Select>Color Range - Select: Highlights - Click OK
If background layer, unlock by dragging lock icon in the layer panel to the trash can
hit delete key
All the white should now be transparent.
If not, post a screen grab with the layers panel open, so we can try something else.
A bit more of an explaination for the above post.
In order to see a transparent background, the bottom layer must be unlocked which is why it is important to drag the lock icon to the trash can.
When saving the file use a format that supports transparency. PSD, TIFF, PNG are all good candidates, do not use jpg as it does not support transparency.
Your method worked perfectly! Thank you for your help with this.
I tried this method but my Mac keyboard does not have a Delete key. I got as far as dragging the padlock icon to the Trash but no further - can you help?
I have a problem - I try to create new file, set background to be "transparent" or I try to creat a new layer, both give me white background.
Is there anything I am supposed to turn on/off? My color mode is RGB 8 bits .
On this note, what color mode should I use in general?
Thank you all so much!
To make background transparent, I go to quick selection tool -> select the item -> inverse -> smooth -> refine edge -> tick smart radius -> radius 3px -> smooth 4px -> tick decontaminate color -> output to (new layer with layer mask) -> OK.
Usually I do this and my background transparent.
But where is my mistake after I did this the background not change to transparent but pop up layer thumbnail and layer mask thumbnail.
Anyone can fix this?
1) Mode can not be bit map (see documents tab) You can change it by using the menu Image then Mode. Then choose RGB or cmyk
2) Once mode has been changed, then you need to covert the background layer (in the layers panel) to a normal layer by dragging the padlock to the trashcan.
You will now have a checkboard background representing transparency.
