Great sky but it reminds me more of a red filter than a yellow. I wonder if Acros is less sensitive to blue than most other films so that even no filter will give a look that you can't normally get without at least yellow?
Nice.
A deeper cutting yellow like a #12 or #15 could make a nice sky, especially if the blue of the sky is particularly saturated. Either way, I like this.
Love the composition, the tone and clouds of the sky and the fence. The risk you have taken in my opinion --you have called it "cornfield". Finding the corn is difficult at first considering the tone it represents. So... "fence and sky" perhaps?
