hello, i have some experience with photoshop but i stumble upon such obstacles sometimes. i know what i want done and how to do it but i am not familiar with the menus and options/settings required to achieve this effect.
currently i have two images - one of a background and one with the same exact background and an object in the front.
i want to remove the background to leave just the object in a transparent background.
tried playing with the vector masks but the only thing that seems to have any effect is the "exclusion" blend mode and it seems to invert the luminosity.
thanks.

if you are just trying to remove the background of an image, it can be done quite easily in power point...I've done it myself and it is very effective.

feel free to pm me the image if you'd like me to do it for you.

Bump

1. Open up both images.
2. Place the image with the object above the background image.
3. Click the object image in the layer's palette to highlight the layer.
4. Click the layer mask icon on the layer's palette that looks like this: [ O ]
5. Click 'B' or select the brush icon from the tool's palette.
6. Everything you paint black will erase. Everything you paint white will restore.

The left and right brackets '[' or ']' will increase/decrease the size of your brush.

If you want to erase large areas quickly, rather than brushing everything away, then use your lasso tool (L) to make a selection. Click and hold down the lasso icon on the tool's palette and then select polygonal to allow multiple clicks to make your selection. Once the selection is made, then you can fill that select with black or white using alt+delete or ctrl+delete, depending on what colors you have selected for your foreground and background. Ctrl+D will unselect the selection. Ctrl+shift+I will invert the selection.

Remember ctrl+Z will undo an action. Ctrl+alt+Z undoes multiple actions and ctrl+shift+Z redoes multiple actions. 'Z' selects zoom. Holding down alt will allow you to click and zoom out. Holding the space bar down will allow your to click and drag your workspace around.

Let me know if you have any questions.

im not sure if anyone understands my post but i don't want to use any tools by hand, drawing around images
i want the background layer to subtract all equivalent colored pixels with a blending filter that only has to be selected,
something like a greenscreen in video production
i'm sure this is doable

it's not.

It is you have to create a clipping mask not 100% sure on how to do it but i know you can

entry level computer science classes will teach you how to write a simple program to do exactly what he described. works best when the background and the image you want to remove the background from are the exact same (lighting, positioning, etc.).
ofc that's one step further and isn't in photoshop (that i know of)


you're best off not being lazy and just using the tools you're given.

eraser tool / background remover tool / magic erasor tool, pen tool, quick selection tool / magic wand tool, lasso tool

the bolded ones are the lazy/quick tools that should help you with what you want.

if you're comparing two images to a greenscreen, then it should be very simple with the magic eraser/wand tools. you might have some quality loss on the edges of your image that you're making transparent. if you want quality cuts, you're gonna have to go in and do work by hand.
if you're trying to cut an image with say a landscape in the background rather than a single plain color, you might as well start with the eraser and pen tool rather than wasting your time with the magic tools.




pretty sure you still have to create the shape of the image you want to clip. he wants something lazier.


so tl;dr
take some computer science classes and learn how to do this
or stop being lazy and spend a few minutes with the tools given

not a problem to cut out pixels by hand but not what im looking for here

Sounds kind of pretentious. I fail to see the point of acknowledging a literal possibility when you consider the comparison of time, effort, and knowledge required to achieve the same outcome. The fact that OP has spent this much time not achieving his desired outcome by now is ironic.
