As part of the required course knowledge pupils need to be able to outline the process involved in taking a square wooden blank and preparing it for turning between centres. These pictures depict that process chronologically.
Stage 1 * Preparation of wooden blank. Cut to size. Sand square. Mark across diagonals. Centre punch the centre point. Use spring dividers to mark circumference. Repeat on other end.
Stage 2 * Plane off corners down to circumference line. This takes cross section from square to octagon. This reduces force on cutting toll in initial prep of blank. Mount between fork [driven] centre and dead [or live ] centre at tailstock end. Apply grease a dead centre end. apply force from tailstock end to force fork into material at driven end. Adjust toolstock height to suit. Check for clearance.
Stage 3 * Roughout using scraper to diameter. Use combination of gouges and skew chisels to add beads and other decorative detailing as required. Ensure spindle speed is appropriate for material and cross section under consideration. Obey all safety instructions.

Mission Statement of Missouri Botanical Garden: "To discover and share knowledge about plants and their environment." As part of this year's annual holiday light show, strings of lights were suspended over the reflecting pools. I haven't discovered how this light show (and particular the type of installation in the photo) shares knowledge about plants and their environment. I think it sends a very different message about what the Botanical Garden thinks is important and about how they think we should relate to plants in our environment. Saint Louis, Missouri.

I must have been mad but the other guys who missed out wanted to go so I thought what the hell, lets go again and maybe capture something different. So thats what I did today.
A real time capsule but nature is taking back a lot of the rooms with full on decay and collapsed floors. Not to mention a shotgun wielding farmer and a bull roaming the enclosure to make matters worse. No chase today - bull was curiously watching us run away but did not decide to pursue.

隨筆閒聊：關於學藝不精
自幼便認為自己繪畫頗有天賦，讀美術學校時，成積好不在話下。老師教導一定必須先講理論、技法、概念等等，之後才會讓學生動筆，而一定也是基本功必須先練好。每年學校都有一次作品展，有一次主題訂好後，內容可以自由發揮，但老師警告大家，畫什麼都可以就是不可以畫人像，因為我們能力不夠領會奧義，無論你畫得再好一定給0分，偶這成績優異鐵齒白目的小子，自然不把老師講的當一回事，出展後，老師也很給面子，給了我不及格分數，這是我第一次拿到不及格。這是給我一個非常好的啟發，自己丟臉沒關係，但總不能丟老師的臉。那怕是現在我玩攝影已經20幾年，也在業界打混過幾年，初期沒10年我還真不敢拿出來獻寶。直到這1-2年才敢收學生。
現在的人拿手機、傻瓜相機拍照OK普及很好，偶沒啥意見，但很多人拿的單眼才沒幾年搞得好像大師一樣。
前一陣子我遇到一位格西，自己也覺得專研多年佛學，有個問題很難理解，於是請教格西，他說縱使他學佛30餘年也無法保證能解釋的好，這要看問題的目的與方向，我一再央求請他簡單解釋一下即可，格西打死不願說，我想他畢竟不了解我的程度，萬一令我錯解在戒律上可是有過失的。如同先前所述，老師用意是值得尊敬的。
很多學問都是一致的求學過程，現在的人太沒有耐性了，按讚多就以為受肯定，殊不知這會害死自己。我發現越媚俗的東西按讚等比擴大，有深度的則反之，習慣了自然就墮入俗套了。深度的創作都是條孤獨的道路，我跟學生說過，100個外行人對你按讚是一點幫助也沒有，那怕是僅一位高手來對你肯定，那才是勝過千百人莫大的鼓勵。

