Her other work is also well worth a look:
I like the thin layer of mesh over her legs - looks like a wash later on in the process.
Heavy draperies added to censor the painting seem to follow the same shape on the lower body, and the article mentions Artemesia's delicate glazes under the overpainting.
So though the article doesn't categorically state that she painted this translucent veil, or if it is included in the digital reconstruction to indicate a query researchers were unable to resolve categorically, she included similarly diaphanous fabric in this nude https://upload.wikimedia.org/wikipedia/commons/b/b0/Artemisia_Gentileschi_-_Sleeping_Venus.JPG
Glaze! That's the word I couldn't remember earlier.
Eh, wash & glaze are kinda the same from our perspective as viewers - just differentiates type of solvent used, as determined by binding media.
Yeah, it only really matters with oils... need to go fat/thick over lean/thin otherwise the paint layers tenses and cracks off. Great fun
The woman who introduced the reconstruction noted that the fabric they painted over her lower half was harder to "see" under, so it might still not be exactly as originally painted, but it's definitely closer than how it is now.
