I agree that Modotti's photography started out showing great promise, but became too obviously political. And I think that knowledge may lead me astray with this image - is there political symbolism in the hands tangled in string? If the photograph were made by someone I didn't know so much about, I may be able to see the image better for itself.
As it is, I find the composition interesting - the position of and detail in the hands - the pattern of light and dark in the background.
Tina certainly did lead an interesting life. Though I would disagree with her politics, I have to admire someone who worked so hard for what she believed in.
