How could you perhaps read on Facebook, I will Next year, two large tour workshops near the desert Liwa Dubai carry out, as well as in the Lavender fields of Valensole in France. Also, I play one with the thoughts in Bilbao, Spain to provide project off the ground ... You will soon enough Experienced. In any case, we come to a small Photoshop Lesson...
When I was the first time in Bilbao, I can visit a plethora of beautiful places, with gorgeous lighting situations and countless photos. It is at this place that I first occupied myself intensively with a photographic technique, which now almost always accompanied me. While there
it situations and images, when it is not usually necessary, such as zoom shots or pure Milky photos with little foreground. To make it short... It's about the "Fokus Stacking".
Originally a technique which is essential especially for macro photography. Anyone who has been busy ever, will know very well how difficult it is a continuous field with a macro lens or. to achieve motive. The autofocus can forget the same times ahead. In the recordings one is first struck by the shallow depth of field. Also, the close of the aperture of f / 22 brings little, But on the contrary. This makes the image as a whole
again blurred because of the diffraction blur. Macro photography is a science in itself and we now want to not deal with it, although the principle is the same as in landscape photography is, though less violently.
In landscape photography we do have above all the desire or the ambition to, a complete focus on the whole picture to get. So from the foreground over the middle up to the background. It is often the so-called "hyperfocal distance" worked. It is the maximum range, to map a photo from the front to back sharply. In addition there are tables on this focal point and is completely dependent on, which focal length, Aperture and sensor size is used for. You can calculate this distance online such as here:
Or via appropriate apps like "DoF Calc" or "HyperFocal".
To sometimes show off an example we have the following settings available. A Canon 5D3 (full frame), a focal length of 16mm and an aperture of 11. The result of the hyper focal distance is now about. 80 cm. The depth of field extends more or less is about half the hyperfocal distance to infinity from. If we now focus on the point, of about 80 cm away from the camera, so do by 40 cm to infinity, a complete sharpness have ensured ... should.
It becomes more difficult when you have a large spectrum of the foreground, the camera is just above the ground, a wide-angle lens used, and to all "evil" then even a portrait photo created. Since the above-explained hyperfocal distance does not help much. But with the focus stacking one can apply a technique that really created through and through a sharp image. Long story short... Let's start times 😀
For this I'll you a PSD provide with a photo from the region Sonabia in Spain. Again, a focus stacking has been created consisting of the foreground, Middle ground and background.
Before we start with the actual technology itself, I'd give you a little tip with on the way. Take first time in front of a small development in Lightroom or Camera Raw. Here, you can of course quite work freely after your style, but especially I want to put you to the heart to choose the chromatic aberration, thus disappear the annoying ro-purple edges on the image. Now we can start.
As mentioned, I have 3 Sharpness levels created, also 3 Photos. These are in Photoshop open as planes like the picture shown and all 3 Level having to be marked. You can also rename the plains how I did it.
After that you go on the top left menu item "To edit" and selects the mode "Auto-Align Layers"
A new window will appear, where you can set the various parameters Stacking. According to my experience, Photoshop does a very good job with the point "Auto". In the
Vignette You can take out the tick, however, I recommend the additional precision alignment, the "to select geometric distortion. then click OK to the stacking start procedure.
Now we have a very well-aligned image and if you zoom to recognize even the improved sharpness over the whole image. But it is not quite perfect. For this, because missing a crucial step we approach next. We will order the, Stacking by the resulting edge, first time not worry further drum. We do later.
to the levels remain highlighted and next we go into the actual focus stacking menu to all the magic unfold. We go again to the menu item "To edit". But this time the mode "Auto-Blend Layers".
Again appears a small adjustment window, that invites us to the mode "Panorama" or "The bar" to select. Of course, we choose "The bar" and in addition, we put a tick in spot "Seamless tones and colors". The point "Content-based filling for transparent areas is not necessary. By this point, Photoshop fills only the transparent edge automatically based on its content together with the environment. First, almost never worked satisfactorily and secondly because we are cut off edge later anyway.
Now we see the almost finished result. All three focus planes are now provided with an additional mask that show exactly where the sharpness (shown in white) lag.
Together, we now have a knotless image.
2 Points need to be considered after. It can at times also happen that somewhere a few pixels were displayed incorrectly The only solution manually nachzuhelfen about a correction temple or even a slight masking of the area concerned. So zooms purely into the picture and take the time for a review. Another aspect are the clouds. Is
Namely well be, that during the recording or. while adjusting the focus therebetween, the clouds so move quickly, that make the finished picture stacked some errors noticeable. If you look at this example just to heaven, will know you that in a few places repeat the cloud pattern. This can in these circumstances not be avoided but in any case very quickly and easily be corrected. Just take one to each photo (most of the background) and putting it on the stacked image with a black mask a white brush and low opacity, mask out the job, you are to your satisfaction.
And this is what the finished picture from:
This technique is very demanding or rather time consuming, particularly requires if the light situation rapidly changing act rapid, before it's all over. But it is absolutely promising in any case and I use it myself very often like.
I hope I could you be a little more helpful and Feel free open questions here in the comments feature set, so that I can help you, of course in case of doubt.