PS.很多網站都說要你建立良好社交關係(多去吹捧他人)，你的作品才會得到個多讚.......讚你個頭，我不想藐視專業，更不想害死你。我當然會按讚，但起碼我是認真的!!
If school backpacks can transmit as much knowledge to their owners as they seem able to hold to their owners, the 252 girls and boys at Queen’s Nursery and Primary School next to UN House in Juba, some only marginally bigger than their bags, have a bright future.
To promote girl power and progress on the International Day of the Girl Child, female police officers serving with the United Nations Mission in South Sudan visited the school and offered a variety of inspirational activities and revelations.
“Believe it or not, but I was once a small girl just like you! If you look around you, the other uniformed women here have also been children, dreaming of becoming adults. Now we have grown up and become what we wanted to be, by studying hard and following our dreams,” the peacekeeping mission’s Police Commissioner Unaisi Lutu Vuniwaqa confided –even before reaching her main message:
“All of you can become whatever you decide that you want to be. Your future is in your hands, just work hard to make the most of your education,” she added, and stressed that boys and men have an important role to play in supporting and allowing girls to flourish and reach their full potential.
A show of hands, prompted by the Police Commissioner, demonstrated that South Sudanese schools and law enforcement agencies won’t suffer from a lack of future candidates as the pupils of Queen’s School become fully fledged adults.
These preliminary findings were quickly confirmed by 14-year-old Lili John and one year younger Stella Gibson.
“Today is important because going to school gives us knowledge, and I want to become a teacher,” Lili said, still a bit unsure about what subject she would like to teach.
Truck drivers in the country are unlikely to be able to welcome Stella to their fold, but may still get to know her in another capacity.
“A police officer, that’s what I want to be. A strong one,” she added for clarification.
Patience is a necessary virtue for anyone nurturing learning children or putting criminal individuals back on the straight and narrow path of a righteous life. The same will be true for those wishing the mango tree sapling planted on Thursday’s occasion to grow fast to provide the school site with much-needed shade as quickly as possible.
The little fellow, unless it was a girl to mark the day, maybe 20 centimeters tall, was at least given a cheerful start to life, with students, teachers, community leaders and UN police officers willing it on by dancing and singing the infectious and quite possibly recently composed tune “Shake, shake, the mango tree, one for you and one for me.”
Stoical, discerning mango lovers may, however, one day be in luck and see their shares of the spoils grow significantly. Chances are that the little newcomer may soon be accompanied by another 45 tree saplings recently donated to the school by the UN Mission’s environmental engineers. That gift was part of the Carbon Sink Joint Project between UNMISS and the government of South Sudan.

