Stitching multiple linear photos

 


shenyl
Anyone can suggest a stitching tool for WIN, that will enable me to get the photos into one complete picture. I lost my software for my Canon camera - that does this.

Is there a freeware I can use - previously has tried Hugin v7, but seem unfamiliar now, as I tried it again.

Please advice, thanks.

do you mean make a collage and that make a complete picture?
if so you can easily do that in photoshop.
shenyl
My understanding of collage picture is one make of multiple shots, but the overlapping areas are not merged into one big stitched picture.

Does photoshop perform stitching (joining several overlapping shots) to create a wide angled shot of the landscape?

Sorry, more info needed. Anyway, I do not have the expensive photoshop software installed.

Yes, I use that function myself whenever I need to make a panorama.
shenyl
That's great that the photoshop software is able to do the stitching of multiple photos.

Thanks for assuring, I will have to dig my older CDs to find if I do have the
photoshop (express) software, that often comes with digital cameras or DV cameras.

Thanks.

Photoshop has an outomated photomerge feature that will allow you to select the relevant photos and creat e a panoramic from them - it lines them up for you and everything.

The automated aligned them all and merge them is definitely what I am hoping to get. But as I mentioned, Photoshop is not cheap. I could find my old Photoshop software (from previous digital video cameras, digital cameras).

Just curios, photos that have slightly different tones (darker, the next one taken slightly lighter), does Photoshop also able to resolve them?

I have tried a Open Source program, similar to Hugin.exe that even takes care of the tones - it was a development project by someone, but I lost that program too (more than a year ago).

Thanks, and do feedback on the merging of different tones/shades.

Finally I found the associated program PTstitcher.exe from PanaTools and also the proper way to use Hugin 0.7.
After more than a day's work, I managed to figure out how to use these 2 freeware to stitch a panaroma view from my 4 photos.

Firstly, here is the URLs to my 4 unstitched images, the images are all resized using Faststone resizer (another great freeware).

Note to use Hugin properly, use the digital images with the EXIF info INTACT!
Else the pictures will be distorted when they are joined.

Load the images - that is easy, but don't auto joined them.

Oh there is a limit for number of words here. Refers to my Blog

"PhotoStitch - Create panoramic shots from multiple images with Canon’s PhotoStitch software. You can combine up to 26 shots quickly and easily. Simply arrange your sequence on screen and join them up with a mouse click to create dramatic-looking wide-format images and posters."

If you will look "hard enough" (I think you know what I mean) maybe you will re-find it. Smile
My personal opinion - BEST tool on the market - even Adobe Photoshop cannot compete with it. Smile

Brighten/darken as required before you use stitching/merging.
shenyl
Thanks, but once you brighten or darken your images, can you be sure the other images that are to be merged will all have the same lighting conditions - the best effort will still creates individual images of different shades.

Then when you merge them - there is still the effect of different tones from different photo shots.

Moreover, for some stitching software - this editing effect most prpbably remove the EXIF info - like focus lenght, etc. And the stitching software will not work properly.

The best solution is that the stitching software also render the lightning adjustment in the process of stitching them together. That is why I recommend Hugin and PTStitcher software.

Need to try out the Cannon software, before I can comment. Please note that many software many be using the PanaTools (commercially OEM versions).

With regards.

Thats why you do it before you put them through the stiching software, I have found it easier than trying to adjust half a picture afterwards, Im not sure how good any stitching/merging software is compared to doing it manually (so to speak), I have allways found that individual touch much more result pleasing.

I guess you must be pretty good to manage the individual photos, to ensure that their lighting and gamma settings matches those photos next to each other.

Gamma setting deals with the 3 channels of CNY colors. Personally I find it hard to do that.

PTStitcher.exe working with Hugin.exe - examines the Gamma settings of adjacent photos and adjust them so that they matches very closely with each other. The resulting stitch is not flawless but often much better than human judgement used on individual shots.

I hope this clarify my earlier explanation. With regards.

If you take the shots at the same time, locking the settings, shooting in portrait (vertical) and overlapping the shots slightly you generally get photos that need litte if any adjustments with regard to the one next to it , if you have taken the shots and making a panorama of them is an after thought you more than likely will allways have a flawed outcome using any automated software.
As with all things photoshop "theres more than one way to skin a cat", and I know exactly what you mean, but I have never found a "stitcher/merger" that quite cuts it for me, theres allways some tidying up to do ,and I have personally found that using individual tools and a few layers much more result pleasing than any auto stitcher/merger I have come across.
When you do find your stitcher please post the results it would be interesting to see Smile , I have not looked at this type of automated software for quite a while, maybe things have improved greatly since last I did.
shenyl
Yes, the conditions do not changes, but using automatic Digital camera for quick shots, often resulting in the settings been changed by the auto mode.

Agreed if you set all settings manually and if you camera allows that (Auto Exposure and Auto Aperture settings and shutter speed settings).

Most often the auto mode kicks in and the example I have in Facebook shows the effect.

4 shots with proper overlapping areas taken in sequence.

1 stitched with Hugin and applied with PTStitcher (for gamma and lighting corrections).

1 stitched with individual shots adjustment (the best I could)
http://www.facebook.com/photo.php?pid=411682&l=32422&id=684027744
1 stitched final result with proper trimming off dark edges.

I do hope it gives some explanation to my earlier note. Hope ot gives some confidence to use
Hugin version 7 and PTstitcher.exe - some adjusting and testing is needed to use
these free tools effectively.
With best regards

Thanks for putting your work up to view Smile , they are a little small though.
