Panorama photo

Hasn't been taking photos lately, other than a few gathering photo. But I am never a gathering-photographer type of person, I usually hand-off the duty to my friends. Haha.. Still, outing to Lookout Point, Cheras did resulted into something, well at least to me. We went for dinner in a restaurant called Panoramic View, and we get to view the panoramic view of KL. Took a few photo, came back and I used Photoshop CS3 to stitched the photos into a panoramic photo.

OK, what is panoramic view?
According to Wikipedia, a panorama is the wide-angle view of anything. It can be in painting, photography, drawing, and movie/video. I first encounter the word in photography. And indeed, I took my first panoramic photo a few years ago during my trip in Kota Kinabalu, Sabah. The subject I shot is Mount Kinabalu. It was taken using the family's old Canon Ixus 850IS, and i did'nt stitched the photo until lately. Here's the result from stitching three photos:

Photobucket

How can you take a panoramic photo?
Well, you can always buy a real panoramic camera, or you can do post-production using software like Adobe Photoshop.
For post-production, you will need to take some photo and stitch them together. For some models of Canon DC, there's already a function named 'stitch' when you are using manual mode. If there's no such function, feel no fear as ahguang is here. Tripod is very useful here as u can take multiple shots from the same height and spot, with more steadiness. The trick here is, if you are using a DSLR or prosumer, switch to 'M' mode, set the appropriate shutter and aperture for all shots. This is important to keep the exposure same. Then take a first shot, adjust your camera so that the second shot must overlap about 1/3 of the view covered in first shot, the third shot overlap about 1/3 of the second shot and so on until you covered the whole view.
Next, use your post-production software. I'd only tried Adobe PS3, so I can't comment much on the software, but its quite easy to use. Open your software, click 'File' >> 'Automate' >> 'photomerge', then select your photo, then click 'ok'. Just that easy and the software will do all the dirty work for you.

Here's the KL panoramic photo produced from the outing:

Photobucket

The photo is too long as it's stitched using four photos. Too bad too the most left and right side of the photo is blurred due to shaky camera when taking them. Must take better shots next time..

Stitching photos can also be used in some other creative situations. One of the example is as below, which is partly a failure:

Photobucket

I've seen some perfect portraits, examples here and here (from http://blog-blogsss.blogspot.com/) produced by stitching photos together, but mine above is surely not one of them. The exposure is different from left to right if you have noticed..

Hope you will enjoy stitching photos!

Compact? Prosumer? DSLR? Wat is tat?

In my very 1st blog entry i mentioned about having a camera, upgrading a camera into prosumer camera, and finally a DSLR (Digital single lense reflex camera)(or more commonly, the PRO-camera by many commoners... hehe). OK, but wat is all these things?

Most camera-users like to categorize digital cameras into three:

1. normal compact (or point-and-shoot camera)(i prefer the chinese name, silly's camera, more cute.. haha..) (acronymed as DC below)
2. prosumer camera or semi-pro camera
3. DSLR camera or pro-camera

Each type of camera has their own advantage and disadvantage. Althou i am not very clear about it, i wil try my best to explain it.

In simple words:

For details or complete post, click the 'read more' below...


Normal digital compact(DC) are the common camera v normally use or saw ppl using. For example, my family's 1st ever DC is Nikon's Coolpix S3.

Ofcoz the obvious advantage of DC is its relatively easy to use. The fully automatic control of the camera ease the user. All u need to do is juz look into the screen, half-press shutter for the camera to auto-focus onto object, full press to take photo and checking ur photo. Not satisfy then u can delete and re-snap. Tats all. Then, the small size of DCs made them easy to be carried evywhere witout the worry of camera weight and size .

Summore now-a-days DC price ranges from 200+ to 1k+, evy1 can buy a camera based on their abilities and requirement. In order to compensate the lack of photography skills among the users, cameras have also been equiped wit several useful semi-auto function, for example the Macro-mode(to take close-ups of small things), Night mode, Portrait mode, In-Door mode.. (if u wanna noe bout diff btw each mode, leave ur comments to tel me bout it..) The higher end of DC also come wit manual mode, where it enables the user to haf more controls on shooting. As far as i noe, some Canon models provide 'long shutter' mode where u can choose shutter speed from 1-15 seconds! Snap, snap and snap.. There comes most of the photo in FB album...

This is one of my better photo snapped using Canon IXUS 850:










Well, the downside of DC is ofcoz the image quality taken is not as good as Prosumer and DSLR in terms of exposure and noise performance. But if u cannot differentiate the quality/not so particular about the quality then its find. Inability in changin lens of coz would be de biggest limitation of DC.


Prosumer camera, or commonly known as semi-profesional camera. The word "ProSumer" suggest that it's used by Professional Consumer. Erm.. to me a professional is professional, but not a consumer anymore.. haha.. so oni those who has a higher requirements towards image quality than those DC rookies, but stil not PRO enough..

Prosumer lies between DC and DLSR. It has some advantages from the two, and also disadvantages of both. It offers more manual controls which is not available on DC, like aperture-priority, shutter-priority, depth of field priority. The image quality is better than DC as the lens has larger aperture and better sensor. The size of prosumer cam r generally smaller than DSLR, slightly bigger than DC.

Canon G11, the ultimate prosumer cam:

The downside is, the mounted lens cannot be change like DSLR. There is no manual focus for prosumer cam too, which is an important property for producing better image. The lower price is more expensive than most DC, and the expensive ones can easily by-pass entry level DSLR. Conclusion is, its not supreme in function wise, but the mobility and pricing are also not an advantage over DC. It'd be hard for some to choose prosumer, as the lower priced prosumer r not worth buyin compare to high-end DC wit similar function and price, then the higher level prosumer r not comparable with entry level DSLR.


Then the DSLR. A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that uses a mechanical mirror system and pentaprism to direct light from the lens to an optical viewfinder on the back of the camera. (from wiki)

Too complicated?
In simple, DSLR is a digital cam that looks more pro than the others... haha.. Tats wat you're telling others when u're holding tis kind of cam. Hahahaha..

Well, the advantages of DSLR had also been mentioned above. Better image quality (as better sensor provided), more manual controls to gif better image, ability to change lens, look professional.. Actually the advantage of DSLR is due to its sensor and lens. I wont explain on sensor as i m not clear of it myself too. For lens wise, i can tell u tat many lens r specifically designed for specific use. There are lens specifically for taking portrait(the prime lens), sports photography(zoom lens), macro/micro(wide lens) etc.. U can suite urself to take better photo wit a proper lens of ur choice. Ability to manually focus the image is also a big advantage, as u can blur out background to extrude ur object/ focus on things which are hard to the camera to autofocus.

Canon EOS 1000D, my 1st and oni DSLR..

Ofcoz, better quality=higher price, DSLR is more expensive than the two categories. It can ranges from RM1.8k to more than RM30k!!(as far as i noe la..) (i bet there r some cam which is more expensive!) The size of DSLR is also bigger. Manual control meaning more difficulties in balancing various factors to produce good photo. The biggest downside is, once u r into it, u wil be spending more on lens, external flash, battery grip, filters, hood, then better camera, lens.. the vicious cycle nv ends.. haha..

Below r some links to the official webpage of digital camera companies in m'sia. If u r interested, u can read the specification of each camera there! Enjoy!
