UntitledSteel Teeth

By Sone  
Taken as homework for my Dynamic course. I went looking for scrap and rusted things. I found this pattern on some kind of construction machine.

Interesting abstract and I like the composition with the strong diagonal lines cutting through the frame. For me there is too little in focus. I would have liked to see this sharper through the frame to show the texture in the slightly rusting steel teeth.

Selective choice of focus point to control the depth of field along with a smaller aperture to give greater depth of field. By selective focussing the area of depth of field at a given aperture is greater behind the point of focus than in front. This means that you may choose to focus slightly forward of the subject point to maintain that area in focus but improve sharpness across the frame. I hope that makes sense. Worth googling depth of field and reading up to understand this better. There are also free apps for phones that will calculate the depth of field for you when you input an aperture or give you an aperture required if you input the distance of area you want in focus.

Promising close up, good composition and interesting detail just not enough of it in focus for me.

Where were you focusing? I assume top right? But nothing is in focus. The whole point of shallow depth of field is to create a contrast between a selected area of interest, sharp and precise, isolated against softer surroundings. Here at f5.6, focusing carefully on that long blade would have given you a strong diagonal with good textures, hard and tactile, with blades fore and aft gradually moving out of sharpness. But the larger the aperture the more carefully you have to focus!
There are some good ideas here - diagonal lines are generally more dynamic that straight horizontals, and give scope for abstract effect; and the light and shadow here are gentle and very attractive. But work on your focusing!

You are using a tripod I hope. For an image like this to work it has to have an area pin sharp and nothing is pin sharp so it looks like movement. A tripod, a bit of stronger directional lighting and a smaller aperture, f11, for a rather stronger image.

Thank you all. In class tonight my lecturer was very impressed with this photo. I am proud to say that she said the focus and composition is perfect. She would also suggestbflipping the image, although I think I like it this way the most.

That just shows how subjective photography is, perfect for your lecturer. Pander to your lecturer as that is where the pass mark comes from.
