Once you import the images you need to press the button labeled 'Startrails' and you will be presented with some options, one of the options is for blendmode i reccomend using 'Lighten-Screen-Blend' because this produces a significantly better final product. Head to the top of the application and click 'Open images' this will then prompt you to select the folder where you saved your images.When you open the application it will show a blank interface but that is what it is supposed to look like. Download an application called Startrails which is available for Windows.Although this time-lapse is fun to watch on your camera it is not the startrail image you wanted to take so you must import your photos onto a computer and save them all in one folder. However if you cycle through the pictures on your camera quickly you will see a time-lapse of the stars moving across the sky. You will notice when you look at the images that they do not look like startrail images but instead look like static photos of the stars. After you have left your camera taking pictures for the desired length of time you can stop the intervalometer.Leave the camera to take pictures for the length of time you wish to capture startrails for (as before I recommend 30 minutes as the minimum).Plug the Intervalometer into your DSLR and set it to take a photo every 30 seconds this is the same as taking pictures constantly because each exposure is 30 seconds long.Set your shutter speed to the longest length possible (on my camera this is 30 seconds) and your ISO relatively low (I tend to use ISO 200).Set up your Camera, with its aperture open wide, pointed up at the stars.The open aperture will make the stars much brighter but because of the nature of this method it will not result in as much light pollution as the first method.This method is not as simple as the first however I believe it produces significantly better images which do not have the same problems of noise and light pollution.įor this method you will need an intervalometer ( I use the Neewer RM-VPR1 which costs £15, however some camereas have built in intervalometers). The aperture is yours to experiment with as different apertures will produce different effects on the image. After the camera has been exposed for as long as you would like (I would recommend 30 minutes as the minimum time the camera has to be exposed in order to capture any noticeable trails.) release the shutter button and the camera will save the picture to your memory card.įor this method I would recommend using a relatively low ISO to try and minimise noise.Usea shutter remote with a lockable shutter button to take an exposure (Or if you do not have access to this you could simply use duct tape to hold down the shutter release button if you are going to do this be very careful, when applying the tape, to avoid moving the camera because even the slightest movement could ruin the whole exposure.).This means the sensor will continue to record light for as long as the shutter button is held down. Focus your camera to Infinity (the furthest distance possible that the lens can focus on).Set your camera up on a tripod pointing at the sky.To take Startrail Photographs with one continuous exposure is very simple: This method is the most simple of the two but has the downside of resulting in an image that can be effected by noise and visible light pollution.
