I've been looking at ways to improve my digital photography workflow, so I checked out a bunch of software over the past few weeks. I have a few suggestions on this front and after v0.7 release in 2-3 weeks i will start to implement those. If you can provide ColorChecker raw images of those camera enhanced color matrices could be implemented, you really should have this talk with Pascal (our color manager).ĭarktable IS mainly a rawconverter and have alot of drawbacks when we talking about using it as a manager still it does handle your images,colorlabes/taggin ala XMP, BUT the current implementation of tagging,filtering and collections are pretty simple and needs a big rework. Why use colorprofiles with jpegs ? where the raw data already has been modified ?

However, for organising and adjusting images and more importantly database management and filter presets, I would really be interested in something that can offer a real viable alternative to Light Room.ĭoes Darktable support colour profiles for pro cameras like Mamiya, Leaf, Hasselblad etc? It's still the best for both of those things, so no point changing.
I'm not interested in using it as a raw converter as I rarely shoot raw nowadays and if I do I convert using Capture One. I wish you succes.I'm interested in trying out this app having read through the thread. Do you have this image in bigger resolution?Īnother thing here is that one vanishing point is very clear, but the other vanishing point is more difficult to find, because you can only retrieve that information from the right side of the tower. I would like to help you to find this position, but then a image with a bigger resolution would be helpful. Is the big tower square? Maybe then it is possible to find the camera position. On this line your "third vanishing point" must be chosen, so here is some freedom as long as you will keep a proper perspective triangle. Then we can draw a line perpendicular to the "horizon" and through the principal point. So we must first find this "principal point". Then we can find the third vanishing point. But also we need to find the principal point of the image to have the ratios look correct within this "three point perspective". (edit2: the problem is to find a nice third vanishing point for the lines that are now vertical and parallel. But then you must know a ratio of something rectangular on a perspective plane. With some "difficult" use of "descriptive geometry"(link is German Wikipedia, because there is better explanation), it is sometimes possible to get some more information. When something is in "two point perspective", it has not the information of a "three point perspective". With the tilt shift, the image is now "two point perspective". The lines of the building are horribly straight. I have a picture that is probably taken with a tilt shift lens. It is called "camera mapping", Blender Guru explains it here:
If you want another camera position, you have to model this in 3d (Blender of course). You can not change the camera position, because then you had to go back in time and ask the photographer to change the position. Maybe it is possible with software as "HUGIN" as "denzjos" already wrote to you.īut then still it must be a change with the same original camera position. If you want to proper change the perspective of something like this, you must know a lot of perspective.

The problem is: how to manipulate the corners of the image to get a proper "three point perspective" image again, to get the inverse of the tilt shift.) Then it is easy to draw the vanishing lines precise.

A nice free and open source program to work with this is: "LibreCAD". ( edit: but I think also that the vanishing lines will scale with manupilating the corners of the image, as you said on the Dutch forum. I see you also posted this question on a Dutch GIMP forum (I'm not a user/poster there):īetter explanation then user "denzjos" gives there, I can't give.
