Today, I tried something which I usually don’t .

Regular flower macros but I spun them a lil in post processing.

Geotagging Images

Posted in Image Processing on February 9th, 2009 by Krishnan V – 11 Comments

I just got back from a trip to Manas & Kaziranga National Parks. One of the things I wanted to try was “Geotagging“. Geotagging helps to write the exact location where the pic was shot, into the EXIF of the pic itself. The software also creates a “.kml” file which will help view the route along with, the exact point on the track where the particular photograph was taken.

I took along a Garmin Etrex Legend GPS and also this is where it gets more interesting, a Nokia 5800 Expressmusic along with a Nokia LD-4W bluetooth GPS. Although the Nokia 5800 Expressmusic has a built in GPS, I took along an external GPS since that is so much more flexible for my application. Besides, the Nokia LD-4W is only a few tens of grams in weight and, smaller than a credit card :-) . So its hardly any trouble carrying it.

I set the Garmin to “Log Track mode”. For the Nokia, here is what I did. Since the Nokia application, “Sportstracker” was at that time not available for the Nokia 5800 (Sportstracker for 5800 EM) , I downloaded another software called @Trip v1.01 . This is a simple phone app that creates a log of the GPS track and writes to a file. You can also use similar apps like GPSED. It will also geotag pics clicked by that phone. Besides you can use the bluetooth GPS + gps app on any non-gps phone.

Capture NX NR & Sharpening settings that I use

Posted in Image Processing on February 13th, 2008 by Krishnan V – Be the first to comment

I use RAW exclusively.

1. Set view to 100% then,  turn OFF Sharpening in the Base Adjustment.

2. Base Adjustment> Camera Adjustments> Sharpening set to NONE.

3. Base Adjustment> Detail Adjustments> Noise Reduction > Intensity & Sharpness set to “0″

Noise Reduction – NR ( Works pretty good for High ISO NR as well )

4. Add New Step> Select Adjustment> Noise Reduction > Intensity – As desired [usually under 5] , Sharpness Set to “0″ , Method Set to Better Quality.

Note: If you want to Paint IN” NR then, dont click OK but, move the window to a side and apply “+” Brush. After you finish Painting in NR, now Click OK. If you would like to Wipe off the NR, Click OK and then use the “-” Brush.

5. Opacity > Blend Mode Normal > adjust opacity as desired.

6. Sharpening: ( Works Great for High ISO especially)

7. Add New Step> Select Adjustment> Focus> High Pass. Use a low value where only the outlines just begins to show.

8. Opacity > Blend Mode set to Overlay then, Luminance & Chrominance > adjust opacity of Luminance & Chrominance as desired. Usually only Luminance Opacity start from 50% and increase till desired. Chrominance set to 100% Opacity.
