I started my photography career as a very enthusiastic hobbyist, capturing my images on film and “slides.”
The top image started with a Kodachrome slide I took decades ago using my Nikkormat EL and 50mm f 1.4 Nikkor prime lens. Kodachrome was slow at ISO 64. The original was a couple stops under-exposed and the deck rail the bird was sitting on was rendered as black. I used a film scanner at 600dpi to digitize the slide. I then used Photoshop to add another image of wood grain, and some quick work using selection, masking and layers fixed that problem. Then exposure and color balance were adjusted . The untouched original image is shown below.
