When photographic architecture, landscapes and even people, photographers often desire to increase detail and resolution, capture a wider angle or create a unique look that is impossible to achieve with standard camera gear. That’s where panorama photography comes in – it can be a great technique to utilize in order to accomplish such goals. Although the concept and the technique itself are fairly straightforward, panoramic photography often confuses many photographers. We often get many inquiries about this topic from our readers and one of the most frequently asked questions is about the specific type of gear to buy in order to produce stunning panoramas. And that’s certainly one of the biggest myths about panoramic photography – you rarely ever need such gear! Most of the panoramas I have stitched so far have been done without panoramic gear and although I do own a panoramic slider, I rarely ever get to use it. Read on this article on panorama photography tips to find out why!
At PL, we have written quite a bit about the subject of panoramic photography. A while ago I wrote a detailed tutorial on panorama photography, where I cover a lot of the basics of this technique. The topic was further expanded by a number of other contributors like John Sherman, who wrote an article on how to create HDR panoramas in Lightroom, Spencer Cox, who wrote an article on the hidden benefits of panorama photography, and my friend Brad Judy, who wrote an article on how to stitch images with Microsoft ICE. On top of all this, we have even written about a method of stitching panoramas when photographing people for that unique, shallow depth of field look, which was later expanded to a Lightroom tutorial, including an article on fixing panorama merging errors. In short, a lot has already been said about this technique, which is why I want to cover some specific panorama photography tips and the myths surrounding it.
1) Are Panoramic Heads Absolutely Required?
Let’s start with the biggest myth surrounding panoramic photography – that you always need a panoramic head. Many photographers advise that a panoramic head is absolutely required for proper stitching of panoramas and that it is a must-have piece of gear. That’s certainly NOT true and I would personally stay away from such unsupported statements. The fact of the matter is, panoramic photography gear is ONLY needed when the scene contains close foreground objects and if you are shooting with lenses other than tilt and shift. When you photograph from a high vantage point / overlook or a point where the nearest foreground object is located at infinity focus, you do not have any concerns with parallax. So you could easily make a large panorama without any special equipment. I have stitched many panoramas without any special equipment, including the Zabriskie Point panorama you see in the beginning of this article. Why don’t I use a panoramic head whenever I can? There are several reasons for this – let’s take a look at them in more detail.
1.1) Lack of Time for Proper Preparation / Testing
Lack of time is one of the biggest reasons why I rarely get to use a panoramic head. Although I do everything I can to prepare well in advance of shooting a particular scene (which I would have typically previously scouted and researched for), I don’t always have the time to set everything up for a panorama. Unfortunately, once you get into complex panoramas, especially the ones that involve multiple rows, it can take quite a bit of time to get everything fully leveled, prepared and tested. If there are any foreground objects, or if you shoot at longer focal lengths and parallax can be a potential issue, you would have to also make sure to get the camera and lens moved to their “no parallax” point (which you would need to know well ahead of time). And God forbid if you decided to zoom in / out (change your focal length) and forget about moving the setup accordingly – that’s a recipe for a potential disaster. In short, stitching complex panoramas takes time and patience, and if you should be prepared to deal with all those issues.
Another reason why I often don’t shoot panoramas is due to wind. If it is extremely windy, forget about panoramas. Not only does wind cause objects like trees and bushes to move, which would make it a real pain to try to stitch, but the wind would also shake your setup and potentially cause blur in your images. One of the biggest frustrations with shooting panoramas, is later discovering that a single image out of your sequence was blurry! I have had so many great panoramas, which I never ended up using, just because one or two images from the sequence was completely unusable. Why didn’t I pay enough attention in the field? That’s what the next section is all about – timing.
1.3) Condition Changes and Clouds – Exposure Time, Timing and Speed
When photographing critical moments like sunrise and sunset, where everything happens too quickly, you might regret the decision to shoot panoramas fairly quickly. Why? Because everything happens too quickly and you cannot quite do that with a panoramic setup, especially if it involves more than 5-6 exposures. When shooting at low light levels, which is typically the case when you shoot sunrise / sunset moments, if your exposure time is too long (say more than half a second), shooting panoramas can be a bad choice. First of all, light levels will change too quickly during these peak moments. Even if you shoot in full manual or lock your exposure (which is required for proper panorama stitching), by the time you are done with the whole panorama, the brightness of the scene might have drastically changed, making it impossible to produce an even panorama. On top of that, long exposures would cause the scene to change too! For example, if you have clouds in your scene, even half a second might be too long for such panoramas, since the clouds would be in a completely different place in your last shot of the sequence. Lastly, if you do decide to shoot changing conditions, you will need to learn how to do everything at a very fast pace. So you need to be fully aware of such potential – if conditions change too quickly, shooting a panorama might be a complete waste of your time.
