Is Panorama no-no on DPC? - DPChallenge Forums

Canon EF 24-70mm f/2.8L USM

There were seven images lying on my machine which I took last year in Vail,CO. Finally I stitched them together for 11x2 (11000x2000 Pixels approx) panorama. Since this is my first attempt with Panorama, I was thought of uploading it to DPC and getting comments for improvement. But it seems like due to restriction on 640 pixels on longer side, my work is hardly visible.

- Is panorama strictly no-no on DPC?
- Is there any way of making this visible (with decent) size to DPCers?

Anyway, if you still find it worth commenting (with current size)- please do :)

i think you can uplaod whatever you want into your portfolio. but on a challenge yes 640 is your max, and it can only have one photo.

I posted something x 2048 pixels photo. But the visible one is downsized to 640 pixels.

yep the biggest you can do it is 640 pixels like said before............. but if you have it on another site where you can post it bigger or even the original size do that and then just post the link in the descriptions field of your pano here.

Thats what I did for my pano's

Your best bet at this point is to post it to some other photo-hosting site (e.g. pBase or SmugMug) or your own site/space and then post a link to it here.

I use pBase myself, and they make it fairly easy to post a thumbnail image here with a link back to the full-sized image at their site. The only disadvantage is that people can't enter comments which stay here at DPC -- perhaps you can also post a small version here just for that purpose. You can even put the link to the full-size image in the image's comment thread, which works just like the forums ... something like:

Hi, I think your photo is awesome! I'm just getting interested in doing these myself and I was wondering if you would share how you did it? Just lined them up in Photoshop, or did you use some extra software, or...

Thanks!

I'm quite a fan of Panoramics myself, and I have been looking for a good site that allows large files and wide files specifically for that. I found a couple that allow big pictures, but I haven't played with it for so long, I've forgotten what they were. Worth a look around though.

I think the max pixels was like 6400 on one side or 8000 total on one picture site. I forget.

I need to work on my general photography first...

There is nothing wrong with panoramas, it is the usage of more than one image to make it that is a no-no.

DPC limits the size of images you can upload so you cannot show panoramas decently. That is why I display mine here: Steve's Panorama Experiments

My advice:
1-Always use a tripod and shoot in portrait orientation

2-Overlap your images about 25-30%\

3-Shoot as quickly as possible with all the same camera settings, including white balance

4-Review your merged panoramas VERY closely, you will have to do blending and fix spots with bad merges

5-Try making panoramas with more than one horizontal row of images to attain greater height.

I did it with the software which came with my camera (Olympus Master). Simply clicked 7 photos (hand held) at different angles with slight overlap and stiched them in software. Ah yes- there is option of panorama mode in my camera to assist the overlap. Anyway, this is my first and only attempt with Panorama, so I'm not the right person on this topic :)

Thanks, Steve! I have another question - How do you get your panoramas printed? Do you break it into parts and stitch the prints? Or do you use padding around image and then cut it off from final print (which seems to be awful waste of paper and money)?

One of my favorite panos ever is "Paris by Night" - not sure who the author is but the stiching is seamless. It is a large image (14929x526) and may take a while to download - but is worth the wait. Of course it looks tiny in IE so you may want to download it and take a look at the detail.

Another very similar version of Paris by Night by the same photographer is found here:

Older versions of Canon's Photostitch did not allow you to 'nudge' your merges. The newer version that came with my S2 IS allows a lot more flexibility by allowing nudging.

I haven't found a way to merge more than 1 row so far though. What software do you use? I am not familiar with how to use PS to do this. I have PS 7.0.

What focal lengths do you guys usually shoot to do Pano's?

I plan to get a 28-75 soon (new camera tapped my $$ out), and I imagine that this should cover the majority of useful lengths... More telephoto seems to make hyperfocus a bit more challenging...

If anyone is interested, I made a thread with some in-depth tips on how to modify a tripod with a pano-oriented setup with less outlay in chash. Do a forum search in Hardware for eschelar, pano, bank.

I don't have anything sophisticated... I just mount my camera in portrait orientation on a standard tripod and overlap images about the amount Adobe recommends. My images have been experimental up to now but I want to do some good high megapixel panoramas.

Photoshop CS2's built-in "Photomerge" function is used to put the images together. I'm guessing there are probably better 3rd party tools but I don't have one. Photomerge has some trouble deciding how to merge images, but you can drag the images around to get them into the correct positions when Photomerge can't figure it out. Then I have to do some blending and fixup where the images don't merge properly.

Nothing special for focal lengths either. Obviously, the larger the focal length the more images you can use and the higher the megapixel density of the result. Of course, there is more work putting them together.

Two larger ones I've put together so far is a 180 degree 9 image single row horizontal and a 12 and a 15 image two horizontal row ones.

So CS2 allows to merge in arbitrary alignments? or how does it work?

Are you taking pictures based on measurements? How do you align a second row?

Sorry if this sounds dumb, but I am still pretty new at this myself...

Huge Panorama. While in Iraq a few months ago, I completed my very first Panoramic photo. My goal was to attempt a 360 degree view, but didnt make it that far. I would say I am close to 270+.
Along with this huge Panorama, comes a huge problem...How can I post it here so all of you can look at it and give advice?
HUGE PAN = 16568 X 616
The subject of the photo is Al Asad, Airbase in Al Anbar Provance, Iraq.
Thanks..(pd)

I'm working on my first 3 row panorama...
It is made with 30 individual frames and took me more than half a day to merge. I took it with Kirbic a few weeks back. It is a little bigger that 12,000 X 6,000 pixels making it about a 75 megapixel image. That is big! The file itself is 240 megabytes as an unprocessed 8-bit .tiff graphic. At 300dpi will be just under 4 feet wide by 2 feet tall without upscaling. It is put together but needs blending and post processing before it will be ready for show.

CS2's "Photomerge" will take a selected group of open images and attempt to put them together when asked. Often times it does a pretty good job, but not always. If it can't figure out how to place an image it leaves it at the top and tells you it can't be placed, but you can fairly easily merge it by hand with a few tries.

CS2 then allows you to drag and drop images from the top or reposition existing onces for a better fit. It allows regular or perspective merges. I've only used regular.

I don't do any special measuring, but I do make a "hand" scan to get a general idea how I want to position my camera and where my rows are going to be before starting. I start taking pictures on the highest row and work my way down. I take pictures left to right for the first row, position downward, then go from right to left, then downward and then back to left to right again. This is how I maintain proper overlaping.

Alignment is achieved visually while taking the pictures. There should be about a 30% overlap of frames when doing a horizontal row and a 30% overlap on each row. After each picture I locate something in the field of view about 30% in from the other side of the frame then reposition the camera to put the reference object at the edge of my field of view for the next picture. When the first row is finished I position the camera downward to something about 30% up from the bottom then take pictures going in the opposite direction.

Woah. That sounds insane! what an awesome picture!

I'd love to see a pic of your setup. Do you tilt your camera up to take the different rows? If so, do you tilt around the optical center of the lens? Doing so seems to me like it would skew the perspective ratio as you moved upwards from level to the horizon... Other obstacles I can see from this far would be in the skewed plane of rotation at the center axis, causing extreme left and right to dip and overlap more.

This might not be an issue if you do all of the positioning by hand.

I'd love to see that picture you have done though. NICE!
