Transparent glass fail HELP

New Here ,
Nov 30, 2018 Nov 30, 2018

I've been struggling with this photo, i've been working around in gfx for a little now and a chandelier company approached me. Now i working on this class fixture and my having a really hard time getting the glass to go transparent. The picture i started with was not the best but i was told to do my best i was wondering if there is something i can do.

Help 1.png

The layers are the extra wires that i havent made into a folder yet for the most part ( I dont think i need to add the original image so i just put up the cut one )

help2.png

This is as close to transparent as i've been able to get while keeping the glass detail

I would turn them into Wavefront | Obj (in Photoshop) to get the correct basic shape then rendor them as glass (in Dimension) against a sky background... this gives you a psd that you can add finishing touches in Photoshop

This is not a scripting question.

It would be helpful to post a section of the original - as a png with transparency

The original image is too big to post in here

It was over a white back drop and the lighting wasnt too great

Is there something else i can post to maybe give you a better idea of what needs to be done?

i just need the glass to be transparent.. most of the wires were removed and replaced because they were REALLY not straight. Meaning, my original layer has primarily glass.

Hi

I was thinking you may be able to try something with blend if or curves and masks in a smilar way we would generate a chrome effect but it is hard to tell with the checkerboard and low resolution. Hence the request for a full resolution section.

To be honest though - I am doubtful that you will get a realistic effect and I would be tempted to look for another image or model it in a 3D app

My trick for glass and other transparent materials, (which works in some cases not in others lol)

Make a copy of the glass and drain the color out- copy and paste this into a layer mask of your original glass layer.

From there you can invert, blur, adjust levels on this layer mask to (hopefully) get results you are happy with

Have you tried a Color to Transparency/alpha filter? Photoshop doesn't have one on offer unfortunately, but either PhotoLine or Krita will do this, and I find it makes life much easier in situations such as the one you are in. These type of filters "unmultiply" a selected colour from the image.

Krita is free, while PhotoLine is inexpensive and has a fully functional 30 day trial. PhotoLine's Color to Transparency non-destructive filter works best in most cases in my experience. Load your image, select menu Tool-->Color-->Color to Transparency, and use the eye dropper to pick the colour to remove. Use the sliders and histogram to adjust the effect. Multiple Color to Transparency filter layers can be added for fine-tuning. And adjust specific areas by painting in the mask with grey or black to fix issues with the glass.

Download PhotoLine here: www.pl32.com

Krita works quite well too, but doesn't offer nearly as much control. Filter-->Colors-->Color to Alpha.

In the end it really depends on the quality of your original, of course. Magic "remove background" and bad source photos with perfect results don't exist
