My L01 handphone selfie stick and tripod with Bluetooth shutter button

You might have awared that I am using Iruin to make use of my handphone camera as computer webcam.

This solution works pretty well. However, I found that I need a mini tripod to hold my handphone to get a better camera shooting angle, and I have found this L01 selfie stick which can also act as a tripod stand. Its price of below RM20 is very affordable.

The length of this L01 selfie stick, when folded, is only about 18.6 cm, which is very handy to carry along. It has a pretty light weight of 155 gram. It comes with a nice pouch too.

To use it as a tripod, just hold your handphone with its clamp, and unfold its 3 retractable legs.

The clamp is flexible to hold handphone of width between 5.5cm to 8.5cm, including the thickness of protective casing, if there is any.

Its length can be extended up to 70cm, by pulling out its stainless steel pole.

Obviously, you can use it as a selfie stick as well, by folding its 3 legs.

Its handphone holder is 360 degree rotatable, so you can take photo and video in portrait mode as well. 

The holder can be tilted up to 200 degree, to adjust the camera shooting angle.

This selfie stick has a handy Bluetooth shutter button, which is detachable.

The shutter button is powered by a CR1632 battery inside it, which is changeable.

To pair this Bluetooth shutter button with your handphone, just long-press it, and confirm the Bluetooth pairing in your handphone.

After pairing, you can use this button to take photo with your handphone.

The button will automatically disconnect and shutdown itself after 600 seconds of non-operation.

This L01 selfie stick is multi-functional, very easy to use, and made with pretty solid material. I like it very much.

The real fact about your Lithium-ion battery life and death

Nowadays, Lithium-ion battery is commonly used to power up electronic gadgets including laptop, netbook, tablet PC, mobile phone, cordless phone, digital camera, GPS navigator, PDA, MP3 player, etc.

There are quite a lot of information in the Internet teaching you how to prolong the lifespan of your Lithium-ion battery, but not all of them are true. Some are even misleading and ridiculous.

The information below is summarized from 2 websites, namely:

1. batteryuniversity.com
2. howstuffworks.com

which I believe to be more reliable source to learn about the real fact of your Lithium-ion battery life and death.

Here we go:

• Lithium-ion batteries age. They start degrading as soon as they leave the factory. They will only last 2-3 years from the date of manufacture whether you use them or not. You should fully make use of your Lithium-ion battery, because it will still die off even if you store it aside and not using it for long time.
• Lithium-ion batteries are good in holding charge. A lithium-ion battery pack loses only about 5% of its charge per month when not in use. (Compared to 20% loss per month for NiMH batteries)
• Lithium-ion batteries have no memory effect. You don't have to completely discharge them before recharging.
• If you completely discharge a lithium-ion battery, you can no longer recharge it. It is ruined. However, the battery has electronic mechanism to prevent it from complete discharge by stop working when the voltage is too low. A fully discharged battery left for a long period of time will lose its charging capacity.
• Lithium-ion batteries can handle hundreds of charge/discharge cycles. Don't worry about recharging it often.
• Lithium ion chemistry prefers partial discharge to deep discharge. Your battery can have longer life if you charge it often rather than charging it after deep discharge.
• Lithium-ion batteries can have as much as 4,700 discharge cycles if you recharge it at every 10% drop in capacity; 2,500 discharge cycles if you wait until 25% drop; 1,500 discharge cycles if you wait until 50% drop; and only 500 discharge cycles for 100% full recharge.
• Avoid leaving them in high temperature, such as in a car parked at sunny outdoor. Heat causes lithium-ion batteries to degrade much faster than they normally would. Keep your battery below 30°C (86°F). Extremely high temperature might also cause battery explosion.
• When stored in 0°C, Lithium-ion batteries suffer about 6% permanent capacity loss in 1 year. At 25°C, they suffer about 20% permanent capacity loss in 1 year. At 40°C, they suffer about 35% permanent capacity loss in 1 year. At 60°C, they suffer about 40% permanent capacity loss in 3 months.
• Normally, there is built-in mechanism to prevent Lithium-ion batteries from overcharging, so you don't have to worry about battery degrade due to overcharging. However, if such mechanism failed, overcharging might cause excessive heat generated, which is harmful to the battery's lifespan.
• Most lithium-ion batteries cannot exceed 4.20V/cell. While a higher voltage would boost up the battery's capacity, over-voltage shortens its life.
• High charge levels and elevated temperatures hasten permanent battery capacity loss. This is the reason why some people prefers to remove the battery from laptop when it is on A/C power (so that the battery will not be always fully charged, and expose to the heat generated by the laptop). 
• Storing the battery at 40%-60% state-of-charge instead of fully charged can prolong its life.
• Avoid ultra-fast charging and discharging. If the charger allows, lower the charge voltage limit to prolong battery life. In this case, sometimes charging the electronic gadget by connecting it to a computer's USB port is more preferable than charging it with wall socket charger.

