I usually first process a single exposure to make sure that I really need to use more than one to get an acceptable result. In this case, in spite of the tough lighting situation, the single exposure I took before taking the HDR sequence actually didn't have any areas hitting the exposure limits. In Lightroom, adjusting the exposure and contrast you can get all the image inside the histogram.

The HDR images the exposure adjustment ranges from -10 to +10. In the non-HDR case the range is -5 to +5. I think in the HDR version I was seeing info between +/- 7, otherwise all black or all white. So gained a couple of stops of range for control, but in this particular case it may not have mattered since nothing was actually blown out.

On HDR file sizes: Looking at an old HDR 32 bit tiff built using the prior method, they were typically getting close to 250MB. These new 32 bit DNGs are under 75MB. Major improvement there.

I was often getting bogged down before in the process of creating composite files, and then dealing with artifacts introduced during the process. That really slow me down. And ultimately I just wasn't happy with the Photoshop 32-bit HDR tone mapping. I think I can get past that roadblock now. What a relief!

Glad I am retired. I have a lot of photo processing to do!!!

Audrey - I like your most recent photo more than the HDR in your previous post. Great image. How did you process the most recent pic (....single_exposure.jpg)?

Well - I was working on the big HD screen workstation, and I took a little more care. Having stared at the image for a while I knew better what it needed.

In the first case I was working on my little Macbook Air laptop with teeny uncalibrated screen. There I was just making sure everything was functional on the laptop and to get an idea of how slow things might be.

Thanks Audrey - I know how that goes. I only download and rough process on my macbook when I'm on the road. Then fine tune later on the bigger monitor when I get home. It does make a big difference.

Another quick and dirty experiment. I did a pano in LR6 from three shots of the Salz River. This is the view of Salzburg from the Monchsberg ridge next to old town. The river does a gentle S curve through the city. I uploaded a 2500 pixel wide jpg (original is around 8700 pixels wide). OK - it looks like this forum set it to 1600 pixels which you have to keep clicking to zoom in all the way.

There is an incredible amount of detail. In the original you can see all the cars and buses. The pedestrians walking across the bridges and down all the streets. You can even see the locks attached to the bridge railings. Amazing!

The initial panorama merge to preview was really, really fast - surprising me. I could switch between the different methods and it didn't take that long. I selected auto crop. Then when I accepted the preview settings LR did the processing, but really didn't take that long. I was expecting a much slower response based on comments I had read. I'm running on my Macbook Air again.

What a delight to be able to go back and adjust the crop after making some small leveling adjustments.

I think they have made some performance improvements, because some of the things I was tinkering with used to crawl in Photoshop, let alone Lightroom.

I spent a lot more time scrolling through this at 100%, looking for artifacts. Didn't find any - just a spot to remove and a distracting white tag to clone over.

The three original shots are around 20MB each. The pano is 103MB

Terrific!

I do wonder, however, about the date in the lower right. It implies the "Date Taken" but I suspect it was the date of processing. <grin>

Do you have faith in DNG to store a lot of your photos under that format?

Well for HDRs and Panos, better than JPGs or TIFFs at any rate?

Heard some people rave about Polar, an online-only editor.

Yes. It's better than a company proprietary camera raw format.
Way better than JPGS - it has all the data.

Not too worried about the Adobe formats for the next few decades anyway.

TIFFs are just huge.

Up until now I had been using PSD files.

I didn't put that date there, the forum did. That looks like an upload timestamp. If you click on the image to open it directly, that will go away. Then click again, and you can zoom in more on the image at 1600 pixels.

Funny that when I did that earlier it simply closed the image. I did wonder (it worked correctly this time).

In any event, it is a wonderful picture... but, you know me, it should be hanging on a wall and not viewed on a monitor smaller than 40". <chuckle>

Adobe won't go away but I wonder how long DNG will prove to be useful.

I can't imagine converting all the NEFs I have to DNGs.

Thanks much to whoever mentioned the new LR6 capabilities, because I wasn't really paying attention. This is just in time for my next big Europe trip and I'm very excited about taking this easy to use composite capability on the road with me!

I just see it as a non-proprietary camera raw format. I don't see why it wouldn't continue to be useful as long as Adobe is around.

My plan is to convert my NEFs and CR2 raw files to DNG only once I start having problems reading them in photo software. Hopefully that day never happens.

However, I'm happy to use DNGs for the processed HDR and panoramas.

I always keep a copy of my original camera raw file (Canon).

Since I started using Lightroom (4?) I made a DNG copy when importing selected photos. So my photos chosen for processing are in that format. That covers the last 3 years or 4 years of photos.

My older photos are in Canon Camera Raw format.

I think that even if Adobe does go away, that since DNG is open source there will be a reader for it for the foreseeable future.

(Although I have yet to use DNG.)
