RAW or JPEG ... ??

Pengguna kamera DSLR atau Prosumer sering dihantui pernyataan mendasar sebelum memulai memotret: format file apakah yang akan saya pilih, JPEG/JPG ataukah RAW ??

Pada dasarnya kebanyakan kamera bekerja dengan cara seperti ini: Saat kita memencet tombol shutter, kamera akan merekam data mentah yang diterima sensor (baca RAW). Berdasar data ini, software di dalam kamera akan memutuskan beberapa parameter, misalnya seberapa jauh foto perlu dipertajam, setting white balance mana yang sesuai, berapa level eksposur yang dipakai, seberapa besar saturasi warna-nya dan seberapa besar beda kontrasnya dll. Setelah data tersebut diolah oleh software di dalam kamera ini selanjutnya dikirim ke memory card dalam bentuk file JPEG.

Beda RAW dan JPEG
RAW adalah data mentah yang langsung ditangkap sensor sedangkan JPEG adalah data matang yang sudah diolah oleh software kamera. 
Format RAW membuat kita bisa mengubah-ubah parameter pemotretan sesuka kita. Dengan bantuan software pengolah RAW (photoshop, lightroom, GIMP, ACDSee dll), kita bisa mengubah nilai eksposur, white balance, saturasi sampai kontras  untuk kemudian menyimpannya dalam format yang lain: JPG atau TIFF. 
Format file JPEG juga mengijinkan pengolahan foto yang lumayan banyak, hanya hasil dan cakupannya tidak seluas dan sebaik RAW. 
Tersedia juga format TIFF, namun sebaiknya tidak perlu dipakai karena ukuran file-nya sangat besar.

Keuntungan memakai RAW?
  • Kita bisa mengotak – atik file mentah menjadi foto matang sesuai keinginan kita.
  • Opsi pengolahan foto menjadi jauh lebih banyak sehingga mereka yang berjiwa super kreatif lebih terpuaskan
  • Informasi yang tersimpan lebih banyak  (jika anda memilih JPEG, kamera akan menghilangkan sebagian kecil data untuk memperkecil ukuran file dan mempercepat  proses pengolahan)
  • Kualitas foto secara keseluruhan lebih baik, ini berkaitan dengan adanya kompresi jika memakai JPEG

Kerugian memakai RAW ?
  • Memakan kapasitas hardisk dan memory card. Karena tidak ada proses kompresi, maka ukuran file RAW jauh lebih besar dibanding JPEG (sekitar 3 sampai 4 kali lebih besar)
  • Memakan waktu lebih banyak. Baik selama pemotretan (mengurangi kecepatan kamera terutama dalam mode burst) maupun selama pengolahan di komputer (karena ukuran file-nya)

Jadi Format Apa Yang Sebaiknya Dipilih?
  • Jika anda punya hardisk diatas 500GB, memory card minimal 4GB dan sedang memotret moment (atau orang atau tempat) yang istimewa, pilihlah mode RAW
  • Jika anda sedang memotret hal “biasa” atau butuh memotret berondongan (burst), atau hanya memiliki kapasitas hardisk dan memory card pas-pasan, pilihlah mode JPEG.
  • Atau ambil jalan tengah jika anda punya kapasitas hardisk dan memory card yang berlebih: pilih mode RAW + JPEG (kamera akan menyimpan 2 format sekaligus)

Practice Product Photography #3


On photo above i'm using light painting method. Exposure time is about 1-5 second on very dark room and for the light source I'm using flashlight about 1 second on top of eye glesses. I'm using my favorite 50mm lens, tripod, and shutter release (or timer mode work well). 


In this photo I simply use my 50mm attached on ext-tube. With flash and diffuser on top of my camera. I'm using macro technique to make this photo. Because I want to expose the detail and scratch on this gas lighter. 

Hope you all enjoy my photo ... :D

Syrphus Ribesii





Syrphus ribesii is a very common hoverfly found along hedgerows, in garden and woods. Adults feed on the nectar of flowers, while the larvae are predators of aphids. This hoverfly has multiple broods and adults are seen throughout spring and summer, while the larvae survive the winter as pupae. It creates a hum when resting by vibrating its wings.

Syrphus ribesii has roounded, black body with pattern of yellow spots and brands. This is just one of large group of very similar hoverflies which can be found in a variety of habitats. Many hoverflies are very difficult to identify, requiring microscope to look at tiny character including the shape of the veins in the wings. But macro lens nowadays are capable to do that.

EV Compensation Explained

What is EV button and what it does...???


To put it simply, the EV button allows your to quickly underexpose (darken) or overexpose (brighten) your image. How it works is pretty simple. When you’re taking a photo, the camera’s job is to adjust itself by changing the shutter speed and/or apperture to properly expose your shot so that it’s not too bright or too dark. Some cameras do this better than others but that’s another story. When you play with the EV button, what you’re doing is telling the camera to either brighten or darken the photo from the optimal exposure it perceives. 

You can use the EV button in P (programed auto), S or Tv (shutter priority) or A (aperture priority) modes.

In P mode, the camera will adjust the EV by changing the shutter speed and/or the apperture. 
In S/Tv mode, since you set the shutter speed manually, it will adjust the aperture to compensate. 
In A mode, the camera will change the shutter speed since you manually control the apperture.
NB: You cannot use the EV button to under or overexpose your photo in M (manual) mode since you control both the shutter speed and aperture manually.
When to Use EV Compensation

- When you need more shutter speed
- When your subject is brighter/darker than your background
- Bright sky

So basically this EV button function is same as shutter speed and aperture in manual mode.

Angry Spidey



This spider's face reminded me angry bird game on android. Black shape above his eyes like angry eyebrows. Just like the characters in the game angry bird. As well as huge teeth like rabbits makes it even more funny. But this is also the type of spider that hard to find. I've photographed a lot of spiders but this is the first time I found a spider like this.

I hope you all enjoy my photo... :)

Set of Damselfly

Damselfly by Kristanto Anggoro on Viewbug

Demoisele Again by Kristanto Anggoro on Viewbug

When I photographed this damselfly, my biggest mistake is the use of flash. Which makes the wings of the damselfly is not transparent. It very difficult to photograph damselfly using ext tube and 50mm. Which makes it difficult is the distance between the lens very close to the object. While the damselfly it self very aggressive and unfavorable locations makes it more difficult.

But I will not give up. I'll try it again one day and I'm sure I'll be able to make a good photograph damselfly. And in the meantime I hope you all enjoy my photos of this damselfly... :D
