Same as yesterday, this time with a 10x macro filter on the lens. Don't think I can take this subject much further; might try and capture smoke, but think I've taken 'flame' as far as I can.
Looks okay on black if you feel inclined.
You could try high end, bright white, or capture reflection of flame in glass container? How does the 10x macro filter work ( should Santa be asked??) I really enjoy macro and struggle with telephoto ( get too close) and normal( ")
