Corresponding symmetry

Thanks in advanced for your welcome critiques. My best regards.

Hola Markku. Here it is. Abrazos.

is really interesting, and I like it. Maybe the slight tilting to the left doesn't fit - but this is my opinion, ciao, thank you for sharing, Giuseppe

Hola Giuseppe. Your are right, it is just a little little bit tilted but you have detected it, nice eye. I don't like that also and I will correct it. Thanks a lot. Abrazos.

Hello, and thanks for remembering this case. Your timing here is excellent, just look how the sidelight is just illuminating those vertical seams. Well, I could have lived without those clouds up there, but on just can't get everything. OK.

 

Giuseppe is too fast for me, and he already pointed out the tilt. I too played a little Eagle Eyes game with this and noticed something that bothers me: presuming the wall is truly vertical, as the tree trunk too, then those fence posts up there are not, or what do you think, Jose Angel? You know the truth as our local witness, so to say.

Hola Markku. Thanks again for your nice time with this shot. Lately I don't have enough time to be update with my friends and shots. Now here it is about 01:15 and I should be sleeping :-) but first thing first. I have been trying to find the right vertical angle for this shot but after three tries I don't feel it still nice enough, it is dificult because the angled perspective. About those metalic post on top of the wall, yes, they aren't vertical but the wall is perfectly plumb. Abrazos. P.D. In Senegal there is a saying: "White people have watches but they don't have time"

Yes, correcting perspective distortion can be tricky, and only hard work and more excersise can help. This might help to get further:

 

As you are about to turn the verticals parallell but fail, try to rotate the image ever so slightly in order to turn the not yet parallel lines symmetrical, and the fine tune again the correction of the verticals. Unfortunately right now I don't have the values I used on my corrected version. Sometimes less than one degree is the key to success...
