glass background

Hi guys

These is my first post in te site
And I hope you can help me


Its general problem, not only with this image which i attach
Sometimes when i take a picture in a plastic transparent plate or glassy plate the table under it appears in the picture and it stuck with the photo like in the sample(red lines) - I want to know what the best way to remove it is or how to take the pictures from the beginning without it??

Thanks

Re: glass background

Batmobil, welcome to RetouchPro. Your attachment is very small to start with which makes those tiny problem areas impossible to see, or at least see clearly for me. If you have a hi resolution image I recommend that in addition to the whole image you also attached a cropped section at hi resolution showing the damaged area.
Regards, Murray

If I'm reading you correctly you are putting your items onto a transparent plate and are upset that you see the table through the plate. Seems to me you could either put the items on an non transparent plate or choose a tablecloth, etc, that you don't mind seeing through the transparent plate.

If you don't want to see the table through the plate why are you using a transparent plate, and what is it you would prefer to see in/through the plate?

Re: glass background

transparency means you see the background through the bowl. Since your BG is white you could make your bowl whiter: brighter and less blue.

I did this very sloppily by making a brightening curves (raising highlights more than darks to keep contrast/shape) layer with a black mask and painting white on the mask to brighten the back of the bowl and a spot or two of rice.

I also made a HSL layer and used the target adj tool to select the rear of the bowl, then used the lighten and desaturation sliders.

It took more to write this and load the file than to do it, so not going for beauty here, but is it headed in the right direction for you?


You might consider adding a shadow to the background under the bowl for added realism.

Re: glass background

Try selecting the glass (separate it on its own layer) and change the blend mode to Pin Light.

Re: glass background

About the hardest thing I know is to do is separate glass from a white background since inevitably it involves understanding translucence. I gave it a go (click here for the PNG file with embedded transparencies). Still best to just place your item on an appropriate background of choice.