All this info is basic and reflects my current knowledge. I am largely self taught, but flickr has helped immensely. Feel free to point out flaws in what I say. I am by no means an authority on the subject.
I took this before I started to really appreciate what good equipment can achieve. The photo is of a spectacular sunset from my Lincoln Ridge Apartment. The clouds were scattered around the sky in a nice pattern and the light from the setting sun was still visible. I had to capture this picture...and this was the best my SD550 could do. How did I take it and a similar vertical shot?
I used the balcony as a tripod, used vivid colors (to boost the saturation bascially) and the slow synchro mode. Turning up the ISO on these camera typically results in lots of noise (and besides I barely knew what ISO was in August last year).
What is wrong with this picture you ask? Besides the exaggerated saturation, the picture only works in medium size. Try looking at the large or original sizes and the lack of detail becomes apparent. If you want to frame this, forget about it. It is not a good picture, but of course better than no picture...
What would I do today? First, I'd run and get my tripod. Tripods are a must for crisp low light shots, and it works especially well from the no-hassle environment of your balcony. The tripod provides absolute stability for the shot (assuming you don't kick it). That being said make sure to use remote release other the mere act of pressing the button may shake the camera. There are two options to avoid this: (1) use a timer or (2) buy a remote release device that plugs into the camera. Since your camera is firmly attached to the tripod and therefore stable, you can reduce the ISO to 100 and avoid noise/grainy issues (seeing pixels when you see the picture big basically).
Then I'd start playing in the Tv mode and have the camera automatically select an appropriate Aperture. However, the camera frequently selects inadequate aperatures so make a mental note of your Tv setting and move to Manual mode and use this as a starting point. I'd also experiment with cloudy WB and higher saturation. Finally, I'd play with my zoom to frame the picture differently. Not only did my SD550 have poor zoom range, but zoomed picture quickly get blurry without a tripod.
An advanced point and shoot can achieve all this. The only problem with the S3 IS is that it has limits on aperature, and these limitations make low light shoots hard in certain situations. For instance the S3 IS had a limit of f/8 aperature (the amount of light the camera allows into the lense). This is a problem if you want to shoot objects that are very dark or take traffic shots. It is also a problem with flare (since the lights get way to bright). But I'd probably be fine in this shot. So why bother getting a dSLR like my Rebel XTi?
First, the images are much higher quality even if you select the same setting. To see this try looking at one of my night images in original size shot with the S3 IS and the Rebel. Even shots that I consider high quality with the S3 IS do not even come close in detail. Why? The Rebel has a much bigger sensor and much higher quality lenses. This holds for all shots, but it most noticable in difficult light settings.
Second, what if I did not have my tripod? The remedy is then to increase the ISO, however, if you do this on a S3 IS the shot gets extremely grainy (i.e. pixelated). Sure, the S3 IS is a IS camera i.e. image stabilization, but in practice this does not buy you much. In contrast, the Rebel XTi does an excellent job of controlling noise at high ISO so I would simply go to ISO 800 or ISO1600 and try to stabilize against the wall of the balcony. You can also buy IS lenses for the Rebel (which sadly I don't have....to $$$ basically) or lenses with wider aperature (like my f/1.4 lense) - more on that later.
Why is an IS lense useful? Basically you can only handhold a shot at say 50 mm (how much you zoom) at a shutter speed of 1/50. In a low light shot you need to open the shutter long enough to allow enough light in so that your shot is not dark, but you are handholding and if you need to handhold for more than 1/50 you will get a blurry and useless shot (it is just impossible to hold the camera steady for that long). With a IS lense the lense adjusts for the movement and you may be able to get a crisp shot at a much slower shutter speed (which allows more light to enter). People say that you can improve 3-4 steps, that is from 1/50 to 1/20-1/15.
What does high ISO do? It increases the sensitivity of the camera to light and allows you to absorb more light all else constant. The benefit of this is that you can use a faster shutter speed and this increases the likelihood of getting a sharp shot. Examples tend to help so I will give one. Lets say I want to shoot the wall in my room. I put the camera in Av mode (to keep the aperture fixed) and it says 1/13 @ f/2.8 at ISO 100. This lense is 50mm fixed so using the rule of thumb I mentioned above, 1/13 will not result in a crisp shot (you can try using the continuous mode and snapping about 10 and keeping the crispest). An IS lense would help improve the shot, but my lense is (sadly not IS). So I increase the ISO to ISO 400 and down to 1/125 @ f/2.8. Now I can easily get a crisp shot. The downside is more noise; an easy way to notice this is do look at the sky in a night shot. However, with the Rebel graininess is negligible at ISO400.
What does a wider aperture do (lower f/stop)? It allows more light to enter and thereby reduces the time the shutter needs to be open (and increases the chance of getting a crisp shot). In example above I could reduce the f/stop further. For instance, at f/1.4 and ISO 100 I get a shutter speed of 1/50; the higher aperature (annoying aperature and f/stop go in different directions) allows me to avoid increasing the ISO.
The problem is that the basic lense on a Rebel XTi is cheap and is neither IS nor has a particulary low f/stop (3.5 with no zoom). It is easily overwhelmed in low-light shots. However, as you start decreasing the f/stop and move below f/2.2ish your DOF (depth of field - baiscally your lense will focus on some object and blur the background). So whereas my f/1.4 lense helps with low-light (especially indoor shots) to is key to pick the right place to focus (I now fondly refer to this lense as 'el lente loco' :))
So if you want to take high quality night shots or shots in low light get a dSLR like the Rebel XTi. You may be thinking, when do I really need these capability? Think about indoor shots. Often flash fails (and the flash on P&S's like my SD500 is poor in any event) and often it washes out the subtle natural light. Note! Flash would do nothing in the shot above (why? the range of the flash is very limited). Think about the time around dusk and dawn or if its overcast or what about shots inside a store. What if you zoom a lot especially in less than ideal light? There are so many shots I can now take with the Rebel that I could not even dream about with either the SD550 or the S3 IS (which is way better than the SD550) The only downside I see is price and the bulky size. You don't need to know much; just stick it in the auto mode (P is better) and start shooting and then learn by experimeting.
To make a long story longer: consider an example. I've always been a car freak and car photos - especially shot of moving cars - have always fascinated me. One experiment I had recently was taken shot of a moving car at night. This is hard given the low light and the motion of both cars. Increasing the ISO to 1600 (max for the Rebel) and reducing the f-stop to f/1.8 allowed me to get a decent shot at 1/60 (just right for a 50mm lense; I snapped about 4 as the Chysler 300C sped past and one was crisp). Given the high aperture it was also important to manual select the focus point and point it at the car.
There was one problem (and I had figured this out by testing on other cars). The shot was too dark. One solution was to increase the exposure to +1. This increases the demands for light and all else constant reduces the shutter speed (and the chance of getting a crisp shot). Check out the graininess of the shot. The is pretty crisp and sharp, but you can see the noise even in the large size. Try this shot with a point and shoot once....it is illustrative and you will not get close. Even the lense that came would the Rebel would be out of luck.
