Am I using the correct tools ?

Question

I need to edit a series of images for a product cataloge and would need these images cut out so that the back ground is transparent. I've been using magic extractor am I using the correct tool ? I also need the lines to be more precise are there any other tools I can use to make the lines cleaner on cutting out ? I just need it looking more cleaner and straighter ?

Answer 1

Use Magic Eraser tool changes all similar pixels when you drag within a photo. If you’re working in a layer with locked transparency, the pixels change to the background color; otherwise, the pixels are erased to transparency. You can choose to erase contiguous pixels only, or all similar pixels on the current layer.
Original image (left), and after erasing the clouds (right) 
In the Layers panel, select the layer containing the areas you want to erase.Note: If you select the Background, it automatically becomes a layer when you use the Magic Eraser.
Select the Magic Eraser tool in the toolbox. (If you don’t see it in the toolbox, select either the Eraser tool or the Background Eraser tool , and then click the Magic Eraser tool icon in the options bar.)
Set options in the options bar, as desired, and then click the area of the layer you want to erase.You can set any of the following Magic Eraser tool options:
Tolerance Defines the range of colors that will be erased. A low tolerance erases pixels within a range of color values very similar to the pixel you click. A high tolerance erases pixels within a broader range.
Anti‑alias Smoothes the edges of the area you erase, making the edge look more natural.
Contiguous Erases only pixels that are adjacent to the one you click. Deselect this option to erase all similar pixels in the image.
Sample All Layers Samples the erased color using combined data from all visible layers. Deselect the option if you want to erase only the pixels on the active layer.
Opacity Defines the strength of the erasure. An opacity of 100% erases pixels to complete transparency on a layer and to the background color on a locked layer. A lower opacity erases pixels to partial transparency on a layer and paints partially with the background color on a locked layer.
