Shooting RAW – Basic Post Processing

By | Tips & Tricks | No Comments


The above image was taken in RAW and processed.

Disclaimer: Please see the comment @12-04-2011 16:33:50 in

The advantages of shooting RAW related to this post here are.
1. Adjusting the White Balance
2. Exposure

For the first time I have shot in RAW+Fine JPEG mode as an experiment in April next to my home in Bangalore around 7 am.
Surprised to see Western/Eurasian Marsh Harrier Female in the morning searching for the food around!
Sun was playing hide and seek with me, very low light (Typical Bangalore Morning Light)

The following one is direct from camera Jpeg with the default camera settings like
1. Auto Whit Balance
2. Exposure Compensation -1/3 EV
3. Accidentally set Vivid Picture Control (More Saturation)

Getting even a record shot from the above jpeg is extremely difficult as it lacks everything.

So I have taken the corresponding RAW file and did the basic processing on
1. Exposure Compensation around +1.7 EV
2. White Balance set to Direct Sunlight – 5200K
3. Cropping for better view of the subject

And applied Noise reduction and sharpening in Neat Image which looks as follows.

Atleast now it can be used as a record of this species in our area!

Understanding the Tele/Tele zoom lens

By | Tips & Tricks | No Comments


With “little” understanding of mine, I thought of sharing this about telephoto/telephoto zoom lenses…

Every lens has the following attributes
1. Focal length
2. Minimum focus distance
3. Aperture (Smallest Aperture less light required to capture the picture)
4. Sweet spot (Sharpest @some aperture settings)

Most of the times, lenses performance depends on the above parameters.

The following is some of my explanation of above wrt to 70-300mm f/4.5 to f/5.6 VR.
This lens produces excellent images (Full Frame) when
1. Around minimal focus distance-20 feet when subject is small and 20-40 feet when the subject is bigger.
2. Ultra sharp images when the light is very good/light is on the subject.
3. When light is good and aperture is around f/8

In the above scenario, the images are so sharp that no sharpening in PP is required.

The image quality suffers when the subject is in shade/low light, focus is at infinity etc. In general, lens focusing speed will be reduced in low light and also with larger apertures like F/8, f/11 etc.

Also the bokeh directly depends on the distance of the subject in these cases. When the subject is withing the reach of the lens as said above with less clutter in the BG, most of the lenses produces the best they can (very clean, also one should position themselves accordingly for this).

That is the reason, when shooting subjects at far distances, cropping yields less IQ. So in these scenarios better to use good prime telephoto lenses with good converters to get better pictures as their reach is more.

The above Oriental Magpie Robin image was taken with Nikon D800E camera with Nikon AF-S 600mm VR lens and TC 1.4 II tele-convertor in DX mode.

Some sample shots for the explanation.
1. (Clean Bokeh/clean BG, almost @minimal focus distance with no clutters in BG)
2. (Sharp details, distance within the lens reach)
3. (Small subject and focus at infinity, IQ suffers)

Scenarios change for other lenses like Wide angle lenses (a future topic)

How to get best shots

By | Tips & Tricks | No Comments


To get the best shots, one does not “ALWAYS” require the best camera and lens.
Even a point and shoot cameras (P&S) will produce.

Then what’s the limitation?
Normal cameras (P&S, entry level DSLRs with consumer lenses) have some challenges

1. Low light – Early mornings, late evenings, overcast weather and general indoor shots.
2. Sports/Kids/Action shots – which require fast focusing, speed.

So when shooting with normal cameras following techniques will help in producing better images.

1. Go for photography on sunny days with plenty of light.
2. Subject should not be in a shade, avoid taking such shots (non record shots).
3. Avoid shooting distant subjects then cropping heavily.
4. Shoot within the focus range to preserve more details and contrast.
5. Use appropriate filters in situations when required, like landscape photography, reflected surfaces etc.
6. Follow good techniques to approach the subject without disturbing it much, This results less cropping of the image, gets better IQ and captures more detail.
7. Use appropriate lenses for the appropriate photography (most of us don’t do)! A Macro lens for Macros (more details), Wide angles designed for landscapes. Telephotos/super telephotos for birds (cleaner Background), Medium telephoto lenses for portraits (nicer Bokeh) etc
8. Also similar settings in Cameras until getting proficiency (mostly for P&S) Portrait setting for portraits – Avoids unwanted sharpness on faces Landscape setting for landscapes – Good greens and blues etc.
9. And a standard technique: Keep the Sun behind you, so that your subject will be lit properly in the direct sun light.
10. Keep your tripod/monopod handy, to prevent camera shake at longer focal lengths, in low light for longer shutter speeds (ISO performance of most of these cameras are average).


Nikon DSLRs – Blurring view finder in crop modes

By | Tips & Tricks | No Comments


This tip comes handy while shooting images like above in in-camera crop modes.

I struggled for 2 years to get this info, finally thanks to for posting this.
So posting this for everyone’s benefit who shoots in crop modes (5:4, 1.2X, 1.5X) in Nikon DSLRs like Nikon D800(E)/810 etc.

Go to the Custom Setting Menu and to the setting “a6 AF point illumination” and set it to “OFF”.
This will make it a lot easier to frame subjects by blurring the area outside the cropped frame and making it appear darker.

