Which is best?

Hello all,


I was unsure which version of a photo to choose for my latest gallery post (the one featuring the 5U3C tube here.

So, I thought it would be interesting to hear your thoughts on which of the other photos you prefer.

All were taken with a Pentax K10D and the SMC-A 50mm f/1.2.



















Thanks in advance

Nos. 1 or 5 for me, my favourite is no. 5.

No 5 without a doubt!

Another vote for 5 for the most aesthetically pleasing, although like 4 too for the clarity of the inner workings of the valve.

Number 4 for me.

Thank you all for the feedback - it's appreciated
