HDR Panorama

We were talking about two concepts one was hdr where weaken combined more than one exposure into a single image and the others panorama one combine the two concepts together we could do hdr panoramas in the end result is a raw file which means we don't have to start thinking about adjusting the image until we're done with doing all the stitching and everything but we have to think through how exactly would you do this and how would you do it effectively so let's talk about it so first let's look at serious of exposures and here I have an image that I shot in, uh gone and, uh I never can pronounce it correctly. Miramar burma uh and if you look at this one in order to get shattered detail in the image this is how bright the image ended up being. But if you look at the sky there's nothing there for the most part so not only did I take this shot, I took one two stops darker and if it wanted to get even more around that where the sun is, which high position right in this area I took another...

one two stops darker so I can get a nice detail all the way down to really close to the edge of the sun so I did that, but I didn't just take those three shots I then moved my camera over, and I took three more. And then I moved my camera over, and I took three more. My camera over it just kept doing that until I captured this full expands of this area. So now, how can I take those images that I captured in macon hdr panorama? Well, you first need to remember that if I select three of these images, there was a keyboard shortcut to merge them into an hdr. And that was photo photo merge. And there it is, hdr. Remember, it was control h and if you add the shift key, you could do it behind the scenes, right? So the first thing I would do is do shift control h then I would select the next three images shift, control each, and then select the next three images shift control each. And I would keep doing that until I got all of these images that make sense. And if I go up here, you would see that there's two or three or four five, or in this case, maybe eight images being merged, all in the background. Now, the end result of that, we're going to be some dmg files, because that's, the file format we get as a result of merging those into hd ours now that's going toe cause this folder to start looking like it's very cluttered with images, because not only will I have the original exposures, but I'm also going to have additional images that are the d n g versions. So what I can do is at the top of my screen there's this bar called the filter bar, and up there I can limit which images some viewing. So if I go over here in tap on the choice called meta data, then I have these various columns here where I can choose to onley view images that conform to whatever kind of search I want to apply. If you click on a heading of eating one of these columns, you can tell what kind of information would you like to search for? I'm going to search for file type because I don't want to see my original brought files. I want to see the dmg files, those air called digital negatives, and if I were a click right here now, instead of viewing every single picture that was in that folder, I'd be on ly viewing the images that aaron dmg format and that's the form that we get as the result of doing the merging into hdr, therefore no longer going to see the original exposures, and it won't look a cluttered now here I only have two of them because that's what I used the keyboard shortcut on I didn't want you guys to have to wait until every single one of those was done, so what I'll do is go to a different folder where I've already merged them together these air all dmg files this would be the result of waiting for the progress part of finish on every single image that was on that folder, then these d ngs I'm in a select and I'm going to just go over here and say now make him a panorama and I could have even used the keyboard shortcut for it if I knew I had the settings I liked and all I need to do when this is done it's hit the merge button and it will merge them together and just so we don't have to wait I think I have the end result already because this will take a bit of time we're getting more and more data in this file and it's going to be just more for to think about the process is no different than the other panoramas we did though, so let me see if I can find nn resolved have a folder it has it all okay here's my in resolve this is an hdr panorama and so if you look at the amount of detail we have in the sky right up against the sun right here we would usually have nowhere near that much that son would have blown out the sky quite a bit out here as you saw when I have the exposures where you could easily see the detail that was here the sky was pretty much white in this large area but by doing hdr capturing more than one image going across here first I end up merging the individual sequences of exposures for the left side of the panorama hdr the middle of of it as hdr the right is hdr end up with all these separate hbr files take those resulting hd ours and emerged them is panorama then I go to the developed module in in the developed module, I optimized the image this has already been optimized. If I hit reset, you would see what it would look like before moving the sliders around a reset or to adjust it and again, usually I bring the shadows all the way up the highlights all the way down, and then I just exposure to get the overall brightness the way I like it. Once I've done that, then I adjust it like