Astrophotography – what’s my shape.
One of the challenges that I have shooting with ultra wide angle lenses for the milky way panoramas. If you take a single frame, you know that panoramas can look a little stretched at times as the stitch can warp the image in order to make it match. I like trying to get a natural looking milky way core where possible and also like a nice rounded arch – but sometimes it’s a little bit of a trade off between the two. There is also the other form of milky way – that I “straighten” out the milky way panorama at the expense of a very substantial distortion to the sides of the panorama as it warps it in. Simply put – if you’re doing a milky way panorama, expect some form of distortion or warping in the process.
All these images look a bit over exposed since I shoot at 25-30s ISO 6400 F2.8 for these ones. I expose them more than what is required as part of my image quality to reduce noise.
I didn’t really like this one – although the arch is a has a nice rounded feel, the core stretches out a bit and makes it feel like someones grabbing the sides of my head and pulling – try again :P.
This style is more artistic – certainly not for this particular image though. I use this method where the milky way core is higher in the sky. I was a bit tired here – and should have waited a bit longer to do one of these stitches – the rocks look a bit like a mountain.
This appears to be a “normal” sort of panorama and you can see the images sequenced in an orderly regular fashion. To be honest, while I used this method for the image, I wasn’t very happy with it since it does make the milky way appear a bit too rectangular. But the core is more natural in this instance and not as stretched as the first one.
On a setting milky way – this is the regular sort of stitch. I don’t really like how the milky way core here is a bit stretched and making it feel a bit bloated on the left. A bit like when I’ve had too much dairy.
Ur – maybe not 😉 Just wondered what it would be like to straighten it out.
This particular stitch stretched it vertically – so if the first one was bloated, this one is about to burst. I think I’ve had too much dairy.
I preferred this sort in this instance. Didn’t stretch out the milky way as much and felt a bit more natural.
I do note however that in each of the above examples, there are ways around shifting a little bit here and there and maintaining the integrity of the image to reduce some of the exaggerations. I just wanted to demonstrate that there are many different looks and I like having a nice arch and minimising the stretching of the milky way core.
