quite a lot of my time travelling through the global net. Amogst a lot of rubish I there are a lot of very good/interesting/informative/funny sites and my bookmarks are growing by the day. Here are some of my best finds.
Today's Link of the Day comes straight from the FM4 Webtip: A long, in-depth and honest analysis of the last four years of Americas "War against Terror" published by the New York Times. It is a long read, but - in my opinion - worth the effort and brings some intresting new insights.
If you do not have a NYT-account and do not want to register (for free), you might want to use bugmenot.
For better reading experience, I'd recommend copy&pasting the printer-frindly version to a text processing software of your choice, formatting in tree colums (with justified text) and printing it. I used AbiWord to further export it to LaTeX (cool feature by the way) and letting the TeX engine do the typesetting.
The Wikipedia works, wikis are sprouting everywhere, so why not have a wiki with travel information? Wikitravel is collaborative effort to collect unseful information and tips about as many destinations as possible. And it seems to work. At least the info about Austria is far more accurate than the one in some other guides I have seen. (The drawback is that I these other "guides" were by far funnier)
Even when it does not give you in-depth information, Wikitravel is a good starting point when planing a stay in a foreign country.
Todays "Link of the Day" is about the old competition of naming the biggest number one can imagine:
You have fifteen seconds. Using standard math notation, English words, or both, name a single whole number—not an infinity—on a blank index card. Be precise enough for any reasonable modern mathematician to determine exactly what number you’ve named, by consulting only your card and, if necessary, the published literature.
The follwing discussion starts by gowing from Addition to Multiplication to Exponentiation etc. Then in introduces the concept of Turing machines and computability. Finally it show that there are non-computable functions which grow even faster.
This page should be readable and enjoyable for mathematicias nad non-mathematicians alike.
I am spending quite a lot of my time travelling through the global net. Amogst a lot of rubish I there are a lot of very good/interesting/informative/funny sites and my bookmarks are growing by the day. So I thought I might as well share them with you. This is planned to be a more or less daily feature. To get only the Links of the Day, go to the category listing or subscribe to the RSS feed.
I am starting this series with an excellent article by ArsTechnica: Editing your digital images without the mystery. This article/tutorial covers the basics of enhancing digital photos:
We'll cover a number of goals like adjusting contrast, warming imagesup and reducing noise from shadows in a more accurate and controlledway. Then we'll get into advanced stuff like masking but all explainedin an almost-too friendly, "why are you touching my arm?" sort of way.
The article does not cover photo manipulation, but only the stuff most good digital photographers do with most of their images.
