Can you isolate a small part of a photo for adjustment with Vivesa?
Yes, via "control points"

Also, when Nik is used as a plug-in to PS or PSE, you can use layers and layer masks rather than control points, if preferred. That's my preference for ease of changing my mind

Indeed!
Without both layers and masks post processing would be limited and a frustrating struggle.

Learn how to create a layer, make it the active layer, and select the target area. Then open Enhance and there are a couple choices there to use to adjust the contrast. Whatever you do on that layer you can trash it if you don’t like it or make a mistake without affecting the original.

I recently submitted an image in a local Photography Club competition of a shot I took in Venice. It was in a very picturesque waterway side street (including gondolas) and included a small foot bridge.

The judge liked the picture, but said it would have been better if I had increased the contrast of the foot bridge ... to in effect create a more separation effect from the background. I have absolutely no idea how I would do that. I know how to edit the overall contrast of an image, but not a small part of the image only.

The editing software I use is PSE 14, and Luminar 2018. Any advice on how to accomplish this would be greatly appreciated. Thanks!

That's easy to do in Luminar 2018. You can paint the contrast on the bridge only using the brush tool in the contrast slider. In fact all sliders in Luminar can be painted into whatever area you want in a photo. The process creates a mask of only the area you want affected. It's quick and easy. Give it a try.

Vivesa uses color and contrast, to lighten/darken/more contrast/less contrast brighten or darken all on a specific area that you've placed a "dot". Somewhat magically at times it does it's "thing" !

I do this very easily using the Camera Raw module in Photoshop. I haven't used Elements for a while but it may have the same function. In Camera Raw there is a vignette tool that allow you to draw ovals or circles around any part of your image and then apply any changes you wish either inside or outside of the oval. It works great as a dodging or burning tool like in the old darkroom days. I take a lot of fly fishing pictures and usually select the fishermen and lighten them up half a stop or so just so they 'pop' a bit and stand out in the image.

I believe that the elliptical marquee tool does the same type of selection as the vignette tool.

In photoshop which only costs $10/mo you can use the quick mask tool combined with the graduated tool to select only a portion of an image and it automatically feathers your changes into the rest of the unaltered image... Very effective for what you want to accomplish.

Here is a pic where I used the technique to lighten the exposure of the bird and darken the exposure of the background. My example was intentionally done in a manner where it is obvious, in the correction you are asking about it would be completely undetectable.

Kudos for showing an example - nothing beats a picture that shows what is being said. I don't understand why experienced advisors don't get that. Ask a question and you get 20 different responses none of which may produce what you're visualizing and a picture showing the results of applying a particular technique sorts it all out instantly.

You can duplicate the layer, while the new layer is still targeted, create a black layer mask on the new layer by holding down the Alt key and clicking on the create layer mask. Changing to a contrast blend mode - overlay or soft light will increase contrast. But you won't see it because the black layer mask is blocking the entire image. By painting on the layer mask with a white brush you will reveal the high contrast image below - and confining the painting to just the bridge will reveal the high contrast version of the bridge. You can adjust the amount of contrast either by adjusting the opacity of the brush or using 100% opacity and adjusting the opacity of the layer.

Here is a quick video that explains what I just said:

Or you can do as others have suggested and create a selection and adjust only the selected part.Depending on the image, one approach will emerge as more efficient.

Layer masking and selective "painting" is the method I generally use, and have found it to be a great way to isolate part of the image. You can also use luminosity masks, but there are a number of steps to be taken and it appears the OP is looking for a simpler approach...