Cleaning camera lens with LensPen miniPro II

How do you normally clean the dirt, dust, grease, fingerprint, etc. on the camera lens of your digital camera and/or handphone? Using special cleaning fluid? Using brush? Wiping with microfibre? Wiping with cloth? Wiping with tissue paper? Wiping with your shirt? Never clean and let it be?

Regardless how you do the cleaning, I believe the bottom line is:

• The glass surface, as well as other parts of the device, won't be hurt or scratched
• The cleaning must be effective

I use a Canadian product called LensPen miniPro II to clean the camera lens of my digital camera as well as my handphone. It is very effective and inexpensive (selling at RM23 only).

LensPen miniPro II contains 2 cleaning parts. At one end, there is a retractable ultra fine brush to brush away dust and other particles deposited on the lens. At the other end, it has a special cleaning tip to wipe the lens. It is claimed that this special tip can do more than 500 times cleaning.

LensPen miniPro II has a compact size, easy to carry around or put in the camera bag. Its cleaning tip is small enough to be used for compact digital camera and the handphone camera lens. There are also LensPen products with larger cleaning tip for bigger DSLR lens. There is also LensPen MicroPro to clean even smaller lens surface.

To let you have a better picture of its length and size, here is my LensPen miniPro II putting together with my Canon PowerShot S95 digital camera.

Luminance histogram and RGB histograms in digital camera

One of the nice features in digital camera that cannot be found in traditional camera is the ability to display histogram.

Histogram shows the distribution of brightness in an image horizontally, and the amount of brightness vertically. A typical histogram looks like mountain as below. It is a handy tool to evaluate the exposure.

If you see the peaks are gathered on the left, the image is dark; and if you see the peaks are gathered on the right, the image is bright.

In normal situation, we would like the peaks to be in the middle, so that there is no under-exposure (too dark) or over-exposure (too bright). However, there are situations when dark is OK (e.g. shooting the Earth Hour scene) and there are situations when bright is OK too. Anyhow, you can make use of histogram to assist you in adjusting the exposure value of your picture.

Canon PowerShot S95 camera is able to show histogram in Shooting Modes and Playbank Modes. Histogram is not available in Auto modes (you won't need it, as the camera is taking care of the exposure adjustment for you), and is available for P, Tv, Av, M modes.

Canon PowerShot S95 has two customizable shooting displays, and the default setting for each of the shooting modes is different. You can use the Custom Display setting to turn histogram on or off for either one or both of the shooting displays. You can switch between the custom displays using the DISP. button.

Histogram can also be shown in Playback screen of Canon PowerShot S95. You need to switch to the Detailed Information Display playback screen in order to see the histogram of the picture. You can rotate among the available playback screens by pressing the DISP. button. You can set the default playback mode with the Review Info option.
Canon PowerShot S95 is able to display the RGB histograms of the picture in Detailed Information Display screen. You can toggle RGB histograms on and off by pressing the "Up" button when you are in Detailed Information Display.

The RGB histograms show individual graph for each of the Red, Green and Blue colour captured by the camera in the picture. This will be good piece of information to judge the colour and white balance of the picture.

