    Irregular Halo

    I have a shop and use photoshop to sort out my photos. I have curved various coloured items in a block and after removing the background in various ways I am left with a jagged halo.

    I have tried to remove it by various means. I don't want to remove a similar amount of pixels from around the central photo as the black halo is different depths and also in some cases is not all the way around the circumference. Defringeing is the latest one and that didn't do anything. I am using the magic eraser to remove the background initially.

    I tried the darken and lighten tools but as the area contains several colours it didn't work well in all areas. What i need is a brush that will just remove black pixels from the edges of the image without affecting the rest of the image!

    Been trying to do this for two weeks so getting a tad frustrated and irritated by it.

    Re: Irregular Halo

    I think it's a question about selection and removing backgrounds. Google selection tutorials and look for ones that include adjusting the channels.

    It is an imperfect science.

    Ok, just to make matters more clear, are you adding a Curves Adjustment or a Curves Adjustment layer?

    Are you adding the Curves Adjustment to several layers at a time or are you adding the Curves Adjustment to a "Group" containing several layers?

    Re: Irregular Halo

    This is how the photo starts
    Irregular Halo-blackbunniesnadtoadstools-jpg

    Then i remove the black background with the magic eraser and i am left with a thick wavy line around the image like this - hope you can see it. It is very irregular as you can possible see. will try to get a better one if not.

    I have tried lots of ways to get rid of it including enlarging and going round deleting the lines individually it's driving me nuts. Theres got to be an easier way. I can do it with the modify and smooth and the modify and expand but the black edge is thicker in some places than others so this even reduction all round the image doesn't work.

    Re: Irregular Halo

    I don't see a halo. Are you referring to the leftover or remnant black background?

    If so, you just need to use a different method for removing the original background.

    Re: Irregular Halo

    yes i am talking about residual black background I thought it was called a halo. I have tried the magic wand and the quick selection tool and I get the same result. Any suggestions most welcome.

    Re: Irregular Halo

    Here I used the Quick selection tool.

    I then added a layer mask witch I did have to clean up only two places on the blue thing (???) in the middle using the Brush Tool.

    I then duplicated the layer, applied the layer mask on the dupe.

    Then I used LAYER > MATTING > DEFRINGE > 2 pixel setting, hit OK

    Re: Irregular Halo

    I have this problem with wanting to hurry up and get something done, instead of quick selection or wand, use the pen tool to get your points to be exact. The pen tool takes up more time but you will be able to cut out exactly what you want out, rather than using photoshops UI to figure out most of the work and ultimately not getting everything. The pen tool is the perfect selection tool when removing backgrounds.
