How to tilt easel under enlarger without a darkroom?

When a building is tall and you are close to it and take a wide angle shot, the perspective goes weird and it looks like the building is tipping over. In a darkroom, I could simply tilt the easel that holds the undeveloped print paper to compensate. So, I have Photoshop and Lightroom and aren't very good at either one, although I have used PS for many years to create web images, but I have not done too much post processing of RAW images other than to adjust brightness, contrast, or simple stuff like that. I just want the building to stand up straight.
Thanks in advance...

Suggest you start this topic in the Post Processing section. Some good, friendly folks over there that can help you.

Perspective control in post processing can somewhat correct what was done with view camera image management techniques or tilting of the enlarger easel.
Attached is a quick edit.

In Photoshop....and this will depend on what version you might have installed...mine is Photoshop CC 2019, YMMV...(Your Mileage May Vary!)...but in these later versions there are a LOT of 'perspective' tools, look under the "Edit" tab, about half-way down there should be 3 options, Transform, Free Transform and Perspective Warp. They all do somewhat similar functions...some of them require that you have the image 'Selected'.... I have not used ALL of the 'tools' available in them, but basically you click on your image, say at the 4 corners of a building, press Enter, then drag those any of those points to a place where things look "right" to you... This is a very simplified description of these amazing tools, best thing is to open your 'problem image' and play around with it.... Hope this helps... What E.L. Shapiro did is a very good example of the technique.
The "Perspective Warp" takes this to the next level, in that it can produce an image that looks as if the camera was shifted around the corner of a building...LOTS of fun working with that one....[G]

It will help you if you add a grid to the image prior to Transform / Skew/ Perspective /etc is selected. That will give lines to help straighten things up.

Nikon has a program in retouch menu that can help. But, you did not list your camera. I am assuming you shoot Nikon, or, wish you did.

The best you can do from the ground with your point and shoot Nikon is keep it parallel with the building, zoom out so you include the top of the building, and crop out the foreground. As you can see, software manipulation isn't much better. If you cannot elevate your position to the height of the center of the building, best to use a shift lens.

DXO Perspective control has a lot of tools. I believe you can download a trial.

In LightRoom, you use the "Upright" tool under the "Transform" tab. Uncorrected vertical perspective bothers the heck out of me. Often, the first adjustment I make is the vertical correction. "AUTO" works very well in "upright". When taking the picture, use a slightly wider angle lens than you might normally because you will lose part of the image to cropping.
My Olympus has an anti-keystoning feature that will take care of it in camera, but the resulting image is a jpeg (you will still have the raw as well).
PS also has perspective control hidden somewhere in a drop down menu. Check help for that. It is likely in every editing package available now since all producers want to be competitive with Adobe.
If you want to take care of it in camera, there are perspective control (tilt-shift) lenses available, but not for all brands and expensive.

I agree, but overcorrected vertical perspective can also be annoying.
My first impression of Mr. Shapiro's version of the corrected building was that it was overcorrected. If I measure the distance of the top and bottom of the building from the margins of the photo I see that it is corrected to the point where the edges of the building are parallel to the margins of the image.
However, it is clear from the perspective that the viewer is looking upwards at the building. Consequently, making the edges of the building parallel to the margins gives me the impression that the building was constructed with the top wider than the base. The original does look like it needs to be corrected, but if I were doing the correction I would do some, but not as much as shown.
Here is my version, which was done in Lightroom. The top has been pushed wider, but not to the point where the sides are parallel to the margins. It still gives some impression that you are looking upwards at the building.

Some folk advocate leaving a small amount of lean back /distortion, rather than 100% perpendicular upright corrections. For me, I usually consider how the 'Corrections' look.

The internet is full of tutorials, both written and video, of how to do specific actions with PS and LR. If you are interested in a more structured learning environment, see if your local library system offers free access to lynda.com via their e-resources....

You will always find folks on UHH, whether in main discussion section or Post Processing, who will edit for you, but you have very powerful software and exceptional online resources to help when you're stuck.

Agree, full correction of the convergence does add a different visual distortion. Your adjustment retains just enough convergence to make the image reflect what one’s eye sees.

I agree that the RHS is over-corrected, but Mr. Shapiro did add that it was a 'quick' adjustment.
