vingster, both settings adds diff spikes
thanks.
lester, many thanks for your replies. Ive also noticed the green tinge in the outer edge. I don't think it is the processing part maybe something got to do with the actual Envisage program when using the sharp setting. The green doesn't occur in my soft images. same processing method via photoshop cs2. thanks for pointing it out. might need to investigate on this.
Cheers all.
