Shooting Big (aka Wide) Landscapes but not Wideangle

I am always had a loved of wide panoramic views. This have been even exaggerated as I travel around on my endless summer project. Australia looks better in wide view. However I am not a fan of the distorted view that extra wide angle lenses give. For example you can get the horizon horizontal and straight if you have it in the center of the photo when you take the exposure, but lifting the horizon up or down will result in a curves horizon in the final image. In a forest the tress on the edge of the photo will bend in. Building will get smaller towards the edges and very triangular above you. These are all features that can be used creatively, its just I don’t really like them and therefore don’t own a specific wide angle lens. (my Tamron 18-200mm zoom give me a decent width to play with)

Photo series used

I still like the wider view, so what do I do. I have always (even going back to film days) just taken a series of overlapping photos and cut and pasted them together. Now with digital tools I use software rather than scissors and glue. There are plenty of tools to do this but I like Microsoft’s ICE and Autostitch the best. They actually have a different look, closer to what you see with two eyes and head movement scanning across the scene rather than classic single point perspective. I’m certain that David Hockney noticed this well before me, in his joiners, grand canyon and bigger picture projects (all made with multiple images/panels) and specifically he does mention the limitation of cameras in his collaborative book Secret Knowledge: Rediscovering the Lost Techniques of the Old Masters with Charles Falco, There are now also lots of smartphone apps that will stitch panoramas on the go using the phones camera, they also show this wider perspective rather than the wide angle distortion of a wide angle lens and single image.

As Stitched by Autostitch (with ghosting)

However because the photos are taken in sequence (with inevitable time gaps between) they are prone to a few issues. First and most common issue is someone or something moves (like the man in the 5th. 6th. & 7th. frames), The stitching program will then produced “ghosting” (HDR set also suffer the same issue) in any areas of overlap across the areas of the movement in time. This can be a hassle to fix, and I often don’t or only fix the most obvious ghost. In this case I used OnOne Enhance’s magic (a context sensitive) eraser on the ghost in front of the moving man’s face and the whitish ghost of his hoodie. Some programs give you the option of masking out things not to be stitched (it can be a lot of work with limited success). Another common problem is the difficulty of hand holding and maintaining a level to the sequence as you turn. Wobbles can also lead to ghosting and sometimes bending of the horizon or failing to be able to stitch. This sequence was hand held and I was on a slippery wet rock and it was windy so despite my best efforts the last few frames are a little out of register, and you can see the resulting ghost in the timber slats on the side of the bridge. I decided not to attempt to modify them.

Photographer crush on Fisherman's Bridge at Canal Rocks The important outcome is the modified wider view does the magnificent curved walkway justice  (It is just a bridge to allow rock fisherman to safely fish in the canal but it is a wonderful construction)

How Wide can I go?

Whilst on my endless summer trips I’ve gone a bit overboard taking very wide panoramas. It very easy with a digital camera to rattle off the 30% overlapping images to make a stitched panorama and I have used Autostitch to do this mostly although Microsoft’s ICE is another great stitching program and there are lots of other programs and apps. Because the wide view suits so many of the vistas I’m visiting I’m also opening out my sketchbooks to paint across two adjacent Landscape pages. This is all wonderful and enjoyable in the field but it has a downside, it takes time, in fact the bigger the panorama I want the longer the stitching and other post processing of the photos takes. On busy travel and field days I simply run out of time and/or I’m likely to fall asleep waiting for the stitching to complete in the evening.

Sketch at Gypsy Point

As my LG phone got terminally ill, and misbehaved several times, I lashed out an got a new HTC U Play (why HTC, well it was not the cheapest but because my first HTC was super reliable and easy to use and is still going strong, as GPS in my camera bag, it was able to take over from the ailing LG). The UPlay was equally easy to use, the one downside is the beautiful case and screen as a bit slippery so a slip-on cover (red so I don’t leave it behind) was the first accessory. Then it was out to try out the camera, I just love it! Here is my first attempt at panorama mode.

Jell Park Lake Panorama

Now that did take a few seconds to stitch in the phone but it is a wonder panorama, I might have been able replicating this with a DSLR and autostitch, which would easily take over 5 minutes or longer!

Screen Captute of a recent 3 Across Instagram Post

My passion for the wide view has very much moved into my instagram accounts especially @apimageo, which is still very much stuck in the 3 across grid view (you have to look at my profile to see it). I also recently notice that @packtography (he’s worth a follow) includes the camera, exposure and post processing summary with most posts. I reckon this is a great idea, so I will try to keep up including such info. Sharing your settings to me is important as an insight to let other understand your work, BTW my flickr posts have always included the extra EXIF data automatically if you are interested.
