Exactly.

It has been raining everyday here, but I am too busy to click. I hope others have made use of the rain and have some fresh photos.

Samurai, There is a blue cast in this image. Or is it my monitor?

Thanks

I can't make out, but then my eyes aren't that good.

Sure, go ahead. That's a old PP anyway.

Thanks Samurai.

Here is your version (Which i thought had Blue cast)

And here is the one i color corrected (There are still rooms for improvement but just did a basic correction here)


Let me know what you think

Thanks

Oh, now I know what you mean. Actually I may have added that blue cast while experimenting with PS. I'll check the ORF file when I get home.

Could be, mostly it happens due to screwed up metering caused by weird lighting conditions. When u do levels adjustments, just don't slide the bars where hologram is starting, but also do a color balance layer if u think u have some color cast.

Liked that inverted first image. Interesting viewpoint.

*cough*cough* - where have i seen this before?

BTW, since we are on the topic - TG. I loved the sunroof + rain image of yours.

We've had one of these "what makes a good photo" discussions in the auto/non-auto image thread before and one of my likes was - "finding an image interesting and continuing to look at it because i can't quite figure out exactly what it is, or how it was shot".

The "sunroof" wasn't a sunroof to me until you mentioned it, and it looked way too luminous to be a car body -- i kept thinking it was taken in some sort of glass shower cubicle, but i couldn't figure it out! Nice one.

Thanks Rehaan. The photograph was clicked from inside the car (Skoda Laura & I almost broke the gear rod) and I had to do some gymnastic tricks to click that with my 18-55mm lens!

Theme Ends on 15th October 2009


From today we will kickstart the new theme
Long Exposure on a tripod.

Typically, exposures of few seconds or longer qualify as long exposures.
Handheld high ISO shots do not qualify as long exposure, so for such shots, you definitely need a tripod.

Many P&S cams take exposures upto 10 seconds, and some Panny models can go upto 60 seconds in Starry sky mode.
For DSLRs(most) there is no limitation.
Without a shutter release(remote) you can take exposures upto 30 seconds, and with a remote in bulb mode you can go upto as long as your battery lasts.

To Kickstart the theme, I will post a couple of pics.
Note, these are very very long exposures

First - Pangong Tso.
Technical details
142s
F4.5
ISO 200
18mm


Second, Hanle Gamma Ray array. The moon is behind the clouds, so unnatural light. Infact long exposures of windy night skies often yield very dramatic shots
589S
F6.3
ISO 200
18mm

Some tips

• Use a tripod, handheld, you will always get blurry shots, not matter how steady your hand. Over 1/6th of a second or so, even image stabilization does not work. Shots with 1/6th of a second etc., are not long exposure
• When camera is on tripod switch of image stabilization. Some lenses and cameras can detect tripods, but this is not always the case
• Use an ISO closer to lower number. For example if you have a DSLR capable of ISO 100-3200, take shots at ISO 100 or 200 because noise is more at higher ISO's and noise can ruin a shot. If you have a P&S camera, stick to lowest ISO, for example ISO 80
• If you want to get stars, use a wider aperture, otherwise stars will be faint. But that will also mean you would need to frame the shot so that you can focus near infinity, and the nearest part of your frame is few meters away. At wide angle, even when lens is full open you can get everything from few meters to infinity in focus
• Hot sensor means more noise. So unless you are shooting in environments where ambient temp is below 10 degree C, take a few minutes break between shots to allow sensor to cool down
• The easiest long exposure shots are cityscapes where even a 5 second exposure can yield you bright shots
• If you are shooting a dark moonlit landscape at night, sometimes even 30 seconds yields a dark shot. So if there is a full moon, try ISO 400 at max aperture. Without the moon, or even when moon is half even 100s can be less
• Long exposure shots of waterfalls rivers yield silky water

Happy shooting fellas. Remember, stick to the rules, do not post handheld shots less than 2-3 seconds. 5 seconds + preferred.

And last but not the least, with a Neutral density filter, you can actually take long exposures even in the evening, for example, this shot
Exposure = 6s
Aperture f/8.0
18mm
ISO 100

It was taken late evening with a tripod.

Damn!!! 142 secs you can actually see the earth rotating (causing the stars to look like they were moving).

Just got a Canon 1000 D, will start contributing once i get a hang of all the features.
