How to get liquid to look transparent
-
Still very much a WIP. It will probably take me the rest of the week to finish it, but here is what I got so far.
Going to add many more bubbles, as well as some darker reflective stuff through the liquid. Also, here is another image of the other objects that I will be adding in, not including his hand nodling the fork/pokerSo since this post is mainly about reflective/transparent light, I won't post too much about the whole process, but once I get the table in, it will be interesting trying to figure out how the reflection might bounce back onto the table, as well as his glasses. I am really painting in the dark (figuratively) as I go, so it is fun to put this puzzle together.
I removed all the color from the first image and started over btw.

Great improvements! It's really shaping up and I have no doubt you'll be able puzzle out your desired results. If you ever want to take a course that deals with reflective and transparent surfaces, I recommend the Fundamentals of Lighting with Sam Nielson, over at Schoolism. You learn about reflections on metallic objects, eyeballs, water, glass and also the transparent aspects of glass and water. It's awesome.

This is a great discussion. I'm keeping an eye on this because I've wondered about all this too. Great work, by the way. I'm loving the bubbles in the green liquid.

@eric-castleman When you select "New Topic" for your post, you have to choose a category for your topic (art, general discussion) or it will tell you you don't have enough privileges. Same thing happened to me recently.

PS (or any thing with layers) it can make the "transparent" liquid process (or smoke, or ghosts, or magic, etc) a LOT easier.
With the liquid on one layer, add a layer mask to it (for non-destructive editing--if your program doesn't do layer masks use a low opacity eraser), take a brush with low opacity, and "paint out" sections of the liquid. That way, the layer behind it will show through.
This will get you a certain percentage of the way there but then you'll obviously still have to paint in specular highlights, shadows and whatnot. For that a reference is invaluable.

Just for kicks, I did a couple quick studies based on the blue liquid. My style of painting is more loose and "impressionistic" but I thought I'd shared in case anyone finds it helpful
https://youtu.be/BRKc4uBquDII think the main thing is to make the background/table show through the liquid. With the bubbles, I think you'll really have some awesome looking transparency!

@missmarck very cool!
Btw, I suck at Instagram, and for some reason I can never find people via search. Can you by chance link me to your profile?
-
Sure!

Been super busy, but have worked on this image as much as I can. I put in the table, and am working on the burner, trying to make it chrome like, as well as looking around at references for reflections onto tables.

@eric-castleman It's looking great. I love how you've kept the liquid very soft looking inside. It really helps with the mood of the piece. The bubbles really help sell it. Not sure what you have planned in terms of the marshmallow, but I think you could push it so it looks more marshmallow-like. Maybe have the stick pushing through the top of it, shorten the proportion, and have a little toasting action going on.
-
@tessw yup, we ste on the same wave length. Those are my next few ideas. I have a poker going through the marshmallow in the drawing, but wanted to wait until I had the chrome on the burner correct. Softening up the marshmallow is something I have pondered, but the mid area is the next nightmare I have to tackle, so hopefully I will get those ideas right on when it comes to that part. Thanks for the insight. Very helpful.

When i can't post an image, it is often because I didn't choose the forum I want to post on. If I click on general and then try posting the image again, it works. Don't know why that is but that is my experience.
-
Maybe if you can show a hint of the background through the liquid, like the table top lightly behind it? And the table top would be a little askew behind the bottle, right?
-
I keep looking at the thickness of that beaker, and it seems too thick. Agree on showing a little of what is behind the liquid.

Been super busy with scbwi stuff, and then my four year old son chipped his front tooth today on the side of the pool (ugh!), so just sitting down to this for the last hour or so. Here is where I am at with the body, and onto color, which will obviously require reflective color. I rounded out the marshmallow, per everyones suggestions, and finished the poker.
-
Done for the night. Any suggestions about lighting and glow to add to objects would be appreciated. Still have yet to relaly finish the foreground. Also, I'm going back and forth on him having hair or not.
-
Update. Starting to mess with transparent liquid a bit more. Struggling with how images would bend in round glass. Also, does the marshmallow still read as a marshmallow?
-
Shortened the marshmallow. Why I had it looking like I did, I don't know.
-
@eric-castleman I think it reads more like a marshmallow now that it's shortened. You might try squishing the shape a little with some indentations of where it was held by the fingers to force it on the poker. Not necessary, just a suggestion to see if you like how it fits with the piece. Also, I personally think the baldness is fine but having some wacky mad scientist hair on the side could potentially make for some good storytelling. I like how the piece is coming along, thanks for sharing your progress.
