Trying new 50 1.8

Posted this on other section, but couldnt get CC, so please CC so I can do it better
Set up, Lightbox, two lights at 7 and 4, Lens 50 1.8 T1i on tripod.
Just an exercise but i WANT TO IMPROVE

The DOF of 1.8 this close is around a half an inch or less. Which is why most of the pictures appear soft except a very skinny part of the object. Try making the aperture smaller to get more in focus if that is something you are going for.

exactly if you want the whole oject in clear focus go with something closer to f2.8 to get a claner image it seems you have plenty of light so you should be good.

They were taken in f8 if my exif is correct.....
In the plane pic I wanted that, bot not in the other 2, but still think needed more f.

What was your focus distance? That is an important part of DOF. If you were at the minimum focus point for the lens - 18 inches - then your total DOF was almost one inch split evenly between front and back.

After the softness what I see is noise in the shadows. Smart move on the tripod but opening up the f-stop a bit would have probably let you hand hold. How did you release the shutter, cable, timer?

Titus, after I answered the post saying they were taken at f/8, I realiced that I was very close to the objects, so thats the second factor that has influence in the DOF.
I did take them whit the shutter, but next time will do it with the timer, thank you for the tip.
BTW, its not noise in the shadows, it is the texture of what was under the glass when I took the pic, but Thanks for letting me know, I will not make that mistake again.

If you want sharpness for these closeups you might try focus stacking. It's a little more work but results can be very nice. You can check it out in the Macro Forum. Otherwise I'd try stopping down more to f16 and use a flash if necessary.
