@hgpennington @hgpennington.bsky.social · 20/09/2026Thank you 😊 It's life-size, ca. 8cm long. If you'd like, I can recommend my tutor's Patreon. She has a set of mini exercises that work through the fundamentals using small fruit, flowers and leaves. I find them much more approachable than jumping straight into complex subjects. 110
@hgpennington @hgpennington.bsky.social · 20/09/2026I've done similar things before! Good that you took one photo - it's definitely eye-catching 011
Reposted by @hgpenningtonNullPointer 🍄 @nuiipointer.bsky.social · 16/09/2026Interesting fungal find: This parasitic plant fungus (Exobasidium karstenii) lives exclusively on bog-rosemary (Andromeda polifolia) and makes some of the leaves much broader, and purple. The green and the purple leaves here are the same plant! #naturephotography #fungifriends 49414

@hgpennington @hgpennington.bsky.social · 07/09/2026In 2025 I painted Prunus necrotic ringspot virus (PNRSV) on rose. It’s not possible to tell ringspot viruses apart based on symptoms alone.
