Anyway to get more of this in focus?

Using a pretty decent micro lens, the Nikon 85mm f/3.5G AF-S DX ED VR, i wanted to get the ENTIRE car in crisp clear focus, so i used a low aperture f 4 but half of it was still out of focus.

anyway i could have gotten more in focus?

You used the wrong aperture. To get depth of field you need a SMALL aperture = a big number.

Try using f/22 and focus on that thick black detail just behind the front wheel.

If you want to get more of the car in focus, you need to use a smaller aperture like f/16 or lower.

It seems that you have an excellent macro lens, but to not yet have the understanding necessary to use it.

If you understood the fundamentals of photography, you would have known three things at least

* the longer the macro lens, the shallower the depth of field will be at any specific lens aperture
* smaller lens apertures will produce more depth of field
* the apparent depth of field moves one third toward the camera form the focus point and two thirds away

Now with these things in mind, reshoot your subject.

It may be that you will need either more light and a tripod, so consider this before you shoot your

If you look closely, you will see that your actual focus is on the foreground, which means everything behind it is out of focus. Manually focus on the door post and try again

NOTE: Most beginning and novice photographers attempt to use auto-focus when using their macro lenses. Advanced amateurs and pros almost always manually focus their macro subjects

Besides using a small aperture in the f/16 to f/22 range, you can also increase the distance between the camera and object. Since you have lots of pixels to play with, you can crop the image without loosing much.

Wide aperture WRONG!
You need a small aperture to get greater depth of field.
In any case, you can't now change the image you already have.

Focus Stacking Software!
With focus stacking you take multiple photos of your object. Each photo focused on different parts of your scene.
ie 1st shot foreground, 2nd shot midrange, 3rd shot background.
Then use software like "HeliconFocus" "Zerene Stacker" or free "Combine ZM"
Then you select you multiphotos with any of the above software and they will select the focused parts of each photo and produce one single photo in focus.

Also you should have used f/22 or f/32 not f/4.
But for good detail use f/8 and the above programs. Also use a tripod.
Look up various "Image Stacking Software" there are different kinds for different purposes.