In some cameras/without latest firmwares like mine, it was “a5″. So please check in Menu “a” for this setting.

Extension Tubes

Tip: Using Extension Tubes

The above image was taken using Extension Tubes.

Saturday, without any prior planning purchased Kenko Extension Tubes (ET) for Nikon F-Mount AF lenses, first time without doing R&D on internet. Tested them for an hour on the night on my AFS 50mm f/1.8G and AFS 70-300mm VR.
Want to share “my thoughts” on them, may be useful for others.

WHY Extension Tubes?
1. To get macro shooting capabilities on non macro lenses.
2. Or to get more magnification than 1:1 on macro lenses

1. Auto focus works on individual ET, not recommended to rely on stacked, and little slow but sufficient for any work.
2. Have to sacrifice shooting at INFINITY, this never worked on any of my lenses tested, so, no birds in flight and no focus on any subject farther than the lens specified maximum focus distance.
3. Should be very careful on focus and DOF. Slight shake of camera will spoil the image.
4. Best results with tripod, where you can use tripod, otherwise shoot as many as you can to make sure you will get enough keepers.

Results on AFS 50mm f/1.8G

1. For medium sized flowers, 12mm ET is a best fit, please check the result posted in the link.

2. For small flowers, 20mm ET will be good.
3. For smallest objects, like 1cm flowers/jewelry like ear rings, 36mm will be the best.

I found the closest focus distance is around 2 inches with this and very much suitable for the above.

Please check this image
Stacking of External Tubes, found not much required as the above are sufficient.

Results on AFS 70-300mm VR
As the zoom lenses are known for their versatility, ETs on this zoom are really versatile and absolute fun using this combination.

1. 12mm ET is not much useful as we will not gain much magnification, but AF is good, can shoot Birds with AF!

Please check the following link.

2. 20mm ET, here the fun starts. When there is no subject in the view finder and you are at 70mm, then start zooming in… Suddenly you will find the subject which means, you lens has acquired focus at that zoom, suppose 200mm, then lock the focus there. Your auto focus works and you can recompose you subject in the same way what normally we do. Manual focus is still not required.

A Butterfly
Another one

And again, you lens is also ready for Bird photography at the same time, check the link below, the subject I was waiting to get a clean shot from last 1.5 years!

This one again with Camera AF, able to shoot around 10 shots without even a single AF failure in absolute low light!!!

3. 36mm ET is good with good AF speed.
Please check this:

Where best suits?
1. Places like parks/gardens for shooting different types of subjects like flowers/butterflies/insects/birds
2. Other places where you may come across such occasions where you may need a macro suddenly like you may go for dedicated bird photography but may find interesting macro subjects.

1. One has to decide in advance what he/she will be shooting, otherwise one has to change the corresponding ETs always.
2. No focus at infinity in my test scenarios
3. Focus must be very accurate and should counter check after the shot
4. Extra added weight
5. Extra investment too!

Definitely one can try ET.
Have a great time and have loads of fun!

Self Assessment

By | Tips & Tricks | No Comments


I feel the easiest way to do the self assessment on our own photo is

1. Open the photo to be judged
2. Browse the same category/same species photos taken by professionals for 10-15 minutes
3. Now go back and see the photo earlier opened!

Definitely everyone will be in a position to judge where their photo stands.
Funny but works.

Focus on Focus – For Beginners

By | Tips & Tricks | No Comments


The first thing people do after buying the new camera is start clicking, with or without focus!
Focus is critical to all the images for both normal and creative photography.

I suggest the below for beginners.

1. Please read the manual first and understand about the focus points/focus area and focus lock behavior of the camera.
2. Switch on the camera and start practicing what was read.
3. Cameras have difficulties in focusing in certain situations like a subject in busy backgrounds, in flight, low light etc. learn more about those situations.
4. Understand your camera focus capabilities in the above situations and use the appropriate settings accordingly.
5. Read and understand Manual Focus and its importance.
6. Few instances are good for Manual focus, so do not use it unless you are completely aware of those situations ex some Macro work.
7. Experiment on focusing in Live View if available and the situations of live view to use ex. sun rise, sun sets etc to avoid hurting eyes.
8. Get the knowledge on subjects to know which areas to be focused like Eyes etc

List grows… So read atleast the minimum and then start taking photos.

Happy Clicking!

Night Photography

By | Tips & Tricks | No Comments


Some interesting ways to capture night shots:

Please see

“Original Light – 1″ corresponds to the lighting available for the shot “With Aperture priority – 1″ – Shot at 8 PM
“Original Light – 2″ corresponds to the lighting available for the shot “Shutter priority – In Camera processed – 2″ – Shot at 11 PM

If shot in aperture priority, shutter will be open till the camera feels the light is sufficient.
In shutter priority, photographer has the luxury to set the amount of time shutter should be open.

I have tested for 30 sec mounting on tripod, triggered the shutter using timer/remote.
One can use BULB mode depending on the requirement.

Settings could be base ISO (ISO 50, 100, 200 etc), Exposure as preferred, Color or B/W on taste, Long exposure noise reduction ON (depending on the DSLR).
