Canon SX 130 IS Raw Developing : Image Distortion Problem Solved

February 11, 2012 in photography

When I was a newbie for using the firmware upgrade in my Canon SX 130 IS , I found so many problems while developing the RAW files. I had no problem with Macro shots or normal shots.But I faced a lot of problem with zoomed shots .

Whenever , I used to take zoomed shots in raw mode, it was fine but when I used to develop them , I faced image distortion problem .I tried to check tall the settings in the CHDK virtual menu to solve the issue .But i didn’t find any solution .

However , RAW files come with different extensions and I use .CR2 extension. To develop a RAW file, it is required to take one shot which will develop the Raw file and compress it to a JPG file . However , one person has no problem with normal shooting or shooting with macro mode . But there is a problem with zoomed shot and the main problem is the developed image file gets distorted .

Is there any way to solve the issue ? Yes, there is a solution . However , you won’t get any solution Neither from the CHDK virtual menu or from the default camera settings . I solved it myself and I just did a trick.

And the solution is here . An image file taken with zoom must be developed with the same zoom .So here you need to remember the actual zoom you used to take a snap because when you are going to develop the Raw file , you need to take the snap with the same amount of zoom to avoid the image distortion problem .

What The Hell is This RAW Image Shooting : Here is What You Should Know

February 5, 2012 in photography

So …… You don’t know what is a RAW file is and why you need it . Ok . Listen – In this part , we will discuss about the possibilities with JPEG file extension and Then we will discuss about why shooting RAW images .

Whenever , we take an image , the image is generally saved with JPEG extension .

When we take an image with JPEG extension , our cameras write the whole information on the SD Cards for once.

We are able to change the color information such as converting the color photo into blank & white photo from our PCs or doing any things like changing the Tint or Color Temperature etc using any photo editor like Adobe Photoshop or GIMP Shop or5 other photo editors.

But with JPEG shooting we have less capabilities and possibilities . Why ? We can not avail all the features if we shoot images only with JPEG file extension .

Let me tell you with an example . Suppose ,we have a subject to shoot and we have very low time .We just want to take the snap in different modes such as Normal Mode, Black & White , Sepia Mode , Color Accent Mode etc. or taking the snap emphasizing the Blue Tone or Green Tone or Red Tone Or setting the white balance manually .So what to do ? Can all these things be set at once ?. Your answer is NO when your subject is constantly moving .

Here is the why RAW shooting is really required . A RAW file is the file which is not processed at first and which carries all the information . A RAW file is larger in size than normal JPEG file . Different Cameras produces different sizes of RAW files .

A  RAW file may be 18.7 Mbs in size or a bit less or more and a JPEG file may be 3 – 4 Mbs in size or a bit less or more . So some more information is there in the RAW file and that’s why the file size is larger the JPEG file.

If you Shoot one RAW image with normal mode , you can produce more snaps in your Cam with different settings and different modes from the snap .You just don’t need to take the various shots with different modes and settings at that time . This thing can be done later .

Suppose , you took a snap with RAW extension and you took the snap in normal mode .You have just followed that your subject is wearing a red dress and you want to keep the red color in the snap and change the rest of the colors into black and white .Can you do this ? If you ask me , my answer is yes . Not only me , everyone can do this with the help of RAW image shooting .

This is the main reason why professional photographers like the features of RAW Image Shooting .

This RAW files are developed in the Camera . Even this is possible to change the Exif or Meta Data data in a snap .

It’s a kind of digital Negative which enables you to produce different snaps with different modes or settings from the same shot.Whenever a RAW file is developed it produces a JPEG image file .But the RAW file remains intact and you can avail more variations from a same shot .

To explain it with a better view , We are going to watch some snaps .All the snaps have been generated from a single shot and the shot was taken in RAW mode .
