There are some reports of people training photographic memory using visual afterimages, and this is actually how the military trains pilots to recognize various aircraft at a glance. I haven’t had the time nor motivation to try this myself, though I did plan at one point to try something like this with a cheap vr headset.
As for more enhancing visual episodic memory significantly, I have encountered quite a few substances which are able to do this, the most potent being dextromethorphan. Dextromethorphan is unrivaled in its ability to enhance visual memory recall and visual thinking IME. A dosage of 90-120mg Dextromethorphan HBr on an empty stomach is enough to elicit this in naive individuals depending on weight and body composition. CDP-choline also seems to enhance the effects of DXM in this regard. The most successful stack I’ve formulated thus far for storage and retrieval of visual information over the long term was a stack of Dextromethorphan HBr 270-300mg/day in divided doses (120-75-75 for individuals with a lower BMI and 120-90-90 for higher, separated by 5 hours) (keep in mind I had been using it for quite awhile, so much smaller doses or less frequent dosing may suffice. Start with 60-90mg and work your way up, growing comfortable with it before adding multiple doses. The duration of effects is about 5 hours, with a few hours of subtle aftereffects lasting up to 8 hours after a single dose.), piracetam 3.6-4.8g x2 depending on personal preference, CDP-choline 250-500mg x2 dosed with piracetam, and PRL-8-53 10mg sublingual x2. FWIW, I’ve also experienced with higher doses of DXM with doses on the high end of huperzine A (500-1000mcg) with and without CDP choline and experienced far less day-to-day functional states but a greatly enhanced recall of visual episodic memories with incredible vividity and detail. I should mention my unique past, having taken adhd stimulants since age 4, starting with adderall and moving to ritalin at age 6–I have exceptional memory, especially visual, auditory, tactile, and gustatory episodic memory, which could be described as photographic or eidetic depending on how you define it, but it is greatly enhanced by dextromethorphan and further enhanced with cholinergics, piracetam, and PRL-8-53. Some of the things that impair that memory is overstimulation, anxiety, excessive doses of stimulants or caffeine, bupropion, and gabaergics acting on gaba-a. mu opioid agonists also impair acquisition and possibly free recall or intentional retrieval of episodic memory. I recall studies which claimed nicotinic receptor activation is ideal for storing memories and less activation or antagonism is ideal for retrieval. I have quite a bit of information on the subject if you’re interested when I have free time but I felt my experiences may be relevant here.
