“I m tony northrup. And for my book nstunning digital photography. I d like to to show you nhow to take photos of star trails now if you nhappen to in the northern hemisphere. You ll be able to spot the north star nwhich resides right up here about the planet.
Well quite a ways in the distance. And it seems to remain stationary the ntrip to the north star is that every other star guy in the northern nhemisphere were involved around and then why should ncreate these circular star trails anytime. You re pointed north nstar trails. Start and and right here at your ncomputer per.
Step is to identify a good night to go out and take a picture out star ntrails. The things you look for our really cold and dry night. Now you want to be cold. Because the air ntends to be a little bit drier and clear and they will cause class ndiffraction.
The incoming light basically wields the nsea. The stars much sharper. You also want a night with no moon. What nso ever any sort of moon if it s going to nbe in that part this guy is going to cast light in the sky.
It s going to nfactory thing. You just won t be able to see the stars as sharply. So what i do is i open up my there right nafter this kind of thing. That photographers a members its free for a windows and mac ni put in their location.
Then i m going to be at and it tells me the moon rise and set ntime. So you can see that the moon is rising at n643 and its setting at our 455 p. Am. So i should be able to take pictures nin.
The middle of the night and not have them unlike interfere with nit now. We also need to find a location. The location should be as far from any nsort of street lights or city lights as possible even if the streetlight isn t in the nframe. What you find is that the life ministry.
They still gets to practice in nthe air and mixing little bit less clear. Doesn t mean you can t go in your nbackyard and neighborhood and take some star trails. But it s going to turn out nbetter. But farther away you get from your nstreet lights.
Now the next up is going to be to set up nyour camera. And i m still going to do this inside for one it s gonna be much easier for nyou to see if it s not in the middle of the night and to you re gonna need to do this by nhand in the day like to make sure you know nhow when you get out there under the right conditions for star trails. It s ngoing to be hitch pitch. Black.
You might be in the nseat then you re going to see the buttons on your camera. You won t know what you doing you nprobably also be cold in your fingers will start to go. Numb star trails can be really physically ndemanding. So it s really important you know exactly how to set up your camera nand do it.
In the daylight first and then when you get out there is going to be nmuch easier for you just because it is going nto. Be talking or bring a flashlight or better get a head lamp. Nthat you can easily turn on up. So.
Here s what you need for your ncamera. Need yourself a good steady tripod. The nbigger and heavier the better it doesn t hurt if you have neither above a level that you can put on top of your camera or electronic level in your camera. And nthe reason for that is that at night.
It s really hard to get your ncamera level. Because it s going to be some dark you re looking to the viewfinder and nchina sea the horizon. And you re just not going to be able to ntell now they have your camera on a released a ntripod and you have a level you re going to set up your camera nfirst thing. I like to do is attach a really wide angle lens the more wide nangle.
The better because it s good to capture as much in the sky as you npossibly can set that lands to manual focus and then adjusts the focus to be near infinity. Now as you look at the nfocus ring on it you re going to see a little ninfinity symbol and a line. You want to focus at the wine that mark nsince. Then the and not just all the way to one end up your camera nbecause.
Most lenders focus past infinity. So focus your lands to the ninfinity marking. Now. But you camera into manual nmode.
You want is what the shutter speed have n38 seconds. And an aperture up act for or whatever nthe lowest ebb that number your lawn. Supports is now such a. I so too 1600 and take a test shot now when you take nthis shot is going to take 30 seconds so start it and then just wait around don t also your camera don t mess with nthe one can be completely still at that thirty seconds elapse is you want to zoom into your picture npreview and then zoom.
All the way in so you can see individual npixels make sure that the stars are nice and nsharp if they re not sharp. Then you need to go back and adjust the focus a little nbit and retested until they are sharp. Now that you have your camera setup and nthe pixels are nice and sharp. We re going to take a dark frame shot so nwhat you can do is put a lens cap on your lens or keep all my advice and get nyour lens caps.
I just put a hat or coat. Or something nover your lens cap so it s completely dark nand. Then again take that same thirty second shot. It s going to be nmostly black frame.
But what happens is cameras going to record some noise. This nis just mb in no way is it will be bright pixels that don t work properly nindustry stuff going on with the sensor every camera has nothing to be worried nabout. But when we won the pictures too soft for nlater williams attract out that dark frame nwhat. All do is to create norway s free images on the rest out the npictures in the series.
We set up our camera for 30 second exposure earlier now so the nshutter for continuous shooting. It s the same mode you d use nfor sports where you hold the shutter down and just nclick click click click click click click just keeps taking pictures so i do that nwith a 30 second exposure but it works great so now they have your shutters that too ncontinuous. You re going to hook up a remote shutter release just anything that will lock the shutter open nso. I have one such device here this is a fifteen dollar remote shutter timer and a i came to a brand is because nit generic and their lease under a bunch of different names.
That s in it under their young own brand and such npetty and a handful. Peter um. Anyway. It ll look like this it ll cost nyou.
Like 15 20. Bucks american and you don t even need. The timer nfeatures for right now. All you need is the slider that allows you to cold the shutter open this is exactly like holding the shutter nbutton down on your camera and just keeping your nfinger there for hours.