Shooting modes of Canon PowerShot S95 - from fully automatic to fully manual (part 2 of 2)

In the 1st part of this article, I wrote about the shooting modes of Canon PowerShot S95 digital camera when you dial its mode dial clockwise from Auto (inclusive). Now I would like to share about what I learnt about the shooting modes of this camera when you dial anticlockwise from Auto.

P-mode (Program mode)

P-mode is very close to Auto mode as opposed to Manual mode, in the sense that the camera will automatically adjust the aperture and shutter speed for you. One of the major reason for using P-mode (and above) is the ability to save the picture in RAW format for post processing.

In P-mode, you can decide on the image brightness/darkness by controling the ISO level. You can also make correction to the white balance.

Normally, we like to keep the ISO level as low as possible to produce better quality photographs. That's why we want to take control over ISO level adjustment rather than using Auto-ISO.

ISO level controls the light sensitivity of the camera's image sensor. If the ISO level is too low, you might get camera shake (blur) in the photos. If the ISO level is too high, you will get a lot of digital noise (grains).

Canon PowerShot S95 supports ISO levels from 80 until 3200.

P-mode is handy when quick adjustment is needed to shoot the precious moment that won't wait.


TV-mode (Time Value, Shutter Priority mode)

TV-mode allows us to control the shutter speed, which determine how long the camera's image sensor is exposed to light.

You can use longer shutter speed to capture trailing motion effect, and shorter shutter speed to freeze the moving objects.

Canon PowerShot S95 supports shutter speed as fast as 1/1600 second and as slow as 15 seconds. You need TV-mode to set for slower shutter speed less than 1 second.


AV-mode (Apperture Value, Apperture Prioirty mode)

The aperture controls the depth of field of the photo.

Wider aperture enable you to produce photos of shallower depth of field, with clear focus object and blur out its background. Smaller aperture creates deeper image, with more sharpness across the whole picture.

AV-mode is best when shooting macro (close up) photography with wide aperture. It is also suitable to shoot for landscapes and sceneries with small aperture.

Canon PowerShot S95 supports apperture value from f/2.0 to f/8.0. The smaller the f-number, the larger will be the aperture. One of the selling point of S95 is its f/2.0 capability.


M-mode (Manual mode)

This is the fully manual mode for the professionals. In Manual mode, you take full control to adjust the aperture (rotate the front dial) and shutter speed (rotate the control dial). You can also decide on the ISO level.

As opposed to the P-Mode, the exposure reading is displayed on the LCD screen, and change accordingly when you adjust your aperture and shutter speed.


C-mode (Custom mode)

This is a place for you to instantly get back your favourite settings. You can make the adjustments and settings to the camera, then save them by using the "Save Settings" menu options. When you come to C-mode, you'll get back the settings and adjustments.

Shooting modes of Canon PowerShot S95 - from fully automatic to fully manual (part 1 of 2)

Canon PowerShot S95 is my first high end digital camera. Before this, I use a Kodak EasyShare LS743 point-and-shoot digital camera which doesn't have so much features (it is my 1st digital camera purchased in 2004 and is 7 years old now).

So, what I'm going to write down here is something new I just learnt in order to know how to use my PowerShot S95. If you are also a rookie photographer like me, probably this information might be useful to you too.

You can find the Canon PowerShot S95 camera's shooting mode dial on its top right. This is the dial to control among fully automatic, semi-automatic, and fully manual modes of photographing. It is also the place to switch between photographing and video-graphing.

AUTO mode

This is the fully automatic point-and-shoot mode to let the camera decide and adjust itself on almost everything to get a good quality picture (in the camera's A.I. points of view), and you cannot take control most of the settings in this mode. In Auto mode, your main concern is the focus (or focuses) of the image. Canon PowerShot S95 supports 9-point face detection AiAF, and also 1-point AF at the center.

This is a good mode to start with, before you familiar with the camera features and functions. You can straightaway start shooting photos with this mode right after you get it, even without reading its manual or knowing its controls and settings.

