Pay attention to White Balance

Most of the professional photographers make sure, white’s stay white. Often we are challenged with tricky lighting conditions which make deciding on a white balance difficult. JPEG shooters are more vulnerable since the scope for colour correction is limited in post-production.

However, even if you’re a RAW shooter it is important to get WB close to perfect right in the camera. A bride on her wedding day looking resplendent in her saree would be disappointed if you supply her with photographs wherein her saree colour is way off. It happens quite a lot in wedding photography, purples turn into blue. Since the amateur photographer is lost in other aspects(composition, lighting etc) of the photograph, it(WB) gets easily hood-winked. However, the bride and her family are the first to spot the mistake. In rare cases, they might not complain but you are sure to lose the client for a future photo assignment.


In order to avoid such an unpleasant scenario, one should be careful about the WB during shooting. Often WB is a subjective topic. Some like their pictures to be warmer whereas others opt for the most neutral colours. I fall in the latter category. I do tweak the WB to one other than the prefect when I feel the need for it. Often I proceed with setting the camera’s white balance to a ‘preset’ closer to the lighting condition I am shooting in. When I shoot under mixed lighting conditions, I make sure to get a “Grey Card” reading from my subject. Of-course, I always shoot in RAW. Combination of these two methods give me a head-start when I have the photographs over the computer post shoot. Most often, the WB is spot on or close enough. The little adjustment(if required) is easily handled in post-production.

Installing software under Linux doesn’t require one to hit the console anymore. Thanks to the graphical package managers available which have made the job of installing, uninstalling & updating software packages a child’s play. Still knowing how to manage software via console is necessary to make yourself a competent Linux user. In this first post I will cover installing software under Debian Linux. I will follow this post with installing softwares on Redhat, installing from source etc.

Wildlife genre has been always difficult for someone like me who has a point & shoot(P&S) camera having a limited zoom range. Even though my Canon SX100 IS has 10x optical zoom, it still fells way short when it comes to photographing wildlife. Again the slow contrast detect focus system on my P&S camera is not the best when it comes to locking focus on birds in flight or even on one that are perched on branches of tree surrounded by other branches as obstructions. To aggravate the difficulties further, my camera has even developed a problem wherein the camera refocuses when you depress the shutter from half press to full press position(Out of 5 times this happens four times). I’ve tried hard to shoot wildlife before & even have succeeded in capturing them but still I was not overtly satisfied with the results. Yesterday, I had a visitor in my backyard. It was a crow but it was not the normal specie which we see in abundance. The crow was unusually big & almost entirely black. I ran around my home & quickly grabbed the camera and returned near our window facing at backyard.

Now that you have chosen the right linux distro, its time to get hold of it. Here are the many ways to get the linux distro up & ready to install or try on your machine.

  • Direct HTTP or FTP : Most of the linux distros can be downloaded from their official website or from websites which mirror them. This(HTTP or FTP) is the most popular way of downloading. However the main drawback of this method is that if the server doesn’t supports to resume download then you have no luck but to download all again. Also if you have a fairly slow Internet connection then downloading big DVD sized distro make take days.
  • Torrent : After Direct download, Torrent download is another good way to download linux distributions. Not only you can resume paused or broken downloads but torrent also provide faster downloads especially if the peers ratio is higher. Torrent download is my personal favourite since one can download a full CD or DVD sized distro on mobile phones which saves a lot of power than keeping a computer powered on for several hours.
  • Media Distribution Programmes : If you have no Internet connection at your disposal or have a capped Internet plan (Plan having data download restrictions) then distribution programmes are your best bet. You can find a form which you simply need to fill with your details on the distro’s website & then you will receive your distro via courier free of charge. However it takes time to make the distro’s CD/DVD at your doorstep since it needs to be posted & needs time in transportation. If you are impatient to try out the distro as soon as it releases this method is not suitable for you. Also sometimes your request may be rejected if the organisation feels you are misusing them. I request you to order only the amount of media’s you need since ordering any surplus & not using them is not right as there are cost involved. The suppliers need to bear the cost of the media & shipping charges. Though you get the media for free but the suppliers spend a huge amount for your convenience. So please do not misuse this service.
  • Magazines : If you are a subscriber of any Computer or Linux oriented magazine then you can get the most of linux distros bundled along with. Some magazines provide the CD/DVD image of the distro while some provide you with a bootable disc. Here again you need to keep patience as the magazines due to their monthly nature provide the distro almost a month late. Due to this if the distro release date doesn’t fall within the first 15 days of a month it is skipped in the next month’s issue.

Burning the downloaded Image to Media:

Now that you have the distro ready on your hard drive, its time to burn it onto a CD or DVD. You should get a .iso file. Simply double click on this file & your default CD burner program will launch prompting you to insert a blank CD/DVD. Load the media in the drive & wait till the burning process completes. Congrats. You have successfully burnt the media which can be used to install your chosen linux distribution.
