Most of my pictures are lacking the correct alignment: vertical lines are not perfectly vertical and horizontal lines are not perfectly horizontal.

Actually, there is a better way to describe the problem: my pictures show a SLIGHT ROTATION TO THE LEFT or counterclockwise. In fact, if I want to correct the problem, I need to use any software for editing pictures and use the "fine rotation" function in the opposite direction,.

It must be the way I try to do the alignment while I am shooting. I am doing something wrong and I don't know what it is.

How to get a correct alignment? What am I doing wrong?

Maybe I am trying to align the object with the edges of the viewfinder. Is there any way to have like a grid or at least one vertical line in the center of the viewfinder that I can use as a guide?

Anyone else has this problem? I don't thing that it has anything to do with the camera but with me.

I tried to attach one of my pictures so that you can see what I am trying to explain but each time I am getting a "runtime error" (this is a new PC).

Hi Marcial.

From the other thread, I know you are using a D90.

I believe what you want is the Viewfinder Grid Display.
Check page 181 of your manual; it seems to be the d2: option of your menu. I haven't used it as yet.

And, to help with the images you have already, check
page 221. It should allow you to rotate a copy of your original
image in .025 degree increments, up to five degrees in total.
And, again, I haven't tried it.

Hope this helps.

Terry.

Terry, you helped me a lot! Yes, the option was there just as you said it. Now I got the grid I wanted in my viewfinder.

As for editing pictures in the camera, you are absolutely correct again!

Thanks again,

Hello Marcial,

I use also a bubble level for the shoe mount. It helps a lot. By the way, do not understand why the grid has 3 lines instead of 2.

Regards from Spain!

Hi Rdolz,

Yes, the grid has 3 vertical lines and 3 horizontal lines but a friend who also have a Nikon just told me that we can change the number of lines. I didn't try it though.

Now, talking about the perfect level for the camera on a tripod and the bubble, I am not sure if that would resolve the problem. The lens play tricks on us and sometimes we need to place the camera in an odd position (not perfectly leveled) just to compensate the distorsion in the center of the viewfinder, so that at least the lines in the center are vertical and horizontal

This is one example of the problem with the alignment or pictures with slight counterclockwise rotation.

It's possible that I was unconsciously aligning the building on the left with the left edge of the viewfinder.

Hi,

Could it be lens distortion, is it a 18-105 vr lens you have.

Depending on what I'm photographing mine throws the vertical lines off but I fix it in post.

All the best

Stevie, you are right, I was using 10-105 VR in those pictures!

I was on vacation in Paris so I didn't want to carry all other lenses with me.

With wide angles there will always be distorsion but it seems that I tend to align on the left.

Any other thoughts will be appreciated.

There are lens aberrations such as pin cushion and barrel distortion, but this does not appear to be one of them.

Another possibility (especially if it occurs with more than one lens) is that there is a misalignment somewhere. Most likely with the focus screen and/or mirror. Have you tried setting your camera on a tripod and using a bubble level to make sure the camera is level? That will tell you if it's a mirror/focus screen alignment problem or a remote possibility of the sensor being out of alignment.

Hi Pete,

No, I haven't used my D90 with a bubble-level tripod.

I don't mean to disagree with any of these valuable opinions that you all are giving me, but the more I think of the problem, based on the opinions I am collecting here, the more I believe that this problem has to do with the way I hold he camera looking for a reference line on the left.

Now that I have a grid on the viewfinder, I will try the center alignment, particularly when I am shooting at a wide angle.

Let me try that first, and if the problem persists, I will to the bubble level.

Thanks a million, again.

Yes - from the example posted above, I think that is the most likely explanation. With this type of shot, finding a horizontal edge parallel to the camera sensor somewhere in the scene, and aligning with that, can be the most reliable method. Using a vertical edge can prove troublesome, especially if you're pointing the camera at a slight angle up or down.

Brian, so you recommend a horizontal line as a reference instead. I will try the horizontal edge before anything else.

Thanks a lot again.

I have the same problem with my D50, and I am nearly certain it is me, tilting the camera ever so slightly. Some are good, and others are tilted in varying small degrees.
