Hi guys!

I am new to photography & photo editing but I know Photoshop and Lightroom well because of playing with it for years but now I discovered a problem!!!!

I took a pic of a baby with a white blanket as background - so I used the brightness control to blow out the blanket but only enough to let the baby still look nice - I then used the eraser to erase here & there where I it didn't blow out enough.

In the end the photo looked PERFECT on my screen. But when my boyfriend opened it and when I looked on another screen in the house - you could still see some parts of the blanket & where I had used the eraser on it. But then on 2 other peoples screens it looked fine again???

I know this has to do with screen gamma etc - but how do you now edit to ensure it looks reasonably good on all screens???? Please help & explain how, what where.

I have a Sony Vaio VGN CS26G Laptop - my boyfriend a Lenovo Laptop - it looked fine on mine, perfect on my moms Acer LCD & horrible on another cheaper LCD.

PLEASE help I have many of these photos to finish and dont want to waste my time by creating flops. *SOBS!!!*

Thanks
Janine

Sounds like a combination of three problems - first being that you need to calibrate your monitor. After calibrating you can be sure that what you are producing will be reasonably correct and any discrepancies on other peoples equipment will be on their end. I use an i1 Display for calibration - others recommend Datacolor products.

Second would be that laptops aren't at all good for image editing - any change in height, viewing angle or tilt will cause color shifts and changes in perceived color. That being said - as long as you realize the limitations - try to work consistently. Otherwise an external monitor would help.

Third would be that instead of using the eraser - you should be masking out or using a selection and then either erasing the entire selection with a hard edged eraser or brush. Using soft edged tools or lowered opacity on tools can leave pixels with color information behind in locations you don't want them to be. The luminosity of these pixels might be too low to display on your display but on someone's monitor that has the brightness cranked up they will show. One way to check to is to temporarily throw on a threshhold adjustment layer in photoshop and crank up the level on that. Anything that shows up white in the area that you thought you deleted needs to be gone over again.

+5

A mask will allow you not only to cover the white blanket but also to tone it down separately on another adjustment layer.

Add an levels adjustment layer and move the left (black) slider all the way to the right. If you add a mask over the image it becomes obvious where you have not removed areas that contain "color" or background. Leave the adjustment layer up until you finish masking/erasing the color/background, do your masking/erasing on the layer below the adjustment layer. When all finished you can delete the adjustment layer and know you have removed all color and are left with nothing but "white".
