There have been myriad excellent pieces posted in the gallery over the past three weeks, but one in particular stands out to me for its beautiful timber, lovely form, interesting surface treatment, and stellar photo. @Mark Durrenberger's Ripples in Apple is a winner.

One thing worth noting is the vase is quite a bit smaller than it appears. I was surprised that it is only 6.5" tall. To me, this is a good thing, as a hallmark of a great form is that it is size-independent. Certainly, large turnings and small turnings have their own challenges, but a piece like this can be scaled up or down and it will still look fantastic. Especially with such lovely, curly grain. Mark's use of aquafortis (nitric acid) enhances the curl. Like he mentioned, this reagent is commonly used in the gunstock/rifle world to selectively darken and accentuate figure in woods such as Maple, Cherry, and Birch. I've not seen it applied to Apple before, likely because Apple is not so common of a wood choice in that world due to fruit wood's tendency to crack when left thick. Great choice here, Mark, as you've achieved an interesting color that borders on metallic.

I also have to commend the photograph. Like Emiliano has mentioned before, the AAW shares these featured turnings (as well as the winning monthly challenge piece) on its social media accounts and emails. Although photography is not technically part of turning, it is an important way to accurately share a piece when most folks won't ever lay eyes on it. The phrase "a piece is only as good as its photograph" is becoming more and more relevant these days. Of course, the most important thing is still the quality of the turning itself, but something as nice as Mark's piece deserves an excellent photograph.

Well done on all accounts, Mark--congratulations!

Congratulations, Mark. A beautifully figured wood and a great looking finish. Nitric acid treatment is a new method to me ... learned something today! I also missed this one when posted to the Gallery.
 
Thank you Michael and everyone. I'm truly honored. Since I've learned about nitric acid, I've only tried it on one other piece. That was maple and it wasn't particularly exciting. But when I saw these ripples in the apple, I got excited to try it again. As to the form, I have been working quite hard on form. The golden ratio looms large in my turnings and it shows up at least twice in this form. And yes, big pieces of apple are rare because it does crack. This wood was moderately wet when it started, but it dried nicely.

As to the photography, thank goodness "film" is free. I've shot thousands of images and tweaked my studio several times. Fortunately, I'm now able to consistently get nice shots. You can see some of the evolution of my photography on my instagram. (@brindlewoodturnings)
 
Beautiful hollowform. Congratulations, Mark. I agree that the photography makes all the difference.

In the gunstock world, aquafortis isn’t just nitric acid. It also contains iron which reacts with tannins in the wood to cause the darkening and contrast in the figure. Depending upon where you buy aquafortis, it might also contain hydrochloric acid, but I don’t know what that does to the wood.

I only recently learned that it also has iron. I purchased it from a site that supplies rifle makers. https://www.trackofthewolf.com/Categories/PartDetail.aspx/392/1/AQUAFORT-2
 
@Michael Anderson i noticed in your picture a pet on your shoulder. But I can’t tell if it is a dog or a cat (if I had to guess, dog). And I noticed it because in my picture there is a pet on my shoulder too. A cat. He is Dakota. A Devon Rex. And one of the best cats we’ve ever had.
Something about great minds think alike. ;) Dakota looks like he's got a spunky attitude. Love his big ears.

Mine is a dog, Jessup. He's a Wire Fox Terrier. We got him when he was about a year and a half old. He'll be 10 this summer. Time flies. He's my adventure buddy. This is from about 6 years ago. One of my favorite photos of us together.
