Shutter Unit

Dengan makin terjangkaunya harga entry level DSLR, hobi fotografi makin banyak diminati dan mulai menjamur di Indonesia. Saya pun termasuk korbannya. ^.^

Saat membeli kamera DSLR, dalam pikiran saya yang masih awam, saya bisa jepret sesuka hati. Toh, tidak menggunakan film, jadi biaya belajar foto murah. Betul, tidak menggunakan film, hingga biaya pembelajaran fotografi lebih murah. Tapi ada satu hal yang tidak terlintas dalam pikiran saya, ternyata shutter unit dari kamera DSLR itu ada usianya. Hingga, suatu hari, saat hunting bersama teman, kameranya tiba-tiba error. Image preview dapat berjalan dengan baik, namun saat pada mode memotret, terdapat pesan error mengenai shutter error.

Apa sih shutter unit ini? shutter unit adalah bagian kamera yang berguna mengatur exposure yang akan diterima oleh sensor. Bekerja dengan  terbuka dan menutup sesuai kecepatan yang kita set pada kamera contoh 1/4000 detik, maka shutter akan menutup dengan kecepatan 1/4000 second.

Penggunaan shutter ini tercatat dalam data exif dari setiap image yang telah terekam. Data ini dapat dilihat dengan menggunakan software seperti xN view.

DSLR entry level diuji hingga 50 ribu kali jepret, dan DSLR prosumer bisa dipakai tanpa masalah hingga 100 ribu kali memotret. Untuk level pro diatas 150 ribu kali jepret tanpa masalah. Mungkin angka ini variatif untuk berbagai merek vendor.

Hal yang dapat membuat shutter unit mogok kerja adalah:

• Penggunaan shutter speed yang tinggi, shutter akan bekerja lebih keras.
• Burst, alias continues shooting, shutter Anda juga bekerja keras.

Bila Anda punya habit, jepret aja bleh.. nah, mungkin mulai sekarang sudah mulai diperhatikan, mind before shoot, selain membuat Anda lebih profesional dalam mengambil angle dan moment, Anda juga merawat kamera DSLR kesayangan Anda.

Info tambahan, di internet, saya temukan, penggantian shutter berkisar 100-200 USD (Canon), saya belum riset untuk price kamera lainnya (kebetulan saja saya menggunakan canon)

New Canon 600D

Introduction
Canon 600D is 550D with articulated screen plus EOS 60D features. Canon 600D is a 'Basic +', simple, image adjustment with which the user can change the look of their images and adjust background blur without the need for very technical.

600D is also accompanied by '60D Creative Filters', such as toy camera, fisheye and miniature fake-looks. 600D can also set up off-camera flashes wirelessly, including the Speedlite 320EX and 270EX II.

Changes were also made ​​in the automatic mode pointer icon, changed from the 'green box' to 'A +', which according to Canon, this mode will analyze scene in the camera and adjust exposure parameters and better image-processing and produce more accurate color output.

Continuing with the theme, beginner-friendly, 600D come with guide that will display a brief description of the functions to help beginners learn to use it.

In terms of video capturing, 600D provides the stitching ability to add movie soundtrack. So we do not need to do video editing again.

Which is unchanged, still using the sensor 600D 18MP APS-C CMOS. So in terms of image quality, there has been no renewal.

Can be concluded, 600D camera with features that are very nice on entry level, we can say "the disparate is thin" when compared to the EOS 60D. (More difference in terms of ergonomics and handling).

Panning - Motion Feel

Panning is a photographic technique used to capture the effect movement of the object. Commonly used for sports photography. With the swing that follows the movement of the rotating object, we can capture the object and make the background blur that makes us feel the movement of the object.

These tips and terms
Tv or S mode, or shutter priority, where we manually set the speed of the shutter, and the camera will automatically adjust the aperture.

Setting the AF or AI Servo Auto Focus or C (Continues Focus) (the term may be different on different cameras)

Setting Speed ​​No exact formula for this, depending on the habits and movements of the object itself. There are comfortable with high speed is more accustomed to the lower kecepetan. Advantage at high speed (1/60) is the risk of blur on the opposite axis of the direction of panning (eg, panning direction is horizontal, then the opposite direction is vertical) can be reduced.

Swing, after all prepared, do swing to follow the movement of the object and click, capture your object.

Tripod or monopod, use this tool to get more clear on the object. When using a tripod, make sure the tripod has a head with the facility to lock the horizontal axis.

Tips Lens, you can use any type of lens. To note, when using a zoom lens, a little movement can cause motion blur on objects. In addition, when the autofocus of the lens is slow, do prefocusing at the location where you want to catch the object, before you shoot the object.

Tips Location, avoid high backlight, use the location of a rich background colors to add more motion effects.

Tips on practicing, use the first large object, like a car to practice swing.
