Six reason to like LPD:
1. Reduces Dektol black stains in the developing tray.
2. Allows minor color shifts
3. Longer shelf life than Dektol in a working tray, stored as stock solution, and higher tray capacity.
4. Cheaper than 130 which is a better developer than Dektol
5. Avoids Metol
6. Now this is real subjective....is it just my perception Dektol dumps delicate shadow separation.