1.4) Distractions and Scenes Not Worth Stitching
Many photographers, including myself, end up shooting panoramas of scenes that are not worth shooting in the first place. Sometimes the scene itself is not very photogenic, sometimes there are too many distracting elements and other times, the light is just too flat. I have taken countless panoramas that I never stitched, because I would not have been pleased with the results. It is one thing if you are starting out and shooting panoramas for practice, but totally different if you find yourself shooting those pointless panoramas that are no different than your average “crap shot”. Sometimes you are far better off spending your extra time scouting locations and finding something interesting to photograph, than wasting your time figuring out those “no parallax” points or sitting and waiting for hours trying to get your computer to finish the stitching process. And how about spending a lot of money on expensive panoramic heads that are too heavy to lug around with in the field? I value my time and if I see a scene that is absolutely not worth shooting, I won’t do it. The more crap you shoot, the more time you waste. More images to import, more images to store and more time to waste just to figure out at the end that it was all not worth the effort you put into it.
1.5) Storage and Computer Requirements
Another reason why you might want to stay away from panoramas is huge storage and fast computer needs. Guess how big that 400 MP of Zabriskie Point panorama is? Almost 4 GB! Yes, that’s a single file with all the details in it. In fact, Lightroom could not even handle such a file, because I had to save it in a different format (PSB), as files over 2 GB cannot be saved in the common TIFF format. But that’s not the worst part – the process of stitching the panorama was quite painful. Since I now prefer Lightroom to stitch panoramas (due to the fact that Lightroom 6 / CC is capable of creating DNG files that can be edited just like RAW images), multi-row panoramas can take a really long time to stitch and in some cases, they cause Lightroom to crash completely. For the Zabriskie Point panorama, I had to retry about 10 times before the panorama finally stitched without issues. In between, I tried out PTGui as well and although it did a great job overall, it was still not able to produce a DNG file. So once Lightroom finally did it, I ended up going to the DNG version, as I had more editing room to play with. My second part of the struggle was the editing process. Both Photoshop and Lightroom made my fast PC look like junk, literally. I quickly realized that 32 GB of RAM was inadequate and if I wanted to speed everything up, I would have to down-sample my panorama to smaller resolution. Keep all of this in mind. Unless you only shoot a few images, those multi-row panoramas might give you a lot of different kinds of headache, which start after you offload those images to your computer. I cannot even imagine what folks like Aaron Priest go through when they stitch multi-row panoramas shot in HDR! (by the way, check out his excellent article on photographing the Milky Way).
2) Why Shoot Panoramas
With all this talk about why I often choose not to shoot panoramas, you might have gotten a feeling that I am against panoramic photography. No, that’s definitely not the case. I do shoot panoramas when the conditions call for them and I rarely regret my decision after the fact. Panoramic photography is a wonderful technique for many reasons – Spencer did a great job at explaining those in his Hidden Benefits of Panorama Photography article. Being able to get a different angle, increase resolution for ultra-large and super detailed prints are the primary reasons why I sometimes shoot panoramas. Over time, I learned how to scout locations for panoramic photography, anticipate light conditions and set up my gear quickly for proper single row or multi-row panoramas. As you practice this technique in the field, you too will find out what works and what does not for you. Despite all the factors and disadvantages pointed out above, I would still encourage everyone to give panoramic photography a try!
Just take a look at the below crop detail from the Zabriskie Point panorama:
At 400 MP, it has so much detail that I could make it into a huge wall-size print, or a smaller super-high resolution print that you could pixel-peep at close distances.
3) Parallax and the Need for Panoramic Equipment
Now that we talked about cases where you do not need a panoramic head, let’s talk about situations that call for using such a device. As I have already pointed out earlier, you only need to use a panoramic head when there are potential issues with parallax, which means that you are dealing with foreground objects. Why do you need to worry about parallax? Well, just like when you see what happens when you extend your finger and look at the scene with one eye, then notice changes in the background when you look at the same scene with your other eye, the same thing happens when your lens rotates around the camera base. Take a look at the below illustration that explains this phenomenon, courtesy of Wikipedia:
When your lens moves around the tripod base of your camera, the background relative to your foreground subject would appear differently between shots taken at different framing positions. Although many software packages today have methods to deal with slight parallax issues, severe parallax errors yield to badly stitched panoramas. In extreme cases, software sometimes cannot even stitch such panoramas.
The solution is to use proper panoramic equipment, which would allow moving the rotating base away from the camera to the entrance pupil of the lens. Once properly set up and the camera rotates around the entrance pupil of the lens, or the “no parallax” point as often referred, software won’t have any problems stitching such panoramas and there won’t be any issues in the resulting images.
