BA=A(Pi/180)(R+KxT)

Thats truly awesome David, the curve of the buildings seems to be mirrored by the swirling cloud. Very dramatic. The title did leave me scratching my head slightly though, never was any good at equations.

Best Wishes, Dave.

Perfect light, sky and details - deserves the highest rate!

Excellent composition in B/N between sky and buildings. Congrats

Congrats David.

Nice picture David.

Your formula (to calculate steel plate bending ? ? ?) could be ( r + k + t).

But maybe impossible in this case (?)

Whatever. Well done.

Greetings from Valencia...

Cheers for any comments on this site, I really appreciate it. Cheers Dave, I may start start posting more and more.

Well spotted Rolph, its a formula for calculating bending, very applicable in this case and totally pointless like you say.

More to come from Dusseldorf, Shanghai and lastly a revisit to Valencia before I start a commission shooting the UK in summer time.

I like your image,maybe for several reasons.One the angle of the capture.Two this touch of clouds resting monotony to the sky.Three, the b&w tone applied.Four, the sinuous lines in the building (Frank Gerhry).Five the exposure. Surely will be  a lot  reasons more,  but I thought that these ones be the most important for me.Best regards

Beautiful composition so well rendered in B&W, i love the perspective and the sky.

Haha, I get it.  the title is the formula for determining Bend Allowance, which is a factor used in determining the length of a flat piece of sheet metal required to form to specific dimensions after it is bent.

The formula results in the length of the cord at the neutral line of the bend.  It varies depending on sheet thickness (T) the inside radius of the bend ®  and the angle the sheet is bent at (A).  Locating the neutral line requires K-factor (K), which requires another formula (and usually some testing) to determine.
