would it be possible to remove the background on a picture like this while basically maintaining all the little details of the tree?

if so how would i do it?

Get a higher resolution version and use the Magic Wand in PS to extract the tree ( and then invert the mask to remove the background). But that will be tedious work with that kind of detail, thus a higher resolution should be more easy.
You can also enhance the black level and deepen the shadows (dark areas) of the image via the Level tool or Curves tool to make the tree more black to easier mask it via the Magic Wand.
 
It shouldn't be super difficult for an image like that where there's a big contrast difference between what you're trying to isolate and the background. If the tree wasn't as dark then it would have been much more difficult. The attached image took me about five minutes.

panoz7, what tools did you use?

I tried the method I described, but it was quite cumbersome and I haven't invested five minutes into it, maybe 30 to 45 seconds.

I started by creating two channel mixer layers to convert the image to black and white. One converted the purple sky at the top to white and the other converted the red sky at the bottom to white. I then blended those together with a layer mask. I then adjusted the levels a bit to increase the contrast, and finally I painted with a white brush on a new layer wherever the channel mixers weren't completely effective (mostly around the edges). It's then pretty simple to use that black and white image as a layer mask on the previous image to eliminate the sky.
 
I used background erasure in PS then did fine detail with normal eraser.

I would use the pen tool and trace the tree and then select the outcome and mask the tree layer.

Or alternative hide the old layer and then just use the shape layer you created. This by far results in the best quality. Much higher than any filters or eraser tools.

I need to work where you work. :) That would take forever in a picture like this.

you should totally do that and show us

This would take many hours to make. Not an economical option.

I suspect this is a sarcastic (no way practical) post. :rolleyes:
 
relatively easy

so many different ways to do this. I would do it like this.
Make image CMYK. Duplicate the Black channel into a new document. Play with levels to remove any unwanted grey from the sky.

lol, I actually had to do that to a tree once in a project. The tree was very eveningly lit with the background.

That said, this high contrast tree would be best done using one of the other methods mentioned. I may have come off a bit too "absolute" in my reasoning. Though it would be the best quality - not worth the time over channel mixing though. My tree I had to do was about 5-6 hours working through a lunch break. And the client changed her mind after seeing the finished results :rolleyes:

EDIT:
I took a look at the file and what I did was mode CMYK and deleted the CYM and level adjusted the K. Converted to greyscale and then erased some of the sky bits. Copied into Illustrator and then live traced and come up with attached in about 5min.
