The image looks blown up...the wide color gamut has not been captured. You may need to tone map it better. I would say, the composition is not great, so the HDR effect is anyway being nullified. I was an HDR freak before, these days not much...I guess i am over it now, thanks to the forum . HDR is nice, but exposure blending is even better as it results in a much realistic render. HDR , when done artistically can yield some spectacular surreal results as well.

In the above shot, both HDR quality and photographic composition is missing. Nevertheless I understand that it is a trial shot, nice try. Keep them coming. All the best.

A couple of old HDRs from my Sony H50 Point and Shoot.

I beg pardon to every poster here. I doubt if I am wasting everyone's time here. People come to this thread only to post or view amazing images, not for an elaborate discussion on post-processing. Sorry folks. May be I have to move to the photoshop thread if required. The only reason for me to post here was by expecting a simple solution to it, but it doesnt look like a simple one anymore. Thanks !
In Photoshop, you can try the transforms.

Copy your image from the background layer to a new layer (Ctrl+J in windows). Then goto Edit-> Transform->Skew.

Now it enters the skew mode wherein you can manually drag the bottom edges of the layer to compress the image from the bottom a bit. When you're done, press Enter.

I hope this can correct the distortion a bit. You may try other transforms like Scale, perspective and Distort as well.

I used to corrent perpective distortion via Huginm but unless you are shooting very tall buildings, it takes the zing out of arcitechture shots

Main aim for this HDR was to get a natural looking shot (rather than to create an artistic looking image) when it was not possible by normal processes.

The view from my balcony looked exactly how it appears in the image. I know the subject isn't good, but I wanted to try .

Yes thats what majority do. Distortion comes to an advantage anything other than architect. Its not sena vihar. Its RMV Clusters, Bangalore North. You will hear every language of our country within its premises, so far I counted around 14 (over 200 families) ! As a rule of the universe, we have around 8 Mallu familes too. You want to know 'who scratched where'? ask a mallu.

By the way, your photo of those rocks and clouds, I was mesmerized bigtime. You stare at it for 10 seconds, you will feel like you are on an express-highway and the rocks will look like fast moving cars and trucks ! How do you do this ?

I tried few things, but the picture gets distorted bigtime. Now the complete lot is given to a professional. We thought of using them in a website, if I post it as it is, people in that block will either eat me alive or shift from there.

Shaju,

Another thing you could try is step back and take the picture. The edges of the frame would be skewed, but you can crop it to get the similar picture as in your previous photo minus the distortion. That's where more megapixels help.

EDIT: You could also step back, zoom in to get the same frame as your previous shot. Both the methods stated might work, but there will be changes in perspective.

Here is the outcome -
Attachment 159983

The 3 images used to create this HDR can be viewed at - Picasa Web Albums - Ronak Gandhi - HDR attempt

Let me know you views.
Gandhi: Instead of spacing out the exposures by two steps (+2, -2), you could try taking 4 shots with just 1 f-stop between them. this would produce a better HDR than the current one.

When I initially started taking HDRs, the biggestt blunder I used to do was to take shots which are too much spaced out in f-stops. Later, I realized that taking few shots which are just 1 f stops from each other would actually improve the HDR quality. The rule of thumb is, the individual shots do not need to visually differ too much in terms of exposure.

Thanks buddy, I will try that this weekend. If that can save time on playing around with the previous lot of photos, defenitely its worth trying. Clicking another set of photos is easier than clicking on the mouse a 100 times !

If that's the case, you are your best judge! I understood you wanted to try, hence I mentioned you the very best. Well, to my eye, the shot is missing the Dynamic Range. Realistic or surrealistic, both ways.

@clevermax
Yes. Completely agree with that.

@Shajufx
Well, I didnt quite understand your question!

TG.

Do you really really want pictures of some buildings that may not interest to anyone here ? I will go out this weekend and try something new for you. Atleast I dont get thrown out of this thread by die-hard DSLR guys

I was appreciating your work, not asking a question. If you got confused with my question "How do you do that?", that was an exclamation! Sometimes I feel whatever you click in your place comes out good. Is it because you are in the States ? Bangalore we sadly miss a beach !!

Point noted. Haven't been able to try more HDRs off late, so no progress yet.

Will try the next time I try my hands at HDR. Thanks.
