GIMP is a good free software for photo-editing. It has most of the capabilities you will require of its commercial counterpart Adobe Photoshop. What’s more with the right plugins, you can extend its capabilities. Here I’ll tell you about some GIMP plugins which will primarily be of interest to photographers. They will make your photo work-flow easier & faster.

Vignette – As the names suggests, this adds a vignette to your photo. Vignette can be used creatively to allow viewer’s eye to stay within the frame. Most of the photos will benefit from a small amount of vignette. The vignette plugin allows you to choose parameters like vignette colour, softness, darkness etc. It does its job very well.

Lomo – Want to mimic the look of a LOMO camera? This plugin will do it for you. It saturates the colour, adds a vignette(there is also an option for double vignette) & some other parameters for fine-tuning the output. Have fun!

Split Tone – Split toning is another beautiful effect. This plugins lets you select the two colours for split toning(as oppose to just two offered by most other programs) & end up with results beyond your imagination. Give this a try.

Darla Contrast Fix – This plugin aims to normalize the contrast in the photograph. With the right settings, it can make a photograph. However, this plugin requires some practice & knowledge of the parameters before one can get consistent results regularly.

National Geographic – Have you always wondered at the quality of the photos published by Nat Geo? They are sharp, contrasty & look as if edited by professionals. This simple plugin will put the same power in your hands too. This is a great plugin & as Darla Contrast Fix, this too requires practice before you’re able to get consistent results on a regular basis.

G’MIC – Stands for GRECY’s Magic for Image Computing. This is a grand-daddy of plugins. It is so packed with various image manipulation tools that I wonder even if someone will discover all of them in lifetime. Right from the basic sharpening, noise reduction to advanced like soft glow. This covers it all. And did I say, each of the tools come with several more options to fine tune the output? Yes, this is one hell of a plugin.

Off-course, there are many more plugins in the GIMP repository but these are the few I use on a regular basis & find to work properly. If you have your favourite GIMP plugin not listed here, do share it below. Will benefit all. :)

Star-trail photographs are mind boggling to look at. Its one of the most beautiful vista of nature. However most of the times when it comes to post-processing the photos after shooting a star trail can be a pain. Here is a small GIMP plugin which will help you elevate all that pain & concentrate more on shooting part of star trails. The plugin is known as ‘gimp-startrail-compositor‘. You can download it here.

Setting the correct exposure is one of the most fundamental of photography. With the inbuilt light meters in our camera’s, this becomes a piece of cake as we no longer need to work by the Sunny 16 or any other gothic rule. However over dependence on these inbuilt meters have meant most of the amateur photographers not able to count exposure mentally in terms of stops.

This ability to increase or decrease the exposure by stops comes in handy when one is trying his/her hand at really long exposures. Once you put a dense enough Neutral Density(ND) filter, you will need to count back in stops so as to determine the correct exposure. Depending on the density of your ND filter, this may demand to count back up-to 10 or more stops. Now if you’re sound of your knowledge about the aperture & shutter-speed scale, then you’ll breeze through. Else you might go for the trial & error method. However, the trial & error method would take sometime before you figure out the correct exposure. Instead, use ‘Exposure Calculator‘.

Exposure Calculator

Exposure Calculator is a nifty android application which allows one to calculate exposure for long exposures. One needs to simply input the current correct exposure settings(indicated by your camera’s inbuilt meter) in the top part of the application after which you input the density of your ND filter in stops & you’ve your new exposure automatically calculated for you at the bottom. Makes sure you input the correct settings in the first place else your exposure will be skewed.

That’s it! Now if maths was not your favourite subject in high school, simply use the ‘Exposure Calculator’ & give all the worries of your calculation to your maths teacher. :)

Photo collage make for a wonderful gift. It makes for a good gift since one can include photographs shot across various time-line of a relation which when looked back brings immense satisfaction. Being a photographer, my friends have been receiving such photo collages from me. To make this collage, I use a nifty piece of software known as “FotoWall”.

Earlier on we had walked through managing software packages under Debian Linux. In this post we look at managing software under an RPM based Linux distro. RPM stands for Red Hat Package Manager. As the name suggest this format was developed by Redhat but now it is not confined to Redhat Linux. Now many Linux distros like OpenSUSE, Mandriva etc have incorporated the RPM format. There are many graphical utilities out there which can help you manage software on your RPM distro but as always command line will offer you total control & flexibility over the process. Let’s go ahead & learn how to manage software on an RPM linux distro. Below foobar refers to an example application. Replace it by the name of your software package.