It seems that you can only save the photo in JPEG and cannot save it in RAW mode. Photo saved in RAW mode allows you to do post processing using Canon Digital Photo Professional software provided in the CD that bundled in the box with the camera.

Photo saved in JPEG image is 8-bit image and RAW mode is 14-bit image. This means more colour information is saved in RAW mode.

Low light (Candle) mode

This is a point-and-shoot mode used to take photos in dim environment. The camera will automatically use a wider aperture and higher ISO level for the picture. (Normally, we should use ISO level as low as possible to reduce noise in the picture)

It is ideal to capture dark situations, especially when you don't want to use the flash light. Example will be birthday cake with lighted candles in a dark indoor.

Scene (SCN) mode

This is a point-and-shoot mode to tell the camera to optimize itself specific to the subject you want to shoot. Sometimes, the camera Auto mode has no idea what type of subject you are photographing, and you can get better pictures using SCN mode instead of Auto.

The modes available for Canon PowerShot S95 are: portrait (shooting people), landscape (shooting scenery), kids & pets (capture the moment while they are moving around), beach (people in bright surrounding), underwater (aquatic life, with higher ISO shot), foliage (trees and leaves), snow (people in white snowy background), and fireworks (higher ISO shot).

Besides that, you can also make special effect to your photos in SCN mode. The effects available for Canon PowerShot S95 are: Super Vivid, Poster Effect, Sepia, Black/White, Color Accent, Color Swap, High Dynamic Range, Miniature, Fish-eye, and Nostalgic.

In addition, you can produce panoramic (long) photos using software, by merging the continuous shot of Stitch Assist pictures.

Video mode

One of the nice features of Canon PowerShot S95 is its capability to shoot 720p HD video.
There are 3 picture quality options for video shooting in this camera:

• 1280x720, 24 frames/second (fps). You'll probably need a Class 4 or higher SDHC Card to get a smoother movie with this setting.
• 640x480, 30 fps
• 320x240, 30 fps

Special effects available for Canon PowerShot S95 video shooting are Miniature Effect, Color Accent, and Color Swap.

Good deal to buy Canon PowerShot S95 premium compact camera @ PIKOM PC Fair 2011

I have been eyeing for Canon PowerShot S95 premium compact digital camera since its launch. This is a good camera close to DSLR quality and standard with an easy-to-carry light-weight compact body. The camera is made in Japan (not made in China) and its official list price is RM1549.

This Canon PowerShot S95 camera received a lot of good comments and recommendations in the Internet. You can use it as a point-and-shoot in its fully automated mode, and there are also many manual controls for you to play around as if using a DSLR. If you don't play around with lenses (which will probably burn a hole in your pocket), perhaps S95 is good enough for you to take some good pictures.

Today I found a good deal in PIKOM PC Fair 2011 at KL Convention Centre, and finally bought it at the price of RM1299 using credit card. There are several exhibition booths selling this Canon PowerShot S95 camera, all selling at the price of RM1399 with different free gift goodies, and I only found one willing to sell at RM1299. The booth is located at Exhibition Hall 4.

Here is what I get at the cost of RM1299 (using credit card).

• Canon PowerShot S95 digital camera with all standard accessories in its box (made in Japan and with Canon Genuine DNA sticker)
• 1+1 years warranty
• Canon screen protector
• Canon camera's protective case for PowerShot series
• Toshiba 8GB SDHC memory card (5 years warranty)
• Canon digital alarm clock and MP3 player
• No-brand 170mm small tripod
• Fahrenheit (飞轮海) concert 2DVD pack
• Fahrenheit (飞轮海) recycle bag

Actually, the following are standard goodies that all Canon booths in PIKOM PC Fair 2011 will give. The rest need to bargain to get.

• 1+1 years warranty
• 8GB SDHC memory card
• Canon digital alarm clock and MP3 player
• Fahrenheit (飞轮海) concert 2DVD pack
• Fahrenheit (飞轮海) recycle bag

Forseeing that the recent earthquakes in Japan will probably affect its production and supply, I think the PIKOM PC Fair now is a good time to still get a good deal to buy made in Japan product(s) like this one.
