OK, there would be a number of problems to overcome with this one, but I thought I'd throw it out there anyway.

One of my favorite things to do with a digital camera is shoot multiple image panoramics. I tend to prefer 360s, but they don't have to be.

I'm supposed to be working up a tutorial on how to make them -- maybe once I get that up, we could think about it.

(Some of the problems I foresee would be: they don't fit the image size requirements, not everybody has the software to "easily" make them, they don't fit on a screen easily at a decent size, file size could conceivably be a problem, and it would be harder to check for spot editing. I'm sure there are others.)

I am gonna have to give this a try... I have never messed with the panoramas before. Maybe I could ask you a few questions about it. I *did* attempt it one time but the first problem that I ran into was the exposure differences on each image that I wanted to stitch together. I suppose it would be best to use the same expsoure values for each image in the series rather than using point and shoot mode...

I love doing panoramas myself but I think allowing them would just create too many problems... not the least of which would be the restrictions about merging several images together (which is needed to get good results). It would also place those with certain hardware (i.e. fisheye lenses and pano heads) at a distinct advantage over those who don''t.

jmselter: yes, you should probably lock exposure (not sure about your particular model, but it should have a AE Lock option or something similiar). If you''re using PT Tools, there is also the ability to allow it to automatically correct exposure and color balance problems between your images. Most other commercial stitching software should also have this capability...

Jeff,

Your 360 panoramic shots are outstanding. Write that tutorial ;)

It should be easier for you with your DSC-F707 to do panoramics than most cameras. Your tripod socket is on the lens so you would be pivoting closer to the optical center. It helps to level your camera on a tripod, then lock it into full manual mode, and also lock your white balance setting. Sony didn't offer you many choices but you could choose the sunny or or shade, or if there was very even illumination, you could do a preset off a grey card. On each shot, overlap the previous by about 25% to allow room to stitch them together. If you don't have stitch software, and I don't think Sony included any with your camera, you can do it in Photoshop, or Photoshop Elements has a stitch mode. This post is getting a little long, but if you'd like a few tips on the software, send me a email.

A couple of other things to keep in mind is to allow enough room at the top and bottom for cropping and try to correct for pin cushion or barrel distortion on each image before you do the stitching. To help with this, try avoid taking pictures at the extreme ends of your zoom. Do all sharpening and color correcting after the photos are stiched together.

This is one of my favorite panoramics even though I think it is cropped too tight on the top and bottom and I didn't correct for the barrel distortion before I stitched it. This is the first time I've tried to include a link to a photo so there is a good chance I don't know what I am doing. You may get nothing :? )

Oops, the link doesn't work by clicking on it. I guess you will just have to cut and paste it if you want to see the image. Someday I'll have to figure out how this showing a photo business works.

i don''t know if this link will work, but this is a multi image panoramic i did without any stitching software. what makes it interesting is that i''m in the picture 5 times.

Tim... There a a couple of ways to add the links to posts... My favorite is below, but you''ll need to put [ where I put { and a ] where I use }...

{link}//www.dotphoto.com/MemViewImage.asp?AID=268926&IID=10390824{name}Text you want{/name}{/link}

I will add that link Here.


Unfortunately, your link brings me to a Login Screen :) but it''s the thought that counts.
