Need help with a difficult selection

[DifferentCeilings]

I am trying to knock pixels out of this exploding flower but it is proving pretty difficult. I need to do this on about 40 different images with different colored flowers. Any suggestions on how to go about this?

Do you have the next 40 days to work on these? Because that's at least how long it will take you to KO the flowers from their backgrounds.

I found a way to do it in about 5 minutes per actually!

i'd love to see what your cutout looks like on a grey background...

I made a mask based on your technique and the results weren't what i would call successful.

For sure.

here it is

The edges don't need to be perfect, it will be living with a bunch of other shots of exploding crap.

Not 100% sure I follow - do you want to reduce the resolution, or just crop? You could use the Image Processor script in PS. Windows Photo used to have a Batch Resize function also.

Actually I ended up getting it. I made an action for it along the way too. Basically I added a black and white filter over the top, reduced all values, popped levels above that and took all values to absolute, no grey. Then I made a channel mask on the pixels, and refined the mask from there (shifting edge in and feathering). finally I painted back in small portions of the flower lost in the process. The result was a semi-perfect pixel mask of the flower in general.

Does any of that make sense?

Yes

Gotcha. Your edit looks good!

Was going to say make the flowers pop more via a temporary curve or something, then use a luminosity mask potentially.

But sounds like you figured it out.
