High-Speed Continuous Shooting and Predictive AF

The autofocus (AF) technology of Canon's EOS series of SLR cameras debuted in 1987, making an impact on the market for its speed and ease of use. Since that time, Canon has continued to develop and evolve AF technology into a digital camera legacy: from its initial AF with a single focus point at the center of the viewfinder to 3-point AF in 1990, 5-point AF in 1992, and 45-point AF in 1998.

Canon's new Area AF features 19 Cross-Type and 26 Assist AF Points.^*1 While the system includes the same number of 45 focusing points as in conventional Area AF, all 19 selectable points are high-precision cross-type points, in which vertical and horizontal line components of the subject are simultaneously detected by cruciform distance measurement. Vertical lines are detected with professional-class specifications, conforming to the large-diameter lens group of f/2.8-4 distance-measuring light flux. For horizontal line detection, the 26 assist points conform to f/5.6 light flux, effectively assisting the focusing points selected by the photographer and ready at all times to capture subjects adjacent to selected focusing points. This greatly contributes to the faster capture of moving subjects, particularly when shooting continuously with the predictive AI Servo AF at the high speed of approximately 10 frames per second.

This technology was realized through Canon's Area AF precision optical system and unique high-sensitivity new Area AF sensor,^*2 along with the development of sophisticated AF computation algorithms.

Depth of Field

Depth of Field (DOF) pada fotografi adalah salah satu cara yang paling bagus untuk menonjolkan subject foto dan menjauhkannya dari background yang dapat mengganggu. Ada beberapa cara untuk mendapatkan Depth of Field.

Posisi dari subject
Cara paling gampang adalah memposisikan subject sejauh mungkin dari object-object dibelakangnya.

Gunakan portrait mode
Umumnya camera digital memiliki mode portrait, ditunjukan dengan dengan icon bergambar kepala orang. Ini adalah simbol portrait mode. Jika Anda kurang yakin bermain dengan aparture, memilih mode ini adalah pilihan bijaksana dan akan membantu Anda menangkap foto portrait yang bagus. Portrait mode akan menggunakan aperture yang besar (nilai f kecil) dimana titik focus akan lebih kecil (menghasilkan foto yang bokeh).

Aperture Priority mode (click disini untuk detailnya)
Ini adalah cara yang paling bagus untuk mengatur Depth of field dan memastikan foto anda ter-exposed semestinya.
Dengan memilih mode yang ditunjukan dengan huruf 'Av', Anda bisa bereksplorasi dengan aperture. Anda bisa melihat artikel tentang aperture disini. Mode Av ini adalah mode semi otomatis, dimana Anda hanya mengatur aperture, dan setting lainnya akan berjalan otomatis, ini akan memastikan foto Anda terekam dengan baik.

Cobalah untuk merubah-rubah aperture, dan perhatikan efek yang terjadi pada backgroundnya. Selamat ber bokeh ria. ^.^

Repetisi dan Pattern pada Photo

Reps can be tedious in everyday life, however, when the reps were caught on camera, can make a good photograph. You only need to be more observant and attentive, then you will be surprised, that there was a lot of reps and you do not use it to produce images of the 'cool'. There are two techniques for treating the repetition, repetition is affirmed or change the reps.


reinforce Pattern
Fill your frame with a repetitive pattern will make the feel was great and lots of photos. The key is to zoom as close as possible to the pattern is to meet the frame to be captured.

Some examples of the faces in the crowd, bricks on the wall, wheel motors at the same angle, and others.

Change Patterns
The idea is to capture the change of a recurring pattern into your photo. Example, you know M & M chocolate candies, you can shoot a blue M & M M & M among the hundreds of red.

Sometimes the pattern is broken there by itself, sometimes you need a bit trying to make a broken pattern.

Broken pattern can be anything, such as changes in color, shape, texture, or simply by throwing an object over it.

Another thing to note is, focal point, broken pattern is where the focus of your photos are.

Matte vs. Glossy

Mungkin teknik foto Anda keren, komposisi bagus, angle OK, tone manteb. Tapi saat dicetak, tidak sesuai keinginan Anda. Mungkin artikel ini sedikit membantu Anda untuk mempertimbangkan jenis kertas foto yang akan digunakan.

Glossy - Pros:

• Foto akan nampak cemerlang
• Warna kuat
• Gambar Tajam (untuk subject dalam focus)
• Tidak menghasilkan texture-look ketika di scan

Glossy - Cons:

• Mudah meninggalkan jejak tangan
• Membersihkan jejak-jejak diatas memerlukan photo cloth atau cairan pembersih
• Memantulkan cahaya, kadang sulit dilihat dari sudut tertentu

Matte - Pros:

• Jejak tangan tidak terlalu kentara
• Nampak profesional, terutama untuk Black and White fotografi
• Tidak memantulkan cahaya

Matte - Cons:

• Foto nampak 'grainy'
• Warna kurang kuat
• Saat di scan, texture akan ikut ter-scan
