Recent detections of massive quasars at z > 6 has proven to be an interesting challengefor cosmology given the short time frame that these objects have to reach a certainmass via conventional methods (e.g., galaxy mergers). Direct collapse black holes(DCBHs) are theorized black hole seeds that propose a neat solution to the formationof supermassive black holes (SMBHs) by z ≳ 6. During this report, we followed thefirst photometric method developed to identify these black hole seeds, adapting it tothe James Webb Space Telescope (JWST ) photometric system to facilitate its usefor upcoming data. Two DCBH models were used to discard nearby objects (e.g.,cool stars, brown dwarfs and giant exoplanets) as possible interlopers, and allowed usto identify a possible confusion between DCBH signatures and high-redshift galaxies(z = 6) within an age range of 0.8-0.9 Gyr. This confusion could grow larger if wereconsider the analysis adding dust to the galaxy models we used
