ON	THE	INTERNET 	 Suppose	you're	chatting	with	someone	online	(in	an	unprofessional	setting	in this	case)	who	invariably	types	without	proper	capitalization,	and	all	of	a	sudden the	first	words	of	each	sentence	are	capitalized,	they	are	likely	on	their smartphone	which	auto-capitalizes	their	sentences. 	 When	detecting	by	sight	if	a	photo	has	been	edited	using	photo	manipulation software... 	 Look	for	illogically	smooth	skin. 	Check	for	errors	or	inconsistencies	in	lighting, shadows,	reflections,	and	scale. 	Look	for	repeated	pixels. 	 When	looking	at	photos	online,	check	the	metadata,	found	in	“properties”. 	This data,	stored	in	what	are	called	“EXIF	tags”,	may	be	able	to	tell	you	the	date	it was	taken,	the	camera	used,	possibly	the	location,	and	more. 	Note:	there	are tools	to	remove	this	metadata. 	 There	is	a	website	called	Foto Forensics. com	that	allows	you	to	determine	how much	a	photo	has	been	edited,	using	what	is	called	an	Error	Level	Analysis. 	 	 PRINTED	TEXT 	 Text	printed	with	an	ink	jet	printer	will	have	tiny	splatters	around	the	letters,	due to	the	cartridg e	spitting	out	the	ink	quickly.
