Not HDR, but edited with Snapseed on iPhone...
Nova Scotia on Explorer
Very close! This was a "closed" park by Lake Lavon, Northeast of Dallas and only 15 miles or so from my house. I used three bracketed shots for these, -2, 0, and +2. Combined and edited in Lightroom 4, there is a module called Enfuse that lets you blend the three images and keeps all the RAW data so you can edit how you see fit. Get as crazy or subtle as you want . There are some awesome shots in this thread, HDR is a great way to make everything pop and make us look much cooler than we actually are
Thanks for the tip on Enfuse - I've been merging to HDR from lightroom to photoshop and then back to lightroom. I'll check it out
Interesting, I've been along the western shore of Lavon, and I did not see that little dam. Where is it?
I will add, the last time I was there, I was in my truck, and the short fooled me, I though it was fairly dry, had the truck in 4x2, all of a sudden the rear end started sinking, by the time I caught it and got the truck into 4x4L, it was too late. 1-800-friend-with-a-Z71-HD-1500-chevy time ... :eek1
Oops, the Dam was a part of the DFW tag game and is located in Irving, Sorry forgot about that one.
Have any of you gents played with the effects of depth-of-field on HDR images?
For example shooting your aperature wide open vs. an F8 or F11?
I think I might have to go experiment a little...
[FONT=.Helvetica NeueUI]Hey geek, I actually did the other night taking a pic of this church (3.5f on an 18-135mm lens). DOF wasn't really affected, I just needed the extra light. Didn't have my tripod so I needed as fast a shutter as I could get lol [/FONT]

Experiment: Aperture and HDR.
For any photography geeks I thought I'd post my results... if you couldn't care less please just scan to the next msg
When taking a photo, depth of field is controlled with your Aperture setting.
A low number (big opening) like 1.8 or 2.5 means you get a very shallow depth of field.
A larger number (small opening) like 8.0 or 11.0 means you get a large depth of field.
If you choose a really large number like F22 .. you'll see the dust on your lens
Shooting F1.8 @ 50mm - notice I've focused on the "500XCW" and the depth of field is shallow. The KTM on the tank is blurry (this blur is often referred to as "Bokeh" in photography).
Shooting F11 - notice now the 500xcw AND the KTM are both in focus.
So why do this experiment?
HDR often leads to "super clear" images.
Shooting with a wide open aperture has a purpose of NOT having the entire photo "super clear" but sections of it super clear.
I was curious as to what would happen when the two styles run into eachother
...to be continued.
Some test photos.
I was quick and dirty shooting with a mono-pod so none of these photos are done really well, and the subject isn't that interesting - the goal was to compare the results.
I wrote my own HDR processing script and saved it as a preset in Lightroom 4.1.
Each collection was auto-bracketed by my NEX-7 (-3, 0, +3), opened in Lightroom, merged to HDR in photoshop, and then had my personal preset applied - i.e. the processing of every photo is identical.
The goal wasn't to make remarkable HDR images.. it was to do the exact same thing to the different aperture images of the same item to see what happens.
50mm - F1.8
50mm - F8
50mm - F1.8
50mm - F11
50mm - F1.8
50mm - F11
Depending on your processing style of HDR - the bad things about HDR get exagerated with a shallow depth of field's bokeh regions and the good things about HDR get exagerated in the focal areas.
I think one's particular camera/lens' bokeh quality has a lot to do with it... and the exaggeration that results from merging multiple non-focused elements.
Depending on the boldness of colors, the background can look extra-blotchy from the HDR merge.
Items like straight lines and text that are located in the non-focus area can make the photo look like it was improperly focused due to the HDR sharpen/blend.
Hyper processing cam make a photo look exceptional grainy if large aperture openings are used - so extra care should be taken in the sharpening / smoothing phase of processing.
That's EXACTLY why I was wanting to try this
Shooting in low light I find I need to open the aperture up to get enough light... I wanted to see if HDR processing was going to "get along" with wide open images or a percentage there of...
...because heaven knows HDR does NOT like ISO noise
I've had photography on my brain lately, so that leads to late nights of looking stuff up.
realative to the topic: has anyone tried this app out? https://triggertrap.com/products/triggertrap-mobile/
I guess it can act as an intervalometer. I also see it has a setting for setting up your HDR shots/stops, which is why i'm bringing it up.
They have something listed as hdr time lapse as well, was just curious. The app is free, but the dongle is not.
I have no affiliation with this app, I actually have no affiliation with anything i will ever post on this forum...i'm a roofer
Just looked - not NEX-7 compatible
@Geek, cool test idea. I'm a photo geek too and have always been somewhat fascinated by HDR.
It's something that is usually overdone. I know I went overboard with it when I first dicovered it, and now try to tone it back.
I think a thin DOF inage looks okay with HDR if it's a typical object in focus on a blurred background. Whenever theres forground AND background bokeh, it gets a little messy. Also seems to work better on wide shots, usually landscapes or shots that have a lot to show, not as much on detail shots or close ups.That may be a false generalization, but it seems to sum up my opinion on what i've seen.
The idea of HDR is being able to see more dynamic range in a given scene than you can with a single exposure. That being siad, it lends itslef to certain kinds of shots more than others. Shallow DOF shots often get a lot of their impact from NOT having a whole lot of dynamic range.
Cheers to another geek.
You did that with no tripod???

Two firsts today. HDR with a bike involved and first day competing at Trials.
All Iphone apps, with no computer editing.
Still trying to work out which of two I'm using is better, Pro HDR, or True HDR. finding they take turns at which gives the better result.
I live 5 blocks from Grand Central Station so I figured I could not find a better backdrop for my new 2007 R1200GS. Coocase S50 mounted on the back.
