There are cool little accessory levels that snap into the flash shoe. I find mine very useful.

I’ve noticed at least two posts recently stating that lens tilt controls/corrects perspective “distortion”. Many earlier posts do offer the correct instruction, that such correction is accomplished by shift ... not tilt.

Tilt controls the plane of best focus. Shift controls aim of the lens, allowing the user to aim up at a tall subject without having to tip the whole camera upward, allowing the sensor to remain parallel to the tall subject (typically a building facade).

If the max shift still doesn’t include the full subject height requiring you to tilt the camera up anyway, use of max shift has fortunately reduced the degree that you tip up the camera. That is helpful.

•=•=•=•==••=•=•=••==•=•=•=•.

FWIW, if you have tipped up the camera you have tilted the plane of best focus so it no longer perfectly coincides with the facade of a building. Use of the lens tilt will realign that plane with the facade. Again, tilt is for optimum focus and does not control perspective effects. Shift is for minimizing perspective effect.

In such examples as above, the upward shift is also called “rise”, just in case you’ve been reading “the classics” where the term is always “rise” :-)

I want to thank you for your Response concerning the Tilt shift lens.

That being said my original question was simply would the perspective be different when using a crop sensor versas a full frame sensor camera. And I believe in the few answers by people who actually answered it the answer is no.

You believe correctly.

Suppose you print such a FF image and then cut away a substantial amount of the print, like cutting an 8x12 down to about 5.5x8 inches. Clearly your scissors cannot alter the perspective of a finished paper print. Scissors have no optics and no software, right ?

I do hope it’s clear to anyone reading this that choice of sensor size is exactly the same as using scissors.

Thank you, I've used post processing To obtain the perspective I desire and know exactly what you mean obviously depending on the height of the building you do cut about 30 to 50% of the bottom off, For fun and an experiment I've rented a tilt shift lens for the week just to play with, Boy can they be expensive Id have to really need it to wanna drop 3 grand for the nikon version,

This has always been "coin of the realm" to architectural photographers, who also have other "tricks," unknown to most photographers not in that field. >Alan
