Burj Khalifa by Dr Isaac Vaisman, PPSA

April 2018 - Burj Khalifa

About the Image(s)

Burj Khalifa was created last November in Dubai – United Arab Emirates using a Nikon D750 with the Nikkor Lens 20 mm f/1.8, hand held and with these settings: ISO 500, f/14 sec. This still is the tallest structure in the world with 160 stories (You can visit the 148th floor and the view is just incredible and everything looks like a Lego construction from up there). It was a three exposure HDR as follows: 1/200, EV 2.0 - 1/800, EV 0 - 1/3200, EV 3.0. The images were processed using Aurora 2018 HDR and were able to obtain these impressive array of clouds. The vantage point was the best to get the whole building, but unable to prevent the keystoning effect. I tried to correct it in LightRoom but it looks worse, so it stays as is. The image was just cropped slightly.

Really amazing sky in this photo Isaac. It's a very majestic looking picture with a really great view of the towering structures. Really great work on the post-processing! I like the reflections you can see in the building near the bottom levels.   Posted: 04/03/2018 11:45:36

You've done a very good job here to photograph this famous building. I think it's inevitable with something this high that you will end up with perspective distortion, so you might as well not try to correct it (funny how the camera sees it but the eye doesn't). The sky is quite dramatic and is equally as strong as the mian subject, so I tried an increase in contrast (Curves S-shape) to provide more tonal separation. Also, I feel that there is a slight cyan cast on the image so I applied a little colour correction, and then I pulled down the brightness of the sky in the lower left.   Posted: 04/09/2018 04:15:46

Guy, it looks good, but now on my monitor it has a magenta hue. specially the sky. My monitor may need color recalibration....   Posted: 04/09/2018 11:20:37

Looks like a difference in monitor displays between us. I have an Eizo which has a built-in calibrator and I do it every 200 hours (when it reminds me). Maybe others in the group can say what the two images look like to them?   Posted: 04/09/2018 11:46:57
 
On my Macbook Pro laptop, you can see some magenta tint to the clouds but then I move it over to my HP monitor (which is where I do all my post-processing) and I'd say most of the magenta disappears however the sky isn't as blue as it was before.

Someday I'll buy a monitor that shows me true colors for my post-processing but now I'm trying to live with what I have.   Posted: 04/12/2018 16:12:31

I use a top end Samsung monitor which I calibrated 3 days ago and on my monitor there is a slight magenta tint to the sky this just shows how things change from monitor to monitor.

Thabks for all the comments on the colour. I took my version of the image from the website back into Photoshop and analysed four points. These are on the clouds and circled in red. The RGB colours are given alongside. As you can see, there is on all points an overall blue cast with a very small amount of red, which might well look like a magenta tinge. For the clouds to be pure white, all RGB values should be the same. However, a slight blue cast in the clouds seems to be acceptable. My apologies for the tiny amount of red getting through.   Posted: 04/13/2018 06:15:13

No need to apologise this is how we learn from one another I am finding this fascinating.

Really spectacular!!! And you found a terrific sky! And I think it's a delightful foreground. Only thing I don't understand is why you were there.   Posted: 04/09/2018 11:47:04

Hi Isaac
What a sky lucky you were there at this time the HDR has worked a treat the keystoning does not bother me in fact in this image I just think it adds scale and impact to the image I am wondering if I have ever seen an image with so many shades of blue the range is fantastic and they all compliment each other.
An image with impact for me.   Posted: 04/13/2018 05:46:52

Hi Isaac, I corrected the key stoning using Ctrl A Ctrl T to straiten the bldgs. To fix most of the blue cast I used the dehaze slider in camera raw, then color balance in PS Moved cyan R to 31 then yellow L +21. The Bldg. height perspective is different but it works. I don't know how to get the image into Group 4 so I shall send it to you and perhaps you can work your magic so the other members can see the change.   Posted: 04/14/2018 15:26:11
