| Hey everyone I need a little help and I am kind of in a hurry. I have made my homemade landscape and I can't seem to get the right DOP either I focus on the foreground and the background is too out of focus or I focus on the background and the foreground is out of focus is there anyway around this on such a small scale. Or is it legal to take to shots of the same image one with the foreground in focus and one with the background in focus and merge them together? Thanks I am in a hurry since my homemade landscape has will be disintegrating shortly. ~jenn~ |

| Push your aperture as low as it will go (i.e. if you've got f/32 on that lens, then set it to that) - Then use appropriate lighting, shutter speed and ISO to make up for the 'lost' light. |

You are referring to depth of field, right? Just to make sure.
DOP?
If so. Close down your aperture. Or.
You could focus about 1/3 into the composition, usually this helps DOF tremendously. It's called using the hyper focal distance although this is a liberal way to apply it. Again, keep your aperture closed as much as possible.

You can take several shots and combine in PS . Advance editing allows you to do that to increase DOF. As long as the scene doesn't change.
Shooting at f 32 might soften your image. Not sure what lens you are using but shooting at the extreme settings of your lens might compromise quality.

Depth of field is affected by aperture, but really tiny apertures can result in diffraction of the light (leading to softnes or less sharp images. Optimal sharpness can be tested for individual lenses. Softness due to diffraction often starts sooner than people think as the opening gets smaller.
For the homemade landscape challenge, you probably are doing close up or macro photography. This often is associated with a shallow depth of field. It may useful to note that depth of field is affected by distance to your subject (focus point). Here is a tutorial that might help with the concepts: link . With an online calculator like this calculator, you can test your expectations. Can you back off a bit to increase depth of field then crop away the surroundings?
You probably will find that your difficulty with depth of field relates to physics as much as or more than your skill. Just the nature of macro photography. "Focus stacking" is a good search term to use for more information about combining nearly identical shots taken at slightly different focus points.
Another alternative is to focus on the best point in your little landscape so that the out of focus areas enhance your image by directing attention to the most important part of the subject. Artistic intent can allow this, even if your first thought was to seek uniform sharpness.
