Post-Processing PP Challenge 139 - San Diego Reflections!

I decided to try and keep the feeling of night but also recover some details. I started with two versions of the raw -- one that recovered detail evenly and then one that blew out the city in exchange of getting nice clouds.I removed the city and sidewalk and other lights and kept the clouds, tree, and water. This allowed me to blend it in with a linear burn and, I think, 31% opacity to recover sky detail. Then i copied the background, the whole image layer, changed the blending to luminosity, and made the now-middle layer black and white. Using the sliders, I made the light sources the proper, I felt, tone and brightness. Then i flattened it all.

Then I balanced out the hues a bit to make a more-uniform color scheme image-wide, including correcting the sidewalk for white. I left a bit of orange there to give the image some warmth. I duplicated the layer twice and blended both new layers as overlay. One I ran a high pass at 12 over, which made the lights in the city and tree leaves pop but left most of the rest of the image alone. The other I left as-was and changed the opacity to 4%, which tweaked the lighting slightly.

All that left a dark halo around the primary street light. On the bottom layer, I used a 20% dodge for shadow areas to dodge out the halo the best that I could. I flattened the image and voila!

My thoughts are that you used a vignette removal tool then did clarify or sharpening or HDR and it enhanced the gradual changes from light to dark. Try doing vignette removal last, see if that helps

I must say, I am quite proud of this one - captured it last night.

Are motor sports OK? A demolition derby I saw on Saturday as part of the entertainment program at a local agricultural show. Many of the drivers were women.

Ambient light was very poor - about 1 LV out on the track if I was lucky. Sigma 70-200 HSM II. Most shots ISO 8000 and above, f2.8, 1/80-1/200 sec.

Weather Sealed?

I am that soldier. I can assure you that it isn't a "novelty one-time demonstration." That was actually the second iteration I did that day (I screwed up the first shoot), and now, 1 month later, I have never had a single issue with either camera. No sand inside any of the dials, buttons, etc. The flash got "stuck" on the K-7 in the video because sand had gotten under it (it is weather sealed also, but not the space between it and the camera), so once I raised it up manually, it was good to go, and today it feels as if I just bought it - springy as ever. Come winter time I plan to do a sequal to that weather sealing video - I'll save the details to keep it a surprise ;)

Also, you have to remember, that natural rain hardly ever has the same intensity and pressure as a full blown shower head - I have lived through plenty of hurricanes and I can promise you that whatever rain you are thinking of will at best match the water's intensity that you saw in that video I made. And that would be unbelievably rare when it does happen.

In my opinion, by calling what happened in that video a gimmick and a novelty is being very shortsighted and unappreciative of just how traumatic and demanding that test was, as well as how much more severe that would be compared to actual, real-life situations.

For those that haven't seen the video the OP and I are referencing, here it is:

Similar to one I posted a while back, but this time with a twist. I've been wanting to try this for a while, and finally had the chance recently!

What would be the best way to capture Venus in front of the sun next month?

You'll need a telescope with a camera mount and of course a solar filter for the telescope.
This transit is not something you will see with your kit lens pointed at the sun; the transit will be a little black speck in front of the sun. You'll need a very long focal length (hence the telescope with a camera mount) and unless you want to fry your sensor and your retina, make sure you use the proper solar filter (for example Celestron Solar Filter (CPC1100, CGE 1100 )) to avoid serious eye and camera damage. I can't urge you enough to make sure you shield your eyes and camera sensor by using the proper filters, DON'T try DIY solar filters.
