Well folks it has been a great run for a faithful UHH member of this thread of challenges that started out as "photo a day" challenge started by "photogrl57" on 1/1/2012. I first posted on day 46 of that thread on 2/15/2012. After some deep diving, and meticulous research in RR's profile through 1,734 pages detailing 25,999 post I found that Roadrunner'€™s first post was on 10/22/2011. I had been lurking on the UHH site at about the same time, and played around with a welcoming post some times. On January 1st, 2012 Roadrunner was right there, along with a number of others that have helped the thread continue to its present course. After a couple of iterations we are here now with two subjects a week (M,T,W and T,F, and S) and then Free Sunday. Jim volunteered to host the Free Sunday for as long as we could stand him and hosted his first one January 5th, 2014.

We have stood you well Jim and you've left some big shoes to fill, but I've got some Velcro straps and garter clips to help keep them on until I can grow into them. May need some help once in a while if I fall out of them. At my age that could happen. There is a lot of thanks to be given for your dedication to this thread Jim. I’m sure all have enjoyed your participation and will raise a glass with me to toast you. Thank you.

Rolk and Clicker, your "expressions" and "spring has sprung" challenges were fantastic last week. Great participation. So now it'€™s free Sunday and this is where you can drop off any of your left overs from last weeks challenges or throw anything else up on the posts that you think will excite us or that you're just a little bit proud of, or something you're not so proud of and you want to teach us something from your lesson learned. And in maintaining Jim's program there will be no charge! It is still a "FREE SUNDAY"

I wanted to share a little tutorial about eliminating camera noise at high ISO using Focus Stacking
I use Lightroom Classic & Photoshop CC 2018. This only works on stationary images and maybe portrait photos, but that's another experiment for another day.
I have four photos, first one was shot at ISO 6400, low light. Don't look at the mess. Everything here is stationary. This could be a cityscape, landscape or indoors where it's late very low light and the only way to shot would be a very long shutter speed or raise the ISO.
Please use the download feature to see the noise.
Second photo is a blown up area of showing the camera noise at ISO 6400.
Third photo is the same area after focus staking showing very little noise.
And finally the forth is the final produce full size to compare with photo one.

Setup your camera for proper exposure. For this experiment I took 14 shots. A shutter release really helps but not necessary. You can do this with a lot less photos but the more shots the better the results. Download all the images to your computer.

1. Open Photoshop. Open File-Scripts and select Load Files into Stack. (photo 5)

2. In the Load Layers Box, Select Browse and select all the photos and press open.
Note: This will work on all files including RAW (photo 6)

3. Check the "Attempt to Automatically Align Source Images"
click "OK". This will load each photo into a separate layer and align. (photo 7)

4. Select the top layer, Scroll down to the bottom layer, hold the "shift" key down and click on the bottom layer.
You should now have all the layers highlighted. (photo 8)

5. Open Layer-Smart Objects and select "Convert to Smart Object". you should now have one layer that is a smart object. (photo 9)

6. Here's where the magic happens.
Open Layer-Smart Objects-Stack Mode and select "Median" (photo 10)

That it. Simple. Hope this makes since. Any Questions either PM me or ask here. I'll be glad to help.

Larry, there is no doubt in my mind that you will do a
wonderful job on this challenge.

I also want to give a huge "Thank You" to Jim not only
for running "FREE SUNDAYS" for so many years, but
for everything he contributes to UHH!

That said, I like to "play" with images...hope you enjoy.
