Its all about nothing / LRK Night-scape
This was taken on almost full-moon-night at LRK starting from late evening up to moon rise to achieve this dramatic light in the frame...
These are some 180 different exposures, stacked together in a single frame... thus u can say its 1 hour 30 minutes exposure...
I would like to know your views and suggestion on this to improve it further...
Best Regards...

Tell me one thing, would this have looked the same if you had taken a single exposure of 1 hr 30 mins ? What is the difference between taking so many shots for 1 hr 30 mins and one single exposure for the same time ? Were there any alterations in the exposure conditions like aperture or time which prompted you to go for so many shots and then stacking them ? I have not done much of landscape, I have very less idea about these kind of images. It is looking nice due to the colors. So I guess at the end of the day, the time you selected for the shots played the role. Star trail images though routine still look so good, with the amazing colors of the sunset sky in Gujarat. this one is looking quite different from the usual one's. I loved another one when a gentleman posted a star trail image with aurora borealis.

Beautiful light and well executed. If this were mine I would loose details on the foreground soil. Thanks for sharing Saurabh.

Thank you Ganeshsir & Nilangandaa for your words on this image...
Long exposure or Star-trial for me is always a confusion :-( , as I can't assume the actual effect of light play. After a long time I have tried Star Trail, and was reading about such images from few months from where I have got the link of star-trail software on internet. And thanks to one of my friends Abhishek who gave me the full version of the software to stack the photos...
Clicking single shot adds lot of noise issues in the image, and while removing it I lost enough details from the image... so I tried photo-stacking for the first time... In most articles photographers mentioned about minimum moonlight and late night exposure, so as part of experiment I decided to execute the exposures just after sun-set & during moon rise... I was totally unaware of such light in the frame when I started the exposure...
in fact many photographers exclude and include different set of exposure frames to achieve desired light, but for me it was quite difficult & I just selected all the frames starting from first to last... may be more practice will help in future... and may be achieving correct light in long exposure is still a big deal for me... :-o)
And I have no idea weather the single exposure would have given the same result or different... But the only reason i have gone for photo-stacking is noise issue... :-)
I would like to know some information or any alternatives of such kind of photographs if some experienced one can comment here...

Thank you once again Nilanjandaa & Ganeshsir
Best Regards...

Nice shot Saurabh. Even I prefer to stacking many individual pictures to taking a single exposure. This is exactly for the same reason you posted. Also its easier on the camera battery, though not on the card as we do end up with a lot of images. You can still stack pictures shot at different points in time (say one one shot in evening to capture the twilight and one at midnight with the stars). All the stacking software does is to add the bright pixels of each frame. So if for example you made two images one in the evening twilight and one at midnight, then the stacking adds all the bright pixels in both the frames. So the end result would be an image with bright ground lit by the evening twilight and stars in the sky with probably some colors of the evening sun. This would result in the brightest pixels of both corresponding images to be represented in the final image.

For a single long exposure image, even though the concept of the brightest pixel showing up on the image still stands true, the image will have a muted and uniform color gradient (if there is any color). This may again be due to noise and noise removal but the images will have a marked difference in the color rendition. For dark images with not much color you may not notice the difference apart from the lack of noise.

I have tried both types of shots and photo stacking always seems to produce a better image when compared to a single exposure.

Beautifully done.. I like the way the colors are moving from the left kissing the gold plated earth and spiraling into the skies to form a lovely circle of star trail. It gives a very dynamic feel to the image imbibing it with life.

Very well made image with beautiful colours. Does it look bit extra sharp or it's just my screen. Thank you for sharing
