Therefore, direct evaluation of the photographic result could not be directly visualized. </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>The equipments prices were relatively high. Moreover, most of the equipments were still not available and relatively expensive; and </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>converted IR digital camera could not use for regular photography. Recently, digital camera made image documentation and editing </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>easier. </em><span style="font-family: TribuneBold; font-size: 10pt; color: #231f20; font-style: normal; font-variant: normal;"><strong>Purpose: </strong><span style="font-family: TribuneItalic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>This review was aimed to explore the different characteristics and benefits of regular digital camera in IR forensic </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>photography as well as to simplify the equipments needed. </em><span style="font-family: TribuneBold; font-size: 10pt; color: #231f20; font-style: normal; font-variant: normal;"><strong>Reviews: </strong><span style="font-family: TribuneItalic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>IR photography becomes easier since certain digital cameras could </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>capture the IR image by using IR filters or to be switched to IR camera. The regular non-SLR digital camera had certain advantages </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>compared to SLRs, such in focusing.
