Sounds like a face tanner will work, I don't think I will be going larger than an 8x10 although I could do a photogram or a digital negative at that size, I will check out those time-o-lite timers, it might be useful for when I do my own dev work or indeed get an enlarger for negatives in the future. Could I perhaps look at getting a cheaper face tanner and simply buy the 15w UV tanning bulbs to upgrade it? Are there any more powerful tanning bulbs I could look at getting eg a 25W or something?
