RAW adalah hasil imej didalam kamera yang merakam subjek atau objek dalam kualiti asal yang ebih besar. Imej yang terhasil dianggap seperti bahan mentah yang belum diolah sepertimana daging yang baru dibeli dipasar. Untuk memasak daging tersebut, pelbagai ramuan dimasukkan seperti rempah, garam, cuka, gula atau apa sahaja perasa. 

Begitu juga RAW. format yang digunakan untuk merakam imej dengan kualiti hampir 100% sepertimana yang kita lihat oleh mata kasar kita. Imej yang terhasil masih boleh dibetulkan menggunakan perisian yang disediakan oleh pengeluar kamera sebelum dijadikan ke format jpeg. 



Saiz yang terhasil dalam format RAW lebih besar berbanding jpeg. Ini bermakna, imej tersebut masih boleh dilakukan editing tahap maksimum tanpa merosakkan kualiti asal imej tersebut. 

Ramai jurufoto yang merakam imej menggunakan format RAW betujuan membetulkan kembali kesilapan WB, Brightness dan seumpamanya selepas imej tersebut dirakam. 

Contoh perisian yang boleh memproses format RAW ialah Nikon Capture NX2, Adobe Camera Raw (ACR - sebahagian dari Adobe Creative Suite). Adobe Lightroom, Apple Aperture dan Canon Digital Photo Professional (DPP). Lain-lain perisian ialah Google Picasa, Windows Explorer, Mac Finder, Photomatix dan pelbagai lagi. 

Manakala jpeg pula adalah format foto yang tersedia untuk dicetak. Setting yang telah ditetapkan tidak boleh diubah setelah imej tersebut dirakam.


Berikut merupakan contoh-contoh perbezaan RAW dan JPEG.

10 PERKARA PENTING UNTUK JURUGAMBAR PERKAHWINAN 


SUMBER 


Top Ten Do's & Don'ts for Wedding Photography

Do use a telephoto lens for portraits! A wide angle lens is often the worst choice for a portrait style photograph of a person or small group of people. It is much better to get a telephoto lens or use a zoom lens with telephoto capabilities. A wide angle lens will enlarge the nose of a subject and often stretch the proportions of a face or body to make the people look unflattering. A telephoto lens compresses the face.

Do use a macro lens for extreme close-up portraits! Sometimes just a photograph of the bride's earring, or grandpa's beard and smile, or a baby's nose, or even a child's eyes can make a memorable and spectacular portrait. Consider that the very best optics to accomplish this with extreme detail and controlled depth of field is a macro lens.

Do use a super wide angle lens to photograph large groups. At a wedding or family reunion, it is often necessary to get a large number of family members into one picture. Just be careful to compress all the attendees into just a few rows of people because those in the back may look smaller than those in the front row.

Do bounce the flash off the ceiling for a natural look. When taking people photographs, strong shadows and red-eye are constant problems. If your flash adjusts and can bounce off the ceiling, try it the next time the ceiling is a shade of white and is 8 to 10 feet.

Do eliminate red-eye by taking a second picture! A great trick for getting rid of red-eye is to quickly make a second exposure right after the first picture was taken! This gives the first flash a chance to make the subject's pupils dilate making the second portrait perfect. And with today's digital cameras, there's no waste in exposing another image!

Don't get caught without "fast" lenses in low light. A lens with a maximum aperture of around 2.8 is great to use in low light situations, like photographing during a wedding in a church where on-camera flash is prohibited. It's important to find a lens for this purpose that has a "fixed" maximum aperture and NOT one that varies (for instance, a zoom lens that is labeled f/1:2.8 would be preferable over a lens that says f/1:3.5-6.3).

Do use compact zoom lenses for vacations. A wide angle to telephoto zoom is ideal for traveling light on trips because it is possible to just bring one lens. My favorites are 18-200mm and 28-300 mm. These lenses both have a maximum aperture that varies as the lens is zoomed from wide to telephoto, but their small size and weight are great advantages.

Don't get caught without batteries! Use NiMH rechargeable batteries for uninterrupted power. Today's NiMH batteries are more powerful than ever in digital cameras which require AA batteries. They are inexpensive, long lasting, and charge quickly. And it is a good idea to carry a backup set of batteries and a small charger in your camera case. 

Don't shoot without a lens shade! Many use clear glass UV or haze filters to protect their lenses in case of bumping them into something, but shooting through a clear filter can often be like photographing through a window. Instead, use the supplied hood or shade that was manufactured for the lens; it will eliminate flare in many cases and acts as a barrier against damage.

Do use the power of your zoom lenses! If you are across a room at an event, such as a wedding, a zoom lens can get you in closer to the action without having to run in and possibly miss the shot.

Maksud Bokeh Dan Contoh Bokeh Yang Awesome!!




Sumber : Wikipedia
In photography, bokeh (Originally /ˈboʊkɛ/,/ˈboʊkeɪ/ boh-kay — also sometimes heard as /ˈboʊkə/ boh-kə, Japanese: [boke]) is the blur, or the aesthetic quality of the blur, in out-of-focus areas of an image. Bokeh has been defined as "the way the lens renders out-of-focus points of light".  However, differences in lens aberrations and aperture shape cause some lens designs to blur the image in a way that is pleasing to the eye, while others produce blurring that is unpleasant or distracting—"good" and "bad" bokeh, respectively.  Bokeh occurs for parts of the scene that lie outside the depth of field. Photographers sometimes deliberately use ashallow focus technique to create images with prominent out-of-focus regions. Bokeh is often most visible around small background highlights, such as specular reflections and light sources, which is why it is often associated with such areas. However, bokeh is not limited to highlights; blur occurs in all out-of-focus regions of the image.
