For users of Photoshop software, share the post-synthesis animation tutorials for long exposure photography.
First, watch two films first. The first one was a photo of a star track that I first used to directly use the B gate + shutter line for a long exposure.
The specific parameters above are: Nikon D600,17mm,iso 100,f8,3429.7s, nearly 58min exposure time, recorded in this nearly one hours in the sky track. But it is not difficult to see that a long time exposure is the image of more noise. A lot of people who know about long exposures should know how much exposure can hurt a digital camera for such a long time. And the noise in the picture is precisely because the exposure time is too long, there is hot noise, affecting the quality.
The other is a photo of the star-rail plus lightning that I've taken several times in the early stages of the synthesis.
The specific parameters of this diagram are: Early shooting using interval shooting, Nikon D600,35mm,f3.5,iso 500,30s, interval shooting time 30s, a total of 160 shots, the total length of the shooting 80min. As you can see, the noise in the film is well controlled, the details are recorded intact, and the orbit of the sky is the same as that recorded for a long time exposure.
Next look at a picture, is still a late synthesis, but a similar to the satellite movement in the picture left traces are intermittent, not connected, which is the interval between the time and exposure time of the gap caused by the middle of the breakpoint. Through my explanation, I think we should all know what I mean by the late synthesis of long exposure, and about the text mentioned in the interval shooting (delay shooting), still do not know the friends can be moving to "talk about time-lapse photography and the production of dynamic pictures," below me for a specific post synthesis.
About the late synthesis of the software we can use more, here I recommend a relatively simple software startrails, it is more convenient to use. After downloading and installing the software, our two-machine operation will pop up the following dialog box, let us choose the operation language, choose English click OK.
Then in the Open software interface, we can see the operation of the software on the upper left corner a few buttons, the first is to add a picture, the desired combination of photos added to the left of the files, the second is to select the foreground image, that is, at the end of the synthesis using a picture to restore the details of the exposure of the photo; the third one knows, To save the fourth one, I was useless to, do not know what role, O (∩_∩) o~, the fourth is the synthesis button, click Start Synthesis; The fifth is a synthetic video.
After understanding the software, it is time to deal with the photos, click on the Open Picture button, select all the photos to be synthesized, if you need to make up the foreground details, continue to click on the second button to add photos, then click on the Fifth button, which is the same as the Software icon button, into the composite
As shown above, there are two options, select the second, directly click OK, the software will begin to automatically synthesize the picture. If you select the first item, the following additional options are lightened, such as selecting the option in the following figure red box, which opens in the process of synthesizing a photo each of which stores a photo, path is the location where the photo is stored, and filename is the naming convention and picture format for the filename.
In the software automatic synthesis picture process, the software displays the synthesis progress at the bottom, if needs to terminate halfway, presses the ESC key, when the synthesis completes, clicks on the upper left corner saves the button, may the final picture save, also completes the entire synthesis process.
As mentioned above, we simply completed a long time exposure photo of the post synthesis, this is the beginning of the article to see the star rail and lightning coexistence of photos, will not be dark when the sky and the dark days of lightning placed in a picture, this is a long time exposure can bring to everyone's different scenery photos, And we also through another way that is delayed photography also got a long time exposure photos, really can kill two birds, why not?
At the end of the article, I would like to tell you that a good later period can not make up for the early photo of too many deficiencies, so before this tutorial, we should first have a stable tripod and can hold the normal exposure of the delay photography techniques. Only this perfect prophase, can better let later get unexpected effect. Here I would add a few things to note:
① take photos for later consideration, exposure time and the length of the gap between the length of not more than 5s, or later synthesis of the film will be intermittent, if shooting meteors and other mobile trajectory, this means may not be shot continuously, theoretically exposure time and spacing when the appearance can, but I have tried.
② this kind of late synthetic means can also be used to shoot the foreground with strong light, because the normal long exposure will make the foreground exposed, so compared to a single exposure time is shorter, in the late synthesis we can save more details.
③ There is a point, but also here to tell you, is in the synthesis process, I mentioned that there is a way of storage in the synthesis process each overlay a picture on the additional storage of a photo, the careful shadow friend may ask such a step what is the use? Here, I upload a dynamic picture, let the shadow friend consider it yourself. O (∩_∩) o~
Okay, the above information is small to give you photoshop this software users of the long exposure photography of the post-synthesis animation tutorial share the full content, you see here the users of Photoshop software, small knitting believe you are now very clear the method of it, Hope that the small series to share the help of everyone.
