In day 10 of my #31dayphotochallenge I took this picture of this long exposure picture with my #GooglePixel as usual and edited with Adobe Photoshop CC for mobile devices. Check it out here if you want a great editing software on the go: http://amzn.to/2AqG9UK. I wasn't sure if I could even do this on my phone but lo and behold ... there's an app for that!
I went through a couple of pictures to get to this one here. Granted it isn't as awesome as if I used my much more expensive camera to shoot this, cellphones do have their limitations and one of them is low light due to the small sensors. I had my cellphone on a suction cup mount attached to my windshield but there was a bit of shake to it and with long exposures you need 0 shake for it to come out flawless. But I'm sure you get the basic jist of what I was going for here. Long exposure pictures deal with leaving the sensor open for a longer that usual time to allow more light to come in and thus you get there light streak effect. Try it and share your results with me. I would love to see what you come up with!
