Some months ago, I bought a cheap cradle for the phone, stuck it on the windscreen and fired off a series of shots as I drove up the freeway to band practice one rainy evening. I have a cable release (also cheap) which doesn't work on every camera app, but it does work on SlowShutter. I set the shutter speed to 'B' and just held the shutter open. In this case, for 14 seconds.
This is what I got. I thought I might get something a little more interesting if I could crank up the contrast and the colours. And improve the definition. Well, I would have to, as this is pretty dull.
So, I tried maxing out the ambience in Snapseed, which sent the image in the direction for me.
I cropped the image in Snapseed too, to the 16:9 ratio, to give the image a more wide-screen feel. Then I used TangledFX to enhance the contrast and definition. I think I started with the "Small Details" button, but I also played with settings in "Tune", reducing the scale effect factor right down, so it wasn't so obvious that the image had been 'tangled'.
Next, into touchRetouch to remove some imperfections caused by the windscreen. There were several, although the only one visible here is a dark mark in the bottom right hand corner.
By now, my image has a vaguely painterly nature, so I decided to enhance that by adding a texture from Photocopier. I chose "Velazquez".
Then to finish, I increased the saturation a little in Snapseed and added a vignette with the "Center Focus" button. It's no world champ, but I liked where I was able to take the image. It looks better big, just like rock 'n' roll sounds better up loud.
I shoot for fun, with a Sony A7II, a Mavic Pro and my trusty iPhone 6s.