But if you did that you be shaken a camera naround and you probably get pretty bored sup you plug this into the camera makes you nget one that matches your camera model because they re different connectors and then lot the shower open and your on nyour way. You can was going to be taking new shot nevery 30 seconds. So go do some light painting or read a nbook with flashlight and keep yourself busy nwhile your camera works is going to take hours does is that your camera. Though nbecause as the temperature changes condensation ncan form an alliance up depends how humid as and how much ndoctors changing.
But i like to check my camera every 10 nor 15 minutes or so special concern the summer and maybe a little more humid you have to get up there and just wipe nthe lands claimed so bring yourself in absorbent went free cough and just like that lansdowne every nnow and then otherwise you ll get all this ncondensation on the lands at war absolutely run the pictures get going it may be 10 15 minutes. Usable npictures. Where can we shouldn t keep an eye on nthe sky to if a cloud rolls past will happen is it nwill ruin. All your star trail.
That has happened ntime and time again i got text our jail pictures as nice and clear when i started than 20 nminutes and clouds roll past and they might come and go in just a ncouple minutes. But they ll be locked into your long nexposure annual to see the streak. A white along nbe attractive or anything and a pretty much bail on it if any sort nof clouds roll. And that s why i want to pick a nice clear nnight.
We re not predicting any sort of clouds. What so ever up how to stay out too as long as you can i took my exposure at about two and a half nhours that was over 300 different thirty second nexposures and stack them. So you will see what those look like. But the long you stay out the better now nthat you have your exposures.
It s time to go back to the ncomputer and copied those pictures to your ncomputer now i like to use lightroom and process nthe raw files. My room allows me to easily napply the same setup settings to the entire ngroup photo. So which is even get these pictures on nthere is the same thing that you ll see on any night photography. Picture your npolicy is it ll be really orange.
And the colors will look at it also you nneed to play with the white balance. Some and probably need to adjust the exposure nyou. Want the stars to be nice and bright in the sky to be nice and dark so just nthe black levels and the white levels. But apply the exact same settings to all those pictures.
Now we re going to export those pictures as jay pag files into a single folder with those pictures. Exported. We can now nopen up the application. They like to use and it s called star stacks so let s do that now you gonna quit that first toolbar button nto open up the images been an easy with a slight all nthe pictures in a folder is to press control day.
Now you can see all your input images in nhere that s what that s second to our button to subtract that your dark frame it happen captured are crammed nthat s okay it just helps reduce your noise. A little bit now before you process. The images you nneed to go over into the preferences tab you can open it by nclicking. The gear icon here and the blending mode.
I m ngoing to ask you to pick gap filling this works. The best is not nselected by default. Though. And if you had dark images be sure to nselect the subtract dark images checkbox as we all you need to do so up next you hit that last button.
Which is start processing and their ncomputers going to run for a while once it s done you re ready to finish up and save your final photo. The gap filling no doubt stars tax will fill in nsome gaps and gaps are pretty common and they have been for a couple reasons. None maybe you had to stop a camper secondly clean the condensation of the lands or if you ran noutta batteries and yes walked in a nice warm battery to keep the camera going nsometimes a somebody walks in front of your camera. Nand runs a particular exposure or maybe a light shine then anyone into nany had totally different.
If you re really not picky about it might take out the frames that have airplanes flying nthrough them. Because you don t like that dotted line can running your star trails and nany of those missing frames gonna cause a slight gap in your star trails. So the gap billing nmode here can actually those in for you. It s pretty smart.
It njust looks for the star trails and then fills in any gaps in them. So nwhat you gonna do is click this wrench icon over on the nright and it s like the show threshold overlay checkbox. They can adjust this threshold nhere until it shows gesture star trails. And green.
The causing your shot is to the nhorizon. The more interference gonna get and the nless useful the gap filling tool is going to nbe. But i still find it helpful so when a justice until pretty much just nthe stars are green. And you don t have anything else in green and then just nweek the amount to fill in the gaps as efficiently as possible basically with the amount you need nactually save the file file.
And if the salsa gaps in their ncrate. The amount of some save the file again and continue that ninto you happy with the process. So the gap filling to war tweet you can finally save your final taping nfile. It s a little tricky party.
The user interface here but the save as button is actually the third nbutton on the toolbar don t click this button accidentally it nlooks a lot like the disc button here click this button start processing and nthen you re gonna be waiting an hour again like computer. Processor. Pictures. Nup be sure to click that third save as nbutton and save that jay pag file.
I think any npicture you share with friends. You should take the time to at so here nis. My final edited star trails picture. I had nto go in and tweak the levels.
A little bit make nthe stars little clear. And they ve been brushed and a separate nforeground up the building just taken from one the single shots and the reason nfor that is is you re having a outing with somebody nstanding digital photography. Readers and they were doing light npainting so that light painting showed up into my pictures not a big deal because i was stacking npictures anyway so i just act the foreground from one image and kept the combine star ntrails to produce this final result now night photography is nchallenging especially in role areas. So make sure you work through the npractices in chapter.
