Camera App: 645pro with F4 b/w film and 645 format.
Location: Luxembourg Main Station, the new sidearm with the modern glass roof in front of the old station building. I took this photo late in the evening, as the station was deserted.
Additional apps used for post processing:
Frontview: to correct the lens distortion. The photos below show you how I did it.
Photo fx Ultra: for cropping and contrast.
PhotoForge2: for a slight re-sharpening.
Pixlromatic: for the frame.
A+Signature: for the copytight watermarks.
This is the original photo as taken with the 645pro. You can see clearly that even if you align one side to the camera grid (left) the lines on the other side are oblique. To correct this I used a neat little app called "Frontview".
This is the Frontview screen after loading my picture....
The first reference point is set....
Second reference point top left...
Third reference point down right....
Fourth reference point set top right. Note that the points follow the lines that shall be straight after processing.
Now tap the arrow to process the picture...
After this operation completed, I saved my picture and I opened it in Photo fx Ultra for cropping and enhancing. Then I opened the newly saved version in PhotoForge2 for a slight re-sharpening, added the frame in Pixlromatic and the copyright watermark in A+Signature.
I hate it when I photograph a building and some lines appear oblique, no matter what I do. The happier I was as I discovered "Frontview". You cannot only take photos with it and correct them, you can also load photos made with other apps to be corrected.
