I am having problems with overexposure in my images, I ve been reading through internet some tutorials. I d like to make you
two questions about it:
1. Navigating through internet I ve found some small tutorials, that talk about if the image is overexpose and you want to fix it,
"they replace the sky with another image, using layers in photoshop" I thought this was a great idea to fix overexposure, I did it on 2 of my images
(I replace the sky), I think they look good, I also read that doing this I should adjust the brightness, curves, shadows etc, so the image looks more
real, as if the picture was shoot in real. The only problem I have is that I cant get it in fixing the edges of the image after replacing the sky, it
looks like the images color blends as I place the layer above the original image and it causes a strange edge in all the image, that I cant get rid of it.
Ok, now I have a client that needs a panorama of a farm, ranch, and the problem is that always in this area
is very cludy in these days. So I was thinking in replacing the sky, not for a sunny sky of course, but for a bright and clear sky, just in
case the image get overexposed. With your experience, Do you think it is a good idea to do this ??? Or may be I should leave the image just like it is, and
fix the brightness, aberration color, curves etc. with photoshop ???????
2. I would like you to tell me please , if these steps I do to shoot, are ok, :
a. I prepare the rotator, level tripod etc.
b. Position the camera in front of the object
c. I turn the Camera Control dial up and down in order to find the correct exposure, For example, today was a very sunny day, and the first image (0 degree) was
shoot, the Av , changed in the 3 images I shoot, Im getting guide through the " exposure level indicator" I always try to keep a (green line ) in the middle
because, too much up or down get red, and I think it is why it get overexposed.
I now found that my camera has a * AE lock button, that the manual says that this is button is effective when the contrast is too strong between the
subject and background or when a subject is backlit.
By other side: the manual also says:
pressing the shutter button halfway and pressing the * AE lock button, will lock the exposure setting.
So do you think I am doing this right to avoid overexposure or what do you think about the sky replacement in photoshop ????????
