Raw or JPEG?

2 years ago

by Zul Murky in Photo, Photography Tips

RAW is normally only used when additional computer processing is intended. However, raw has numerous advantages over JPEG such as:: -

Higher image quality. The pixel value are more accurate and less posterization
Bypassing of undesired steps in the camera’s processing,including sharpening and noise reduction
The maximum amount of image detail compared the JPEG images. Raw image typically lossless compression, but JPEG image typically save using a lossy compression format.
Finer control. Allow us to manipulate more parameter by using RAW conversion software(such as lightness,white balance, hue etc..) and do so with greater variability.
More precisely highlight,shadows and saturated color.
The color space can be set to whatever is desired..
Different demosaicing algorithms can be used.
The contents of raw files include more information, and potentially higher quality, than the converted results, in which the rendering parameters are fixed, the color gamut is clipped, and there may be quantization and compression artifacts.
Large transformations of the data, such as increasing the exposure of a dramatically under-exposed photo, result in less visible artifacts when done from raw data than when done from already rendered image files. Raw data leave more scope for both corrections and artistic manipulations, without resulting in images with visible flaws such as Posterization.

Follow this advice if want to spend less time editing picture in front the computer by shot using high-quality JPEG Setting: -

Color space – keep Adobe RGB for maximum compatibility when it comes to printing and sharing your photo
Sharpening – try it out on various settings to get sharp and clear image on the computer without harsh pixellation on finer detail.
Saturation – make sure not make to far when ramp up the color saturation.
Hue - Some cameras have more adjustment than others in the JPEG processing menu,but this is on you will want to leave unchanged as it alters the hue of the color spectrum and can throw color way off.
Contrast – this is one adjustment can make in digital darkroom to boost impact, make sure you wake the setting up for really deep blacks and bright highlights in your JPEGs
Brightness – Leave it alone at the default setting. Images can appear washed out or suffer lack of contrast otherwise,

A well set-up camera taking lightly compressed JPEGs with the color and sharpening setting tweaked for maximum impact will result in minimum editing.

White Balance

2 years ago

by Zul Murky in Photo, Photography Tips

Another option to reduce editing time is white balance. To getting most accurate result for your photo is by choosing Manual White Balance setting. To get correct color temperature, select manual/custom white balance from the White Balance Menu, activate your camera’s calibration button and then shot of a grey or white area so the camera can calibrate the White Balance. Here the option you can choose from your WB option:

Sunny – a Brilliant all round outdoor setting
Flash -
Cloudy – great for dull days.
shady – produce warmer tones when shooting in shade.
Kelvin – Produce a WB according to the temperature of light in degrees Kelvin. Only use this if you’re positive of light temperature
Pre – best weapon of choice when the light temperature is mixed
Auto - leave it alone if you want retain control.
Tungsten – Use this for most indoor tungsten lighting
Fluorescent – prevent tube and strip lighting looking green.

e.g

Auto White Balance

Present White Balance = Tungsten

Known your ISO

2 years ago

by Zul Murky in Photo, Photography Tips

Selecting the correct ISO in-camera is probably the most critical setting you can make because it’s impossible to effectively reduce noise later without trading off sharpness and reducing contras. Choose the lowest ISO possible on your camera at all time for the best result. Pixels will be sharper,colors punchier and contrast at its best.

ISO 100

Choosing the lowest setting of ISO give the finest result possible as the sensor can perform at its optimum setting

ISO 400

at ISO 400 the camera increase the grain, or electrical sensitivity, of the sensor and the results are more interference.

ISO 1600

at this ISO, camera boost the sensor signal at the expense of sharpness, contrast and color balance.

4 reason to never delete image

3 years ago

by Zul Murky in Photography Tips

tips neh haku amek dari weblog luar negara dan penerangannya memang menarik, Jadi haku amek dan alih bahasakannya dalam bahasa melayu.

4 Sebab kita tidak patut menghapuskan gambar

1. Penipuan di LCD kamera : bercakap mengenal LCD, LCD sering digunakkan untuk melihat kembali gambar yang telah kita ambil dan disini juga ramai photographer suka menghapuskan gambar yang mereka ambil semata-mata tidak berpuas hati dengan kualiti gambar yang diambilnya. Mengapa perlu mendelete gambar tersebut sedangkan monitornya terlalu kecil untuk kita menilai gambar tersebut berkualiti atau tidak. Tunggu dan lihat lar di skrin komputer, disitu skrinnya yang besar memudahkan anda untuk menilai gambar tersebut. Adakah anda mahu menghapuskan gambar yang buruk di LCD tetapi terbaik di skrin komputer?

2. Jangan percaya pada jari anda: Jika kamu ingin menghapuskan gambar terus dari kamera, kamu mungkin terhapuskan gambar yang kamu tidak ingin langsung kamu hapuskan. itu menyebabkan kamu akan rasa sangat menyesal kerana terhapus gambar yang kamu rasa sangat2 berkualiti.

3. Bateri akan cepat lemah: Kurangkan reviewing,trimming and deleting gambar kerana LCD adalah tempat yang menggunakan banyak kuasa bateri. Bila banyak kuasa bateri habis ke situ, jadi sedikit tangkapan yang dapat kamu lakukan

4. Kamu akan menjadi lambat: Sekiranya kita sentiasa memberi tumpuan men’delete’ gambar dari mengambil gambar, kita akan terlepas saat terbaik yang berlaku disekeliling kita. jadi tumpukan pada gambar yang kita hendak ambil.
