Just a little demonstration as to what can be done with a coloured photograph using a photo editing program. I used PhotoShop in this case. Of course, if you camera has the capability of changing the colour of the photo as you snap the image, you can use that, too! Mine does, but I usually like to take the photo in colour first, then edit it. The photo demonstrated below is of a Daffodil I found along a bike trail.
This photograph of an iron wagon wheel was originally taken using the Sepia setting on my camera. I thought I would look really nice with that alone. It did, but it needed something more. So, I aged this photo using several different techniques in PhotoShop and this is the final result. Kind of an old looking photograph, but taken just yesterday.
