Has anyone gone through this? I was almost done printing my final version of color neg and just when the lid was opened I was amazed about the great print. BUT THEN...... a bug like white hole in the middle of the print..... My worst fear, a mosquito printed on the paper. A mosquito sandwich.... a dead freaking mosquito that though the enlarger head was a good place to be. The irony, we are at 2c and its winter, where did the freaking mosq. come from??? I had to clean the neg and wait long before redoing the print.... I just hope the inners of the mosquito had no toxic fluids for the neg.
