[Greg] “‘ve got jpeg logo that’s black with a white background”

If the logo really is black with a white background this is pretty easy.
First, open your document in Photoshop
– Create a new RGB document with 768*576 Pixels (PAL) or 720*540 (NTSC)
– Make the whole image black
– go to the “Channel” palette and create a new channel (button in the lower right corner). You now should see “5” channels, RGB, Red, Green, Blue and Alpha. Actually these are only 4 channels, since RGB is Red, Green and Blue together
– Select the “Alpha channel” in the channel palette and make sure that it is black
– Open your jpeg with the logo
– Select all (CMD A) and invert the Logo (CMD I), Copy it (CMD C)
– Back to your new image. Make sure that ony the “Alpha” channel is selected/blue in the layer palette. Paste your Logo (CMD-V).
– Place and resize your logo as needed. Remember that you should stay within the title safe area to view the whole logo on a video screen
– If you click on the eyes next to RGB in the chanel palette you should see much red with a black logo where you have placed it. Actually the B&W logo is acting as an alpha channel for your black RGB layer. This way you don

Thanks Floh,

It’s still not working. I get to the point where i see the red but all I see is a faint outline of the logo. I’ve saved this as a tiff, but when i import it into m100 all I get is a black screen with the logo outline. Any thoughts? I must be missing it somewhere. Thanks for your help

It could be a problem with the JPEG. When opening the JPEG file, go to the Image->Mode menu and make sure it is set to “RGB”. Then do the invert.
Does the inverted logo look okay? Basically what

Hi Floh,

Thanks. I actually figured it out by turning on the alpha channel in graffiti. It worked. Thanks so much for your help.
