How To Shoot Fireworks with DSLR

Hey peeps!, 

Ramadhan kembali, kini sudah masuk Ramadhan ke 11.. Pasti ramai ingin merakamkan gambar bermain bunga api.. Di sini ada beberapa tips menangkap gambar bunga api yg ingin dikongsikan bersama.

Many people do not have a clue on shooting fireworks. I was that many people until recently. Just want to share some tips with you guys on how to achieve the nice results.

Equipment requires;
1. a DSLR camera.
2. a tripod (the heavier the better)
3. Remote Release (Optional)

Other requirements;
1. Good location
2. Or good friends to book a very good location for you (I prefer this one :) )

Pre settings
1. change to manual focus mode.
2. put the lens focus to infinity
(with these two done, you will not loose time from camera searching for focus)
3. put on Manual Exposure mode.
4. with ISO 100, I recommend Shutter speed = 6-8 seconds and Aperture = F6-F8
5. mount your camera to the tripod and make sure it's steady.
6. if you know where the fireworks are going to be then, aim at that location.

Shooting
1. your ears will be your eyes. once you hear the shooting noise press the shutter release or use your remote. If you are further away then, you might need to time your shoots
2. leave your camera until it's done expose. (6-8 sec as you program it). For the first few shots you might need to re-adjust your position quickly, also quickly check the results and adjust the aperture value.
3. if there are a lot of big fireworks in the middle of your shots, you might need to use your lens cap to close the lens for awhile, the picture might turn up Over exposed.
4. again, hope for the best.

Repost | Mood Study :Apa itu Shutter Speed #1

Shutter Speed 

Shutter speed bermakna sebanyak mana cahaya memasuki kamera mengikut kadar masa atau kelajuannya. 

Kelajuan yg pantas akan membenarkan sedikit cahaya memasuki kamera dan boleh memberhentikan atau mengkakukan sesuatu pergerakan. 

Kelajuan yang lemah atau kurang, akan mendedahkan lebih banyak cahaya. 

Tapi ia tidak sesuai utk mengkakukan sesuatu pergerakan kerana kelajuan itu akan mengaburkan pergerakan objek tersebut. 

Sekiranya anda mahu memberhentikan larian seorang atlit, penunggang basikal atau apa saja objek yg bergerak, gunakan kelajuan yg pantas atau tinggi seperti 1/500 atau 1/1000 saat. 

Kelajuan pantas sebegini juga boleh membekukan percikan air atau kereta F1 di atas trek. Sebaliknya jika mahukan kesan khas pada gambar anda, gunakan kelajuan yg rendah seperti 1/50 atau 1/30 dan seterusnya. 

Kelajuan perlahan juga sesuai utk melakukan kaedah "panning", dengan mengambil gambar mengikut arah pergerakan subjek. Ia juga sesuai untuk mengambil gambar di waktu senja atau malam.

Mood Study : Tilt And Shift

~*~

Move the vertical slider on the right of the original photo to select the area in focus.

Use the "Preview" button to see the results, then click on the required image size and press "Download" when done to process the image and get a download link.

Site members get unlimited downloads up to 21MP (5700 pixel length/width) and can access over 50 bokeh styles, click here for details.

Processing and downloading hi-res images may take a few minutes, depending on original photo size and other factors. 

A download link to the most recent hi-res file processed this session will appear in the "Recent hi-res:" area. 

The size of the main selected area can be adjusted using the horizontal slider, from "narrow" (focusing on a small area) to "wide" (focusing on a larger area).

If you're using a display resolution over 1280x1024, try clicking on the "Large" button on the left to switch to large preview mode. You can then click anywhere on the image to toggle the display of the focus area selection.

Temporarily switching to large preview mode is also useful to see details in the image even if you're using a smaller display.

Tilt

24 mm lens that tilts (as seen above) as well as shifts

A camera lens can provide sharp focus on only a single plane. Without tilt, the image plane (containing the film or image sensor), the lens plane, and the plane of focus are parallel, and are perpendicular to the lens axis; objects in sharp focus are all at the same distance from the camera. When the lens plane is tilted relative to the image plane, the plane of focus (PoF) is at an angle to the image plane, and objects at different distances from the camera can all be sharply focused if they lie in the same plane. With the lens tilted, the image plane, lens plane, and PoF intersect at a common line;[4][5] this behavior has become known as the Scheimpflug principle. When focus is adjusted with a tilted lens, the PoF rotates about an axis at the intersection of the lens's front focal plane and a plane through the center of the lens parallel to the image plane; the tilt determines the distance from the axis of rotation to the center of the lens, and the focus determines the angle of the PoF with the image plane. In combination, the tilt and focus determine the position of the PoF.

Shift

In a subject plane parallel to the image plane, parallel lines in the subject remain parallel in the image. If the image plane is not parallel to the subject, as when pointing a camera up to photograph a tall building, parallel lines converge, and the result sometimes appears unnatural, such as a building that appears to be leaning backwards.

Repost | Mood Study : Apa itu Aperture #1

Aperture

Aperture berfungsi untuk mengawal kemasukan cahaya. Ia perlu diselaraskan untuk mendapat lubang atau saiz yg dikehendaki. Saiz-saiz aperture ini diukur dalam nombor 'f' atau 'f stop'.

Saiz aperture yg kecil membenarkan hanya sedikit cahaya memasuki kamera (melalui lensa) berbanding dengan aperture yg besar. Setiap nombor 'f' disusun dalam bentuk atau bidang skala aperture 2, 2.8, 4, 5.6, 8, 11, 16. Semakin besar nombor 'f', semakin kecil saiz bukaan aperture.

Apabila kita menukar dari f/4 ke f/5.6 atau f/5.6 ke f/8, cahaya yg memasuki kamera adalah separuh (1/2) dari cahaya nombor 'f' yg sebelumnya. Pertukaran ini adalah dari saiz aperture yg besar ke saiz aperture yg kecil. Penukaran dari saiz aperture yg kecil ke saiz yg besar adalah sebaliknya. Bidang skala aperture adalah berbeza antara sebuah lensa dengan lensa yg lain. Lazimnya, perbezaan ini bergantung pada harga dan model lensa serta kamera.

Pertukaran dari f/2 ke f/16 akan mengecilkan saiz aperture. Secara tidak langsung, cahaya yg memasuki lensa akan berkurangan.

Penggambaran ditepi pantai atau dibawah cahaya matahari terik memerlukan saiz aperture yg kecil (f/16 atau f/22). Ini bermakna untuk menahan cahaya yg berlebihan dari masuk ke dalam kamera, kita perlu mengecilkan saiz aperture. Apabila keadaan cahaya kurang atau di dalam bilik yang agak gelap, besarkan saiz aperture (f/2.8 atau f/2) untuk membolehkan lebih banyak cahaya memasuki lensa.
