color and pan stitching

[THaNaToZ]

After reading the most recent thread on stitching posted, I had a couple of questions I wanted to ask.
My old P&S camera would allow me to do a color stitch (say focus on red and grey out the rest) and pan stitch.
Are these options available somewhere in Canon 70D?
I've read through the manual and played with the menu but nothing sticks out to me.

I assume the answer is no and the pan stitch has to be done in PP.
I've seen a few recent pictures on here of one color popping in the picture and the rest greyed.

If its not possible, what's the recommendations on trying to achieve these. I assume tripod, which I have, for the pan.

Hi Ankit,

I'm assuming you're trying to "stitch" together a number of photographs to achieve a panorama?

This can be done by some cameras but most people do this in post.

And for the other subject I can only think you mean selective colouring. Again, some cameras are able to this but, again most people do this in post, as this gives more control.

If you give us a bit more detail, we can be a bit more helpful.

If your editor has layers and the ability to reduce the density of individual layer you are well away hand holding panoramic stitches so long you operate the camera as if it was on a tripod. The less it is the more work in editing

To register two layers you reduce the density of the top layer until you can see enough detail in the lower layer to make the register ... repeat the process for other layers in turn. You will also need to increase 'canvas size' of one layer to allow room for the extra imagery being added to it. A modern stitch programme may do all this automatically for you, but I prefer to have control over the process.

I think you're thinking of a different process, it's not stitching to make only one particular set of color values to take on the particular color in the image. In my set of hardware and software, it can't be done in the camera. I need some software and a computer to do that.

If I understand what you're talking about, it's a little bit like the last shot in Schindler's List where a little girl in a pink coat carrying a rose is in color and the whole rest of the scene is B/W tones In fact, the whole movie except for this shot is completely B/W.

If I were doing something like that, I'd first take a picture in color (a camera process). Then, I'd draw a mask around the part I wanted to preserve in color + second mask around the edge of the picture. In the software I use, I'd then choose to invert the masks which would have the effect of protecting the color in the area I wanted to be in color. I'd then select the inverted masked area to be changed to shades of gray. Finally, I'd click on an area outside the images and do a marquee select to include the entire image and save the entire image back to a new file on my disk drive.

The other thing you could be talking about is changing the color cast of the whole image to be change that would be similar to creating a sepia or a B/W of the whole image to be in those particular colors. I'd do that in a Hue-Brightness-Saturation color shifter. This is often done used when a person has "odd" light happen to him or her. And, the photographer most like wants the odd color to go away! Think about a place, like Las Vegas, where lots of those lights may be pink or green or neon blue, etc. and you may not want a person in your photograph to come up neon blue!

Hope this helps.
