Just Google "Stitching Panoramic" will do.

[Fragnatic]

the term, used in photoshop for stitching images into a pano, is called photomerge.
here's a tutorial: http://www.photoshopsupport.com/tuto...hotomerge.html

u can search the term "photomerge" in ur photoshop help section.
the button for photomerge in photoshop is located in File > Automate > Photomerge.

Hi twinkleS,

Here is one on Luminous-Landscape:

http://www.luminous-landscape.com/tu...titching.shtml

However, I highly recommend using Hugin instead of PS to stitch your panorama. It's free and has a lot more features designed for stitching panorama, and I use it exclusively to stitch my own panorama:

http://hugin.sourceforge.net/

You'll need to download and install these files:
Hugin (the panoramic tool itself) - http://downloads.sourceforge.net/hug...8&big_mirror=0
Autopano (automatic stitching recognition, Hugin's helper) - http://autopano.kolor.com/autopano_v103.zip
Smartblend (automatic blending, Hugin's helper) - http://wiki.panotools.org/wiki/image...lend_1_2_5.zip

Here are the tutorials on how to use it: http://hugin.sourceforge.net/tutorials/index.shtml

I'll post some sample pano stitched by Hugin tonight.

If you decide to use Hugin and are stuck, drop me a note and I'll be glad to help you.

Cheers.

thanks catchlights for providing the correct term to google. thanks alot!!! =)

[twinkleS]

thanks Fragnatic,

for the detailed instructions. i will go try it out. thanks for the tutorial too. it sure helps!

[twinkleS]

hi Ziploc!

thanks for providing so many useful information. seems like Hugin has alot to play with but i total green to it. but i will still download it and test it out!

i will be looking forward on ur pano using Hugin!

*cheers!!!* thank you once again...

[ziploc]

Arh. Just when I thought I could eat snake tonight...

Anyway, here is one from my trekking trip to Sichuan China last year. It is a 360 degree pano made up of a total of 27 frames, taken hand held on the summit and stitched together with Hugin version 0.7. There are actually 2 guys in the pic, see if you could find them.



Cheers.

[twinkleS]

wahaha. didnt expect you to post up by tonight la...
hehe... but really glad to see it.. so flawless!
up to date i have nv try to stich a pano before.
i guess im gonna work on it tonight. i hope it will be as flawless too! =P

hum... 2 guys... izzit somewhere right? lol.

btw, what do you meant by 360degree and 27 frames? 27 frames=27pics??

thanks alot~!!!

[Fragnatic]

yep. 360 degrees means 1 full round.
27 frames means 27 pics.

take 1 pic, turn a bit. make sure the view of the nxt pic overlaps the 1 one by maybe 20-30%? then bit by bit turn until u fae the original facing lor.

[twinkleS]

waha. thats super chimology leh...

i will go read it up. and try it out. wish me luck~~!!!

i think i will start by stiching 3 pics or so. 27 too tedious! LOL

[ziploc]

360 degree means that the pano covers 360 degree view, the entire view of the scene. If you notice, the left edge actually joins back to the right edge. Yup 27 frames means the pano is made from 27 pics.

A few tips on shooting pano:

1) This is very important: always remember to lock exposure, meaning either switch to manual mode (which I prefer), or use AE lock. To find out the aperture and shutter speed setting, I would first set the camera to aperture priority mode and select an aperture, turn one round with the camera and take note of the metered exposure (in this case the shutter speed). The shutter speed will be higher at the brighter sky, and lower at the darker side. Choose an adequate shutter speed base either on the exposure of the main subject (which in this case the peak) or average of the noted shutter speed range. Then set the camera to manual mode and set the aperture and shutter (or lock AE at the desire setting). The reason for doing this is to avoid having some frames with darker while others with brighter exposure, which will cause a lot of stitching problems. Using manual WB will also be useful.

2) Select a focal length that has less distortion (this is dependent on your lens). This will also help in avoiding stitching problem later. However, Hugin has in built algorithm that is smart enough to handle many lens distortions so this is not a great issue.

3) If at all possible, use a tripod. If not, hold the camera steady and turn with your lower body and not your upper body. You can do a practice turn before shooting. Make sure there are enough overlap on each frame to the previous one.

Hugin v0.7 is actually pretty easy to use with it's new "assistant" feature. Just follow the steps and click the 1, 2, 3 buttons and you're done. But of course if you want to fine tune you'll need to understand the program better by reading through the tutorials.

Cheers and have fun.

Haha ya starting with 3 pics is a good idea.

[twinkleS]

from what you written above,

i have understand that to create a pano, i have to take pictures in sequence and in order and of cause lighting etc.

but now, can i stich up unrealated pictures together and produce a pano with flawless lines too?

pls correct me if im wrong. pardon me for asking so much. =P

Cheers.

Don't think so. The pics must be in sequence and have about 25-30% overlapping with the pics next to it. If you really want to play, I guess you could take 3 overlapping frames with flash in your room, or if you have a tripod, go outside and shoot a few overlapping frames of HDB flats.

[ziploc]

To give you an idea, here are 3 frames that made up the peak near the center:

[twinkleS]

ahh.. i got what you meant already. hehe...

at first i thought must shoot correctly at the cutting point.

now that you share about over lapping. phew!

i will give it a try by taking my surrounding. haha...

if sucessful i will post up.

thank you many many!!!

lotsa ,
