compressing a photograph’s proportions

(This refers to “squishing” the image area of a photograph vertically or horizontally to make the photo a different proportion without cropping.)

Compressing a photograph either horizontally or vertically — by even a tiny bit — disqualifies a photograph from P2, because everything in the photograph is reshaped by such actions.

As per P2, the only reason that anything in TTG photographs can ever be reshaped is to correct for lens/camera anomalies, the correction of which is #4 on TTG’s list of Allowable Changes.

All other reshaping (of anything, in any photograph, for any reason, no matter how small the change) disqualifies the result from P2 and TTG.

Note that cropping and overall downsizing do not disqualify photographs from TTG; see the list of TTG’s Allowable Changes.
