Can't Figure It Out

when i open a colour image file it opens in black and white, help please

Hi,When a black and white image is engraved by laser engraving, the engraving itself appears white on some materials.In other words black in the image is engraved white and white/gray gradually becomes transparent. (This is not simply the black and white image inverted)This is an example:



can I simulate this effect in Adobe Photoshop (CS6)?





Mod edit: The link was dead. Please upload an image if possible, thanks.

does anyone know how I implement the black strip on on this flag in the attached photo?

Hi all!
We're using photoshop to prepare assets for a game engine, and i'm trying to find a good workflow, which i can then teach to my artist.
At this point, i have an image with five layers. 12345

Layers 2-5 each have a layer mask on them.

Now what i want to do is, copy the layer mask of layer 2, and paste it into the Red colour channel of layer 1
then mask of layer 3 into the green channel of layer 1
layer 4 into the blue channel
and layer 5 into the alpha channel

So the result is that the channels of that layer will each look identical to the layer masks, and thus layer 1 will look like a wierd (but programatically meaningful) mishmash of colours.

I'm having some problems though.




Apologies for the massive image.
This is the green channel that i've gained from the above procedure. The big gradiented circle in the middle is what i made, but for some reason i have this white stripe down the left side too. I have no idea what that is or why it's there. It appears on both he green and blue channels when i paste in a mask. But if you look at the channel image in the right hand panel, it doesn't seem to have a stripe down it.

the stripe is definitely there, it's affecting the main image, and its annoying me.

any thoughts what might be causing that?

Hi,

Today I saw a picture that looks different on black background and on white. There is an example attached. Does anybody knows how to do this? I found an explanation on the link below, but doesn't worked for me (when I create the subtract layer, it doesn't result on a transparency layer):

graphicdesign.stackexchange.com/questions/9088/image-that-looks-different-on-black-background-and-on-white

All I know is that the final image must be a PNG file, with transparency on it... But don't know how to merge the two images to get the effect of different images depending on the background color (black or white).

Can anybody help me to understand that effect?

Hello,

I am completely new to this forum so I apologize if this is posted in the wrong place. I am using Adobe Photoshop Elements 9 and have a question regarding file size/quality. So, here it goes.

I am currently working on publication that requires all downloaded photos to be uploaded to a website that has a max file size of 20 mb. When I download an image to use for a background (some sort of a pattern that is normally somewhere around 800 x 800 size) the image is about 180 kb which is perfect. Unfortunately, the image has a poor ppi resolution and prints extremely blurry so in photoshop under image size, I increase the resolution so that the file size & resolution is bigger. This takes a lot of guessing on my part.

For example, if I increased the image resolution to 100000000 ppi, the file size would end up way over 20 mb which does me no good. So what I am wondering is, is if there is a way to optimize the the resolution of the image, given the file size limitations, without all of the guess and check?

If this looks confusing, I apologize and will gladly explain more. Any help would be greatly appreciated.

Hey gurus! I'm trying to post to the show board for some CC (constructive criticism). I can't seem to upload. I keep going to upload and it shows the image loading but never finishes nor appears available to upload. Is this an operator error? This is probably something that has an easy solution and asked often. If so, sorry to repeat the question.

Tips, advice?
Thanks

I have a PNG image that I have changed.

I'm wondering why it looks so different from the original.

I don't have the layered PS files so had to work off the PNG file...

The top one is the one I changed. The bottom one is the original.

Why is it that the original looks so clean and the revised one has little black lines underneath the icons etc?

Is there a different way to save that I should be using? I just chose save as: PNG

Any help would be appreciated.
