How Do I Achieve This Dotted/sprinkled Effect?

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?

Probably a bad subject title so let me explain what I am trying to do.

I have a very basic image (screenshot 1). Trust me, this is not an exercise but similar to the image I will be using,ha!

I select each white circle and using smart erase I can erase each circle (screenshot 2) but I want a feathered/gradient effect like (screenshot 3).

Then when I add a background color it gives the effect I am after (screenshot 4).

So here is the issue - Each image will have 100's of white dots and they will be random on each image (sort of like a star field would be a good comparison). So I need to find a way to perform the same procedure all at once on all the dots (preferred way I would think), sort of like using smart erasure but with a feather effect, or need to create an "action" that will do that.

So I guess my questions a

1. Can one create a gradient that goes from "eraser-to-black", and then save it as a mask? (to use for question 2)

2. or perform the same task on each selected spot at the same time using a mask or

3. If I need to create an "action" for this how would one move from one spot to the next to perform the task on each spot?

Since I am new here I am beginning to search through the massive forums here but thought I would throw this out will I keep searching. Thanks so much.

About six years ago i made a small pixel image, enlarged it quite a bit and applied one or more filters in Photoshop to make it look cool.Now i want to make a similar effect on a different picture, however i am unable to find what i did to achieve this effect.Does anyone have a clue of what it is that i might have done? i have gone through every single filter in CS5 and i am not finding anything that produces the same effect.

Here is the before pixelated pictu



Here is the after picture (added color to eyes manually):


Please Help!

I am doing a tutorial that calls for dotted lines. I believe this tut is done with the newest version of Photoshop out there, so it has no problem making dotted lines. But I just cannot find a way to make them with my CS3. Dotted lines have always been easy in other graphics programs I've used.

I tried going to Style/ Dotted Strokes and I get a halfway decent result by using "no fill". But I can't get the lines in any color except white or black. It's not very editable, either.

Is there a way to get dotted lines or strokes with CS3?

Thanks,

i have a signature watermark i put on my favorite images currently i have it is saved as a psd so i open it then move it onto the image, i was trying too create a brush that done this but the writing is white so becomes transparent when i make a new brush and only the camera icon is visible, i also tried to create an action where i recorded opening the psd , moving it onto an image, i was hoping this would work but didnt , something about move brush not defined if i remember, also the brush i created turns out sort of a green color see bottom image i know there probably a simple way around it and would appreciate any help , ive attatched an image of the signature so you know where im at , its transparent i just put a grey layer behind so you can see,

Hi,
I'm wondering if this is possible:
The right side is what I'm trying to achieve.
It's a simple enough effect, but the problem is that I'm curious if it can be some sort of dynamic effect in that I can change the "A" text to "B" and still have the outline cut out of the "M" (Or whatever if I need to change the "M" text to "Q" or something).
Basically I need the "A" and "M" to be able to change while the stroke of whatever the "A" letter (or shape) is will always cut out whatever shape, text, or image is placed behind it.
Is this possible without having to manually cut it out of the back image every time?

The illusion can easily be created by having a white background and using a white stroke on the "A" (that creates the effect I'm wanting)..
However I need them to be transparent and easily editable so they can be saved as transparent images for multiple uses quickly and easily.
(I apologize if I didn't get this across very clearly)

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)?

Hi I'm quite a noob.
I would like to get some help creating this effect in photoshop.
1. The effect of having a gradient-like effect of the background. Is it made by creating a solid color and then using a large pixel soft brush to create the light effect?
2. The torchlight like effect of the images of the girl and the hands.
Thanks.

Hi all, I'm new to the forum and I'm a freelance researcher in image editing.
I'm italian, so sorry in advance for my english .
I'm also a little crazy , I left my job as employee 'cause I believe in my researches and I want to make them my only job.
I developed a new effect for substituting colors in images. I would like to test the goodness of this new approach useful for retouching photos ... so I ask you a little collaboration, if you want to help me, you should retouch the image that I attached in this way: change the color of the pen fromred to white.
It's important to me to know how much time you spent in retouching the image and what applications you used for achieving the result, so please post the altered image together with the requested info. In a few days I'll post the image elaborated with my algorithm.
Really thanks to all, in advance, for the collaboration.

Hello,
I am not sure if this is even a necessary worry of mine nut I will pitch it out anyway. I will be printing the attached file on the back of a white t-shirt and I wondered if there was any technique that could be used to reduce the harshness or abruptness of the image that may be seen when the image is printed onto the white shirt. The color at the edges of the image is very light / almost white so fortunetly in most areas of the print you may not be able to clearly see the edge. if I am not making any sense I guess what I am trying to say is I would like for it to seem like the image fades away at the edges slighhtly rather than seeing a clear edge of the picture. I could imagine using some kind of edge eraser tool with a spotty brush or partial opacity but not really sure the best way to try and achieve it. The picture unfortunetly has texy of my url running very close to the edges so I would like to be careful that we don't fade any text away. Just wondered I would see if there was a quick and easy way to do it. Ideas are welcome. If you do any work please post back your .psd file and a brief description (if it's not too complex) of how you did what you did.
Thanks,
Joe