any other picture I've ever had meaning use the rest of the sliders just as he would with any other image and I think it's great being able to do an hdr panorama where the end result is a raw file, which means the quality is the same adjusting the image right now compared to having pre adjusted everything in older software like abuse photoshopped to do this or use votomatics to do this or hdr fx pro is another popular program the end result is not a raw file and that means that it's important you pre adjust all those images to get this much quality out of those images that you can before you start merging them together and it's really difficult to figure out what adjustments settings you need to use before you see it as a full panorama when your view it is just the individual files it's really hard to figure out what adjustment to use, and so I find this to be a vastly superior way of thinking on occasion this won't do a good job, it just won't stitch well and when that's the case, I need to fall back on using either photo shop to do the stitching or using photo matics or something else. But I'm not going to have the same versatility, and so if you want to see other examples here's a pretty wild hdr panorama um the location that would otherwise be really difficult to capture if you think about it you're looking right outside where you have an extremely bright area out here and this is usually much more shady, but we got the detail everywhere we have the full panorama now is there a question here a bit off topic but when you were looking at the metadata filter is there a way to change the default settings for what those are across the top by for example camera only use one camera I would like to change that to a different filter it's usually going to remember what you used last so when I go to many data you notice it still says file type on the left because that's what I used last and you got to be careful because it will remember what you last clicked on like here were limited it to dmg negatives I switched to a different folder thing and it can remember that but if you want to set this up to various things like for instance I like file type here then over here I don't like camera I don't usually use that instead I like having the next section b developed preset because then I can see which ones are at default settings versus having been adjusted then I like having over here the either the rating or something else but once you set this up the way you like it go to the far right it'll take me a moment to find it right here so what I did is there's this little lock symbol the lock symbol means that if it's unlocked if I switch folders that I'm viewing reset this where no longer filtering to onley show whatever it was set up to, if you click the lock symbol, it means keep it consistent. Even when I switched between folders, still filter it toe on ly shou. Whatever I was filtering before, but right next to that is a little poppet menu, and if I choose it, it says right here, safe current settings is new preset. They give it a name. And if you look in here, one of the choices I have is ben's default, and it is easy to find processed. And if I choose that, it might change what is being displayed up here. So now I'm seeing file type, develop, reset date in lens. That might be my choice. So set up multiple ones of these so you can very quickly kind of re populated with other settings. A couple things about the panorama. There are some limitations, and one of the limitations is there is a maximum size because light room has the magic maximum size of how big of a file it can deal with. In the maximum file is sixty four thousand pixels on the widest dimension of your panorama or five hundred twelve. Uh, megapixels or megabytes. I don't remember, but there is a limitation. And so there will be some panorama is if you have a really huge ones where you went three hundred sixty degrees around and have a really high resolution camera, the light room might not be able to handle he, and so just so you're aware of that, um, and I haven't run into that much because, you know, most the time I don't have sixty four thousand pixels, that's, that's, pretty huge, you can still send it over to photo shop, and it could most likely handle some larger than them. When you're done, though, you have to scale it down in order for light room, be able tio deal with that file, then before we go on to something other than talking about the library in the developed module, one other change they made you might want to think about, and that is we've had it before, where, when you're in the library module on the right side of your screen, there's this area called quick develop and what I mentioned it briefly, because there's a change they've made there, and if you happen to use quick develop, you want to know about it so there's two different places where we can adjust our images one is to go into the developed module, where you see the list of sliders we can entrust our pictures with and whenever we move those sliders, if you have more than one picture selected let's say I had all these images here selected. I hit the letter d to go to the developed module at the bottom of the developed module is a choice here called auto sink. If auto sink has turned off with this little light switch, then when I end up moving these sliders it's only going to affect this one image that I'm looking at, even though I had more than one image selected at the time, I went to the developed module. If I turn auto sink on by clicking on