Parker Solar Probe (PSP) and Solar Orbiter (SolO) observe the Sun from unprecedented close-in orbits out of the Sun-Earth line. In combination with EUV imagery from STEREO and SDO, these unique and high-resolution data from different vantage points will give us new insights into the early evolution of coronal mass ejections (CMEs) in the low corona and inner heliosphere. For a case study, we apply 3D CME reconstruction methods to relate different CME substructures as observed in white-light coronagraphs like WISPR aboard PSP, to EUV off-limb structures for an erupting event. We interpret the results in terms of projection and Thomson scattering effects.
