Optical Slave Triggers – a piece of accessory which is tremendously useful if you work with strobes/speedlights. These are tiny in size but can help you accomplish wonderful photographs. It simply is a light sensitive sensor within which senses the light and triggers the circuit which then ultimately triggers the attached strobe or speedlight.

Ganesh Chaturthi has begun & it’s already in the third day. The city is painted with the fervor as the elephant headed lord makes his stay in homes of the devotees. Yesterday, some bid adieu to their lord at the completion of 1.5 days. The chowpatty painted colored scenes. Here is a glimpse through my lens.
An important aspect of photography is ‘timing’. Often a millisecond separates a snapshot from an award winning shot. Timing comes only from proper judgment and foresight of the situation. A photographer should be patient & calm as he shoots.

Altering a process priority is indispensable when you wish to change the behaviour of a running program on the system. Most of the times, when one wants a program to complete its processing faster, tuning its priority holds the key.
Under Linux, this can be accomplished by two ways – GUI & CLI. For this article, we will look at changing a process priority the GUI way. The CLI warrants a separate article.
Once you have the process running, simply open the “System Monitor”. Do note, I am under KDE for this demonstration. So the system monitor options may vary as per your desktop environment. However, the corresponding options should be self explanatory.
Once in System Monitor, click on the “Process Table” tab for a summary of running processes on the system. Here identify your program. In my case, I wished to increase the priority of the Openshot process so it may process my video faster. So upon highlighting the Openshot Video Editor’s process in the table, I hit F8.You should now notice a similar window like one shown above. Here drag the sliders to the right for faster processing. You will be prompted for the root password as you do so. That’s all, the process should now conclude faster.