this little guy now, any change that I make to the slaughters will affect all of the images that I currently have selected and automatically keeps them in sync. But when I do that let's say that I had images where my exposure slider was set differently for each image because they very, you know, I looked at these particular images life I just them one at a time in a look at this image is pretty darn bright. So maybe I have my exposure setting turned down. Then I'll use the arrow keys to switch to my next image. This one is not as bright, so I moved the exposure slider less. This one here is maybe even too dark, so I move in the opposite direction. I might have different exposure settings now the problem is if I select all those images again and I go back to my develop module if I make a change to exposure right now, it's going to bring them all to the exact same setting to wherever I end up with exposure. So when you're in the developed module, you have auto sync turned on the moment you move one of these sliders, all of those images get to go to the exact same setting for the slaughter you've used. But when I'm here in the library module and I used these, the thing called quick develop its different these air what's known as relative adjustments, which means that if I covered over here to exposure and I hit this little arrow to the right to say, increase the exposure or brighten the pictures, what it means is do it relative to what's already been applied to the image. So if one image has exposure set at its default it's going to get boosted a little bit if another image has the exposure slip setting turned way up is still going to get boosted, but on lee a little bit it's not going to bring them all to the same setting it's going to move them all relative to where they were a certain amount and so that could be an advantage here if you find out that you have all these images and the client says they're all too dark even though you've already optimized each one individually, mccline says hey these air just too dark you usually have to go into every single one and adjust them individually if he went to the develop module because each one most likely had different settings but if you do it here under quick develop, it'll just say hey let's, starting from whatever settings we currently have let's just increase them all or decrease them all let's not put them all in the exact same setting that's not new that's just the way it works what's different here is that a newest version? If you come in here and hold your your mouse over these without clicking, it would tell you by how much it would change those settings and some people found these to be too high. One stop is too great of a change one third of thought for some people was too great of a change so what's new is if you hold it shifty, you'll get half a cz much changes usual so even though if you might hover over this and it says it would give you one stop if you have the shift key held down and you click on it, you're going to instead get a half a stop and so therefore you can make him or, you know, slight change to your image so if you use quick develop in the past and it's something you rely on and you just find it's too great of a change sometimes add shift you'll be making a smaller change yes back great talking with the sink and auto sink I'm a little bit confused if you, uh, say highlight three pictures, I'm doing the exact same lens correction in all three of them? Yes, if he had ought to think it applies it all of them board if it sank, it applies it all of them uh, let's talk about that let's go in here so auto sink means if I move a slider right now move that slider on all the images it doesn't look at the sliders I moved in the past, like yesterday or two weeks ago. It means right now if I grab a slaughter and move it, move on, lee, that particular slider on all the images that are selected now, if I forgot to have auto sync turned on and I just didn't realize it wasn't turned on, I still have, you know, three or five or however many images selected, I move these sliders around that would be on lee this one image revealing gets changed cusato six turned off so then instead I could sink it, see the sync button if I hit sink, it means okay. Let's copy the settings from the image we're viewing and apply them to the other images that are selected because I forgot to have auto sync turned on. I need to do it afterwards and then I can say exactly which setting should be applied should it be all of them. Or I could go down here and say, check non and now is only white downsized, messing with and so it depends if you want to do it interactively well, you're moving the sliders. That means you want auto sink on or if you forgot to do it because auto sink was turned off and you need to do it after the fact, you know, I've already adjusted this picture and I just need to somehow get it over to the other images that would be hitting the sink. But excuse me when you took move the sliders automatically changing that and all all the picture even have selected yes, it's automatically changing on lee that slider for all of the pictures you have selected, then you have to have thought of saint, but when you're finished, no okay, auto sink simply means adjust all selected where's it's turned off it means only a just one regardless of how many have selected, you don't have to, like. Turn off a non men between images is just a matter of you wanted to currently think about all selected or not, um and it's up to you. What is most useful?
