W/ the perspective being off between the two shots, it's going to be a lot of work. I just gave it a try and I quit because it'll take more work than it's worth IMO and still never be correct. Sorry.

yeah i gave it a try to...just too difficult...if this isn't the last time they get together on the field i wouldn't worry about it, and just re-shoot it

No way I can multi quote a response so ill try my best to answer everything from memory so to speak...

a) I've never stitched any images so I fell back to what I know or once knew: move horizontally (trucking in video/motion picture parlance) to shoot from the same plane (so a pair of negatives could be placed in a carrier side by side). I didn't know panning was the required method. Sorry...

b) I WOULD have moved back and shot from the 50yd line but I was standing on a folding chair, on the back edge of the roof of the press box in order to avoid the fence "railing" across the front edge of said press box. I did shoot from the 50yd line but I ended up cutting off 3-4 kids on both ends...

I don't expect them to meet up again now that the football season is over and marching band is effectively done for the season other than holiday parades...

Thanks for everyone's thoughts and input. Better luck next time I guess...

It looks to me as if the first image only cuts off a couple of kids at the right & has a TON of room at the left side. Didn't you see that extra room in your viewfinder? If not, then you need to pattern what you see & is included & what is not seen but included.

Using the panning technique I described would have obviated the need to step even further back - that is the point. The panoramic image is captured in multiple shots from a single point of view (more or less - there are exceptions) so that you can construct the final single-image composite. You could have stood closer and gotten all of the coverage you needed with a few shots.

Standing further back would give you less distortion in the final composite, as you project your composite into a spatial model (rectilinear versus cylindrical versus spherical, for example), but from the distance you were shooting, you would have been okay with a couple of shots centered on the 50.

Live and learn, as we all have too. Sounds like it was a frustrating shoot, which is always a bummer.

And if you look at the second image, that information is reversed. Tons of room on the right side and only a couple of kids cut off...

I DID see that extra room. I wanted to make sure I had enough "extra room" so the possible finished product didnt have kids on the extreme edge of the image...

Using the 24mm (all I had with me since i don't generally carry my wife's gear too and since I was blind sided with this request) " only cut off a couple of kids" on BOTH SIDES with NO "tons of room"...

I wanted a lot of overlap so that there would be lots of image to work with...

As others mentioned, both shots needed to be taken from the same spot. Instead you moved from one 45yd line to the other which makes this very difficult to put together.

If it was just a green grass field it would be easier but w/ the lines and numbers I think it will be next to impossible to line up, correct rotation, etc to make it look good.

could you post the one from the 50yd line...it may not help to line them all up...but it may be worth a shot

attached...

actually looking at this again (for the 37th time) it looks like im ONLY LOSING the male display flag guy on the far left! you can JUST SEE his foot and leg...

i need to move him to the center a little bit then figure out a way to add more image "space" on the edges so when its printed (director likes BIG poster size prints) they will fit inside any framing he does...

yep. i know now, i should have panned vs trucked...

i was on the roof of the press box, on the phone with a booster on the field, trying to get the director to make some slight adjustments. it was about 50o and the wind was blowing so the display flags had to ditch coats and sweatshirts and i jumped on the shoot. i had told him before they got on the field that they needed to stay inside the 30yd lines but it was HIS way or his way, so i shot it how HE wanted it...

like i said, if i had known ahead of time, a) they wanted a formation on the field and b) they picked THAT formation (size) i would have brought my wifes Rebel and her 10-22 ultra-wide. i have no reason to carry that extra crap around with me!

thanks again everyone!

I understand your constraints and you're to nice to tell him to pound salt. I would have done just that...either he helps make it work or he gets nothing. I've been in this exact situation w/ the school my wife works for and have walked away from "helping out" since I wasn't able to do what the irrational person wanted done. He should have asked you earlier and that is on him.

I reckon you might be able to salvage something using that 50 yard line image as the basis, no-one really looks closely at hte edges of an image anyway.

It won't be a "stitching" job though, it'll be a blending of layers in PS with some skew and other tweaks.

Not at home atm, but I'm have a play later tonight if I remember

I don't think you want to stitch the photos. All you need is to copy and paste the left or right part on to the other.
I think it should be pretty simple. I shoot high school bands all the time. For some 20+ years now. A director will never change his program for the photographer!

This is what I think of when you say 'stitch' a photo(s).

Isn't that what stitching does?

Apart from the fact that the grid lines are running in opposite directions so nothing will line up.


Football is a very simple game. Twenty-two players chase a ball and Germany always win.

This is what I think of when you say 'stitch' a photo(s).

As an aside, I shot all of the portraits for them this year. I had everyone but FOUR drum majors. I told the director, that since it takes about 30-45 minutes to drag all my gear in (to the room at the stadium where i was doing the portraits), set it up and verify it all, I would shoot them early on (before ANY OTHER band stuff) at the last game of the season...

I wasn't able to get into the room soon enough soni told the drum majors, right after pre-game. They all acknowledged that. I told the director of my decision and he wanted me to just bring all my stuff to the school next month and try to set something up before their marching band concert in the gym!

I told him "Nope. I've got everything here, it's set up and ready to go, so they will be down (to the room) after they get the band back into the stands."

I wasn't going to go through all that nonsense again...

Like you DagoImaging, I'm done trying to help. I've got one shot he wants printed, I'm waiting for dimensions on, and they can fend for themselves or get the OTHER GUY who wants to be their shooter, to handle it...

Just for your future reference, remember the suggestions made here. Stay in one position and just pivot. I only overlap maybe one third. But more importantly I sure something of significance is in each two photos that are going to be right next to each other. You don't need to worry about staying level, coverage is what is important. The software will figure out all the points to merge regardless of your camera orientation. You can use any lens.

I use Microsoft ICE. Its really good. Photomerge in PS totally rejected your photos. ICE made a great attempt to merge, but just completely deleted the 40 yard line and the people in dark uniforms (because of the changed perspective).

Remember those two points

- pivot
- coverage
