Hi I know there are a fair few cameras which record pitch and yaw of the camera when they take a photograph.

Does anyone know a tool that will read that data and level a photograph, I'm editing and cropping a bunch not taken by me and this is getting tedious.

You might enter

auto leveling photographs in post processing

in google. There are a number of hits, but I didn't really check any of the to see if they mention add ons, etc.

Thanks Bob unfortunately it tends to lead to links for auto levels for images rather than rotation.

Pentax has a nice twist to their camera's autoleveling because of the floating sensor used because of ibis the camera can twist the sensor a couple of degrees to compensate when the photographer is a bit off holding the camera level. I thought that was me getting it right :) turns out my camera has been helping me out all along. Unfortunately these are from a Nikon...

Sorry, blackest. It was a hurried search while some software was compiling. I should have thought of levels, as opposed to level when I searched.

was looking and https://github.com/DaveBurns/ExifMeta should bring up metdata so you can get the angle from the exif data.

A hot shoe level! You have to do the leveling! Well, I just saw you doing it in editing, looks like you have to tough it out (as batch processing would not work in this case)!

If you are not using the measure tool (ruler) in PS, this might help.

Select the tool and draw a line along a vertical or horizontal line. Next, go to rotate/arbitrary. The correct angle will be applied to level the image.

just finished around 130 photo's levelled and processed. Now camera's know when they are at a tilt there should be a way of working with that data.

manually levelling is ... horrible!

Adobe Lightroom 6/CC has an auto leveling feature. I don't know if it uses pitch & yaw data recorded by the camera or if it somehow recognizes and utilizes vertical and horizontal lines in the image itself.

I don't use that feature in LR... it's too slow and isn't all that consistent or accurate. I just straighten things manually and by eye. LR can be set up to display a grid in the "crop" mode. That really helps making those types of adjustments manually. Yes, it's tedious... especially after a long day's shoot when I've got 3000 or 4000 images to edit. But, it would take a whole heck of a lot longer to use the auto feature. Besides, a perfectly "leveled" camera isn't always "right".

I use similar leveling bases on two of my Gitzo tripods. They add about 1 lb. to the weight of the tripod, but are worth it to me because they're a real time-saver, especially when I'm using a gimbal adapter or head.

Without the leveling base, you can achieve the same thing adjusting the tripod leg length... But that's a rather fussy, time consuming, trial-and-error process that you need to repeat each and every time you move the tripod. With a leveling base, you just need to get close with the leg adjustments, then use the leveler to fine tune things. And often when you move the tripod all that's needed is a quick re-adjustment with the leveler.

Among other things that can help make for more accurately leveled photos... I find a grid display in the viewfinder makes me a lot more accurate. My cameras have it on demand, but in older models with interchangeable focus screens I always got and installed the type with the grid engraved. It especially seems to help when hand-holding the camera and shooting fast.

And, yes, those little bubble levels that fit into the hot shoe can help too.... Mostly for slower shooting conditions such as landscape or architecture shots done with a tripod. For cameras' that lack a hot shoe, there are similar that simply lay on a flat surface, as well as magnetic mount (if you can't find those for photography, similar are sold for gunsmiths installing rifle scopes and high precision marksmen using them). I've used various bubble levels on medium format and large format film cameras, in particular. My current and more recent DSLRs have an electronic level built in... though I gotta admit I don't use it much.

Despite Alan's thought about LR's slowness, which doesn't affect me, the auto and manual leveling and straitening as well as lens correction capabilities has been a boon for me. Since my "eye" is certainly less craft-worthy than Alan's, that same eye is the usual cause for my NEED to straighten in the first place. It has saved a number of otherwise acceptable images for me.

Try it, I hope you'll like it. It's worth at least $2/mo. That's 20% of the CC cost.

...this is the *way!* I use LR also, and do thousands of shots for a "job," I've found that it really doesn't take all that much time. I have the crop feature macro data installed on my (gaming) mouse, hit the button, do the crop/straighten (as above, using the grid almost exclusively) then do the other necessary edits, save (also a button on the mouse) and, bam, on to the next. I'm a carpenter and used to straight and level for a living...trying to level a tiny camera, I think, is ludicrous. I get it most of the time by eye, or rock the boat a bit in LR...

If you are using LR, you can use the auto leveling feature under the Lens Correction tab of the Develop panel. I take publicity photos for a local symphony and they have an art show before the performance that features local artists. I have to quickly round up the artists and match them with their works of art and photograph them together. Since I am moving around to take the shots, they are not always level, or I have to shoot at an angle to eliminate reflections if there is glass in the frame. The auto level in LR works great to correct leveling errors. While LR occasionally comes up with some goofy leveling correction (like 45 degrees off), it still works pretty well most of the time. I have a Develop Setting specific to the symphony photos that I use to make the leveling corrections when importing the photos from the performances and then manually correct the few that LR goofed on. I am amazed how much a correction that is probably less that half a degree greatly improved the appearance of the photos. Now I always try leveling corrections for most of my photos to see if it improves on the final picture.

LR also has an auto button above the angle tool that is found as part of the crop too. I use it on occasion but prefer to use the corrections available under Lens Corrections because it also provides vertical and full corrections for those situations where I have to shoot a bit to the side in order to avoid reflections.

I have to shoot level and vertical. I use a Manfroto 405 on a tripod and polish in LR. No big deal.
