RickDB 10 Posted August 11, 2008 Capturing this in a single shot is difficult because there is very little space in the foreground. Even at 10mm (16mm 35mm equivalent) the facade is too wide and the converging verticals extreme. The answer is to take several overlapping shots and stitch them together. If you are not using a tripod, allow a large overlap between images to give accurate stitching. Cheers, RickDB Link to comment
spenaloza 0 Posted August 11, 2008 What can I say ! but just Great, it is an excellent work , Rick, thanks for sharing and the info , best regards //Salvador Link to comment
Pierre Dumas 411 Posted August 11, 2008 It wasn't shift lens mentioned in the technical data and I don't know how the convergence of the lines was avoided with a such a motif and such a wide lens! It seems to me the picture was taken from the ground point?! Maybe the good old PS has done the job! PDE Link to comment
milena_safrova 0 Posted August 11, 2008 I can only admire the way you managed to get the whole huge Cathedral into this photograph. The space in front of it is so small, no space to step back. Excellent picture, really, good lighting chosen, great details. Hats off Link to comment
RickDB 10 Posted August 12, 2008 ...I hope you can make use of this technique when you find yourselves with your backs to the wall and a great view in front! Pierre - I have not explained this too well. Perspective correction in PS is key to getting this right. With a single shot on my camera I would have about 7 mp of cathedral to manipulate - the corrections are too much and the image starts to fall apart pretty quickly when you start dragging the verticals into an upright position. The 5 overlapping shots I took were at 22 mm (35mm equivalent on 35mm) and each frame was the full 10 mp - after stitching together I probably had greater than a 30 mp image to manipulate - and this is the trick to obtaining a good quality image after application of large perspective corrections. The final psd file was a whopping 125mb which turned into a 12.5mb jpeg - so you do need some good computing power! Milena, you're familiar with Koln Cathedral and understand the problem well! I'm sure you could use even a point and shoot camera as long as it had a manual exposure function. As for the lighting, I'm afraid I was just lucky as I only had 3 h in Koln before getting the train back to Dusseldorf airport. Cheers, RickDB Link to comment
mdineen 0 Posted August 12, 2008 well worth the work you put into it. a magnificent cathedral, beautifully rendered. Link to comment
milena_safrova 0 Posted August 13, 2008 for you, Rick :-) I have been thinking about your technique. If you like to cope with really difficult tasks then visiting Prague is a must. What is in front of the Dom in Koln is a real golf course compared to the space in front of St. Vitus frontal. Literally a few meters ... :-) (see my night picture, that one without the horse, the front view). So ... :-) Cheers! Link to comment
